Abstract
An apparatus for forming bristle sub-assemblies includes a vertically oriented slot, which is formed by two endless belts. A wheel disposed above the slot pushes a bristle string into the slot. The bristle string has a plurality of bristles connected to a base string in two rows. The bristle rows can be horizontally oriented, so that all of the bristles are co-planar in a horizontal plane, or they can be angularly oriented with the base string at the vertex of the angle. When the bristles are pushed into the slot, they bend to adopt a new, substantially parallel orientation. An ultrasonic heater heats the bent bristles to re-set the thermoplastic material from which the bristles are made so that after cooling, the parallel orientation is maintained.
