Brush including spring-mounted bristle holders
WO 1992008390 A3
Sammanfattning
A brush (2) including spring-mounted bristle holders (10) in which the springs (16') are formed from a planar strip (12) of elastic material stamped with a plurality of spirally-extending slits at spaced locations underlying each of the bristle holders (10), to define a spirally-extending element integrally formed with the strip (12) and in the same plane as the strip (12). Each of the spirally-extending elements is pressed out of the plane of the strip (12) to produce a helically-extending spring element (16') underlying each of the bristle holders (10) and decreasing in diameter from the strip (12) to the bristle holder (10).
