Abstract

Eine Vorrichtung zum Befestigen von Borstenbüscheln aus thermoplastischem Kunststoff an Trägerplättchen zur Herstellung von Bürsten, insbesondere Zahnbürsten, hat einen beheizbaren Stempel (10) aus elektrisch leitfähigem Material, dessen massiver Körper unmittelbar durch gesteuerten elektrischen Stromfluß resistiv erhitzbar ist. Der massive Körper (10) weist in seiner im Betrieb dem Trägerplättchen und den daran zu befestigenden Borstenenden zugekehrten Fläche wenigstens eine Aussparung (36) auf. Die Aussparung (36) ist auf der gegenüberliegenden Fläche des massiven Körpers (10) von einer Materialverdickung (38) umgeben. Das AFT-Verfahren kann auch bei Trägerplättchen Anwendung finden, die ein- oder angespritzte Strukturelemente wie Elastomerelemente und/oder erhabene oder vertiefte Gestaltungen (34) aufweisen.

A device for fixing bristle tufts of thermoplastic material to carrier plates for the production of brushes, in particular toothbrushes, has a heatable plunger (10) made of electrically conductive material, the solid body is resistive heated directly by controlled electrical current flow. The solid body (10) has at least one recess (36) in its surface facing the carrier plate and the bristle ends to be fastened during operation. The recess (36) is surrounded on the opposite surface of the solid body (10) by a thickening material (38). The AFT process can also be applied to carrier plates having on or molded structural elements such as elastomeric elements and / or raised or recessed shapes (34).
