Abstract: The present invention relates to a method and an apparatus for producing a brush. In accordance with said method, a strand of a single filament or of a bundle of filaments is unwound from a spool and moved past a cutting means in which a predetermined length piece of the strand is cut off. Subsequently, said length piece is connected to a bristle carrier. In order to increase the productivity, the present invention suggests that, when the strand or rather the length piece has been cut to length, it should be transported by means of an airflow. The risk that a filament kinks during transport of the strand can be excluded in this way. The apparatus according to the present invention comprises, in a manner known per se, at least one spool keeping a strand of a single filament or of a filament bundle ready for use.

Bristle bunches which are prepared in this manner are distributed by a distributor block to plural tubular conduits leading to a bristle bunch holder which holds the bristle bunches in a desired orientation relative to the brush member. The bristle bunches and the brush member are welded together by pressing them against one another, both the bristle bunches and the brush member having previously been softened at the welding regions. The tubular conduits can be of any desired length and can be routed in any desired direction to the brush member, which permits the manufacture of all brush shapes.

Abstract: A method and an apparatus for joining plastic brush bristles with plastic brush backs provides for heating the tips of brush bristle strands until they are soft and heating zones of the plastic brush backs to which the bristles will be mounted until they are soft. Thereafter, the soft tips of the bristles are brought into contact with the soft zones of the brush backs to fuse the bristles to the brush backs. In the particular structure and method of the machine of this invention, two relatively movable plates alternately clamp to and unclamp from indeterminant-length bristle strands to jog the strand ends into contact with the brush backs. One of the plates carries a cutting blade which cuts the strands into bristle lengths once their tips are fastened to the brush backs.
