摘要

"Subset of bristle, method of manufacture of subassemblies of bristles and apparatus for formation of subsets of bristles.Apparatus for the formation of sub assemblies includes a vertically oriented bristles that slot, which is formed by two endless belts (52) and (54).A wheel (76) disposed above the slot, pushing a strand of bristles in the direction of the groove. The cord of bristles has a series of bristles connected to a base string in two rows.The rows of bristles can be oriented horizontally, so that all the bristles are co planar in the horizontal plane.Or they may be oriented angular shape with the base cord in the vertex of the angle.When the bristles are pushed in the direction of the groove, they bend to adopt a new orientation substantially parallel.An ultrasonic heater (80) heats the bent bristles to realign the thermoplastic material from which the bristles are manufactured, so that, during cooling.The parallel orientation is maintained.
