Definitions
- the present invention relates to a method for firmly arranging bristles, hair, monofilaments, wires and the like or bundles thereof in or on a holding part, an application of the method for producing a specific shape of a brush or a brush, a Application of the method for producing a brush or a brush and a brush or a brush, comprising a holding part and brush or brush hair, bristles, monofilaments or wires held in or on the holding part.
- Brushes, paintbrushes, toothbrushes and the like are produced in a wide variety of ways.
- the bristle or hair bundles are held in a receptacle or in a holder by means of phenol or epoxy resin materials.
- monofilaments are generally held in a receptacle either by means of hot-melt compositions or by means of so-called anchors. It is also known to insert individual monofilaments or bundles thereof into hole-like receptacles and to weld them at the hole opening opposite the brush.
- the known methods are either physiologically questionable in part or are complex or do not allow the production of very small brushes.
- the known fastening methods for the shark th of the brush hairs, bristles or monofilaments etc. are not suitable. It is also hardly possible with the known methods to shape the brush or to design the brush surface.
- this object is achieved by means of a method according to the wording according to claim 1.
- These waves or the field lines which are applied or directed to the receptacle either excite the hair, bristles, monofilaments or wires fed to or into the receptacle or the holding part, and possibly also on or into the receptacle or the holding part. or inserted insert element and / or the receptacle or the holding part and heat them so that they are at least melted in order to produce the welded connection.
- At least one insert element is first introduced or inserted into or into the receptacle, then the hair, bristles, monofilaments or wires are supplied, whereupon a high-frequency field, an electrical, electromagnetic and / or a magnetic field is generated in order to excite or heat the insert element so that the hair, bristles, monofilaments or wires and / or the receptacle which bumps against the element are at least melted in order to produce the fusion connection.
- the insert element is first introduced or fed into or onto the holding element or the receptacle, in order to be welded to it in an excited manner by means of field or wavy lines, or mechanically or by means of gluing to be connected.
- the hair, bristles, monofilaments or wires in the area of the insert element are then introduced or fed into or onto the holding part or the receptacle, whereupon the hair, bristles, monofilaments or wires, the insert element, are drawn by means of field or wavy lines and / or the holding part or the receptacle are (will) be excited in order to trigger a further welding, if necessary, under temperature conditions which may have changed compared to the first welding.
- This two-stage process is preferably used when the hair, bristles, monofilaments or wires have a very different melting behavior compared to the receiving part or the holding part. In the case of widely differing melting temperatures, there would be the danger with the one-step process that either the hair, bristles, monofilaments or wires or else the holding part or the receptacle would be damaged by excessive heating.
- Another advantage of this two-stage process is that the holding part or the receptacle can first be provided with an insert element and then can be supplied to a supply of hair, bristles, monofilaments or wires. In this supply, the insert element is then excited, whereupon only those hair, bristles, monofilaments or wires from the supply are welded to the insert element which directly abut the latter. The manufacture of a brush or a brush can thus be greatly simplified.
- a further two-stage method according to the invention is similarly proposed, in which the hair, bristles, monofilaments or wires are first fed to an insert element which is excited and heated by means of field or wavy lines in order to at least soften the supplied bristles, hair, monofilaments or wires or melt to create a welded connection to the insert element. Subsequently, this insert element with the hairs, bristles, monofilaments or wires welded to it is fed to or into a holding part or a receptacle and connected to it mechanically, by means of gluing or again by means of welding.
- the methods defined according to the invention are particularly suitable for producing a specific shape of a brush or a brush, in that the insert element is specially adapted to the shape of the brush or brush shape to be produced.
- the insert element can be curved, corrugated, zigzag-shaped, conical, etc., so that the protruding elements from the receptacle protruding ends of the hair, bristles or monofilaments form a contour corresponding to the insert element.
- the insert element can also have hole-like or gap-like vacancies, as a result of which the brush or the brush does not have any hair, bristles, monofilaments or wires at these vacancies.
- the methods proposed according to the invention are generally suitable for the production of x-type brushes or brushes, such as, for example, paintbrushes, cleaning brushes, toothbrushes, precision cleaning brushes in mechanics, etc.
- the methods according to the invention are particularly suitable for the production of toothbrushes, both manual toothbrushes and also suitable for use with an electric tooth cleaning device.
- hair, bristles, monofilaments or wires are animal or vegetable hair or bristles, or whether they are monofilaments made of polymeric materials, such as those made from a synthetic polymer.
- FIG. 3 shows a possible application of the method according to the invention for the formation of a specific contact. door of a brush or a brush according to the invention;
- FIG. 5 shows further examples of the design and 6 a contour of a brush or a brush according to the invention, comprising so-called empty spaces;
- FIG. 7a shows a possible embodiment of a brush according to the invention and 7b sen or a brush and, schematically illustrated, the manufacturing process according to the invention;
- 11 shows examples of specific shapes of a toothbrush and 12 brush, for example for advertising purposes;
- Fig. 13a possible heating element shapes for specific shape to 13d giving a brush
- La to lc schematically shows the inventive Drive illustrated how brush or brush hair, bristles, monofilaments and the like or bundles thereof are firmly arranged in a recording.
- a brush or brush body 1 comprises a receptacle 5 which is laterally delimited by walls 3 and which has a bottom 7.
- an insert element 9 is provided, which is preferably disc-shaped, foil-shaped, grid-shaped, wire-shaped, ring-shaped or plate-shaped or as a shaped body. Hair, bristles, monofilaments or wires 11 are also provided for insertion and firm arrangement.
- Fig. 1b both the insert element 9 and the hair or bristles or monofilaments 11 are now introduced into the receptacle 5.
- the brush or brush body 1 is now inserted into a coil 21, which coil is to be arranged in the region of the insert element 9. It is important to ensure that the coil 21 is arranged as close as possible to the outer contour of the brush or brush body 1.
- a current such as an alternating current
- the insert element 9 is an electrically conductive material, such as an electrically conductive metal such as iron or copper, an alternating voltage is induced in the insert element penetrated by the magnetic field or eddy currents are generated in the insert element. whereby the insert element 9 is heated. Due to the strong heating of the insert element 9, the ends of the hair, bristles, monofilaments or wires inserted in the receptacle 5 are at least softened or melted, as is the bottom 7 of the receiving part. Thus arises a welded joint, and the hair, bristles, monofilaments or wires are thus firmly held in the receptacle 5.
- an electrically conductive material such as an electrically conductive metal such as iron or copper
- FIG. 1c shows the brush or the brush finally obtained according to the invention, the idea according to the invention being illustrated schematically in that a welding layer 10 is shown above the insert element 9.
- a welded connection can also be produced between the insert element and the brush body 1.
- a non-conductive or only weakly conductive insert 9 it is possible to insert a non-conductive or only weakly conductive insert 9 and to heat it by means of so-called dielectric or capacitive heating.
- the insert element 9 then forms, together with two plate electrodes, the lossy dielectric of a capacitor which is fed with high frequency.
- the insert element 9 is heated uniformly by the electrical losses.
- both the receiving part and the brush hairs, bristles, monofilaments or wires do not consist of a softenable or fusible material or if the melting temperature is too high, it is also possible to insert a so-called intermediate carrier into the recording, which, for example comes to lie directly over the insert element.
- This intermediate carrier then consists of a material which can be easily melted by heating the insert element so as to bring about the weld connection between the hair, bristles, monofilaments or wires inserted into the receptacle.
- Another possibility is to carry out the method according to the invention in two stages by first welding the insert element 9 to the hair, bristles, monofilaments or wires 11 outside the receptacle 5.
- the insert element 9 is then inserted into the receptacle 5 together with the hair, bristles, monofilaments or wires welded to it, in order then to be fixed again by means of welding or by conventional gluing or by the use of mechanical holding means.
- Another option is again to carry out the method in two stages, but first by connecting the insert element 9 to the receptacle 5. This connection can be made either by welding, gluing or mechanically. In a second step, the hair, bristles, monofilaments or wires are then leads to then be welded in the receptacle using the method described with reference to FIGS. la to lc.
- the receptacle with the insert element can then be guided away from the supply again, and the necessary hair, bristles, monofilaments or wires are correspondingly removed from the supply.
- the heating of the insert element depends on the one hand on the distance from the coil to the insert element, on the number of windings, on the selected wire material, on the applied field strength or current density and on the length of time during which the Insert element is heated.
- the heating of the insert element can, however, also be controlled by the selected shape of the insert element, for example mass, size and selected material play an important role. For example, an annular insert element can be heated well, while a ring which is interrupted at one point is practically hardly to be heated.
- FIG. 2a shows a brush 1 'produced according to the invention, comprising a holding part 2 1 and a thin-walled receptacle 3', in which the brush hairs 11 'are embedded.
- the melt layer 10, by means of which the brush hairs 11 'are held, can again be seen above the insert element 9.
- FIG. 2b shows a toothbrush 1 ′′ produced according to the invention, which has a specially designed holding part 2 ′′, suitable, for example, for using this toothbrush on an electrical tooth cleaning device.
- the individual brushes or monofilaments 11 "are held on the insert element 9 via a welded connection 10.
- These monofilaments can be, for example, polyamides or other polymeric materials which are usually used for the production of toothbrushes .
- the method according to the invention is suitable for giving brushes or brushes a specific contour.
- Fig. 3 it is shown in section how a brush or a brush can be made convex or convex.
- the insert element 9 used in FIG. 3 is also convex or domed, so that when using hair, brushes or monofilaments of the same length, a convex or domed outer contour 12 is set accordingly.
- Such a brush or brush is produced analogously to the method as described, for example, with reference to FIGS. 1 a to 1 c.
- FIG. 4 Analogously, a differently designed insert element 9 is used in FIG. 4, which is, for example, jag-like, the brush 1 in FIG. 4 having three receptacles 5. Again, the outer contour 12 of the individual brush or brush elements is formed in a jagged manner.
- this additional step is not necessary.
- the manufacturing methods used today for the production of brushes and brushes when producing brushes and brushes with a special shape, it is generally necessary to cut and grind the hair, bristles, monofilaments or wires before producing the brush or the brush is cumbersome. Brush shapes, as shown for example in Fig. 4, can hardly be produced with the conventional methods.
- an insert element 9 which has a hole or an empty space 13 in the center.
- the insert element 9 in FIG. 5 comprises an indentation or a groove 15.
- the empty space 13 is also located in the center of the contour 12 of the brush or brush produced according to the invention, since there is no welding of the inserted hair in the center of the hole 13 , Bristles or monofilaments. After the brush or brush according to the invention has been produced, the hair, bristles or monofilaments introduced into the empty space 13 automatically fall out again. Otherwise, the outer contour 12 has a corresponding groove or indentation in the region of the indentation or groove 15.
- areas with lower hair, bristle or monofilament density can also be created with brushes and brushes.
- the flexibility of a brush or a brush can be increased.
- contours or brush shapes can be produced without the need to cut and grind hair, bristles, Monofilament, wire, etc. before or after Manufacture of the brush or brush.
- FIGS. 9 and 10 show two further examples of a brush or a brush produced according to the invention, where no actual receptacle 5 is provided on the holding part 1, but where the insert element 9 directly on a flat support on the holding part or Brush or hair body has been arranged.
- no walls 3 are provided to the side of the insert element 9, as in the brushes and brushes shown in the preceding FIGS. 1 to 8.
- the insert element is designed as a single-stage plate, while the insert element 9 in FIG. 10 is formed in two layers, the lower part being provided in order to be let into the holding part or the body 1, while the upper part is intended for receiving the hair, bristles, monofilaments or wires.
- a welding layer 10 is shown schematically, which, however, can also be produced by means of the intermediate carrier mentioned above, if it is not possible to melt the hair, bristles, monofilaments or wires.
- Metal wires are mentioned as an example of this which, as a rule, can hardly be melted or softened by means of the methods mentioned according to the invention.
- an intermediate carrier for example consisting of a hot-melt material, which is easy to melt or soften.
- toothbrushes 1 and 12 schematically show a toothbrush head of a toothbrush 1 ′′, 2 ′′, in plan view, comprising bristle bundles 11 ′′, which have a specific specific one 11 in the case of FIG. 11 is a company name, with which the toothbrush shown can be used for advertising purposes, for example.
- the bristle bundle 11 "represents the shape of cartoon characters, with which the in Fig. 12 illustrated toothbrush 1 "is suitable for children, for example.
- 13a to 13d show various heating elements 9 as they can be used to produce special shapes.
- the starting point is a toothbrush base body 2 ", having a head receptacle 5" at one end, as shown in FIG. 14a.
- the heating element 9 shown in FIG. 14b is let into the receptacle 5 ", the bottom of the receptacle 5" being adapted to the corrugated shape of the heating element 9.
- a receiving body 3 ′′ is arranged on the heating element 9, as shown in FIG. 14c. This receiving body 3 ′′ has cutouts or passages for the insertion of the toothbrush bristles 11 ′′, as shown in FIG. 14d Toothbrush bristles 11 "according to FIG.
- FIGS. 14d have the same length, whereupon the insertion of the bristles 11" through the receptacle body 3 "into the receptacle 5" results in the shaping 12 ", as also shown in FIG. 14d.
- the toothbrush head or the toothbrush 1 ′′ is finally obtained, as shown in FIG. 14e.
- the manufacturing processes and configurations of brushes or brushes according to the invention shown in FIGS. 1 to 14 are, of course, only examples which can be supplemented, modified or modified in any way. So it is of course irrelevant whether the hair, bristles, monofilaments and the like are animal, vegetable or synthetic polymers or materials.
- Examples include sisal, ramie, pig bristles, hair of any kind, monofilaments made from metal, glass, polyamide, polyethylene, polyester, polypropylene, PVC, polystyrene etc., or wires, threads, strings made from any synthetic or natural materials.
- the inductive heating of the insert element is also only one possible example, and other examples, such as dielectric heating, heating by means of microwaves, ultrasound, etc., are possible variants for carrying out the method according to the invention.
- FIGS. 3 to 6 and 11, 12 and 14 are also only examples, and any shape and contours can be produced by appropriate design of the insert element.
