Abstract: A method and machine for manufacturing brushes, in which bristle bunches are manufactured before being transported to a brush member, the individual bristles being connected to one another. 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 machine for the manufacture of brushes having a bristle collecting station, a melting station, a welding station and at least one bristle bunch holder. The bristle bunch holder consists of a plate having hollow bristle holding sleeves thereon and comprising movement devices, with which the bristle bunch holder is successively aligned with the stations. A discharge station is provided in which ejector means are, during advancement of the bristle bunch holder, pushed through the bristle holding sleeves.

Abstract: A machine for the manufacture of brushes having at least one brush head mounting structure for brush heads. The mounting structure is pivotal about two axes and furthermore is longitudinally movable. The machine comprises a bristle bunch holder for holding bristle bunches and movement devices for guiding the bristle bunch to a brush head. Between the bunch holder and the brush head there is arranged at least two heating elements with contact heating surfaces thereon. The heating elements are provided on a movable heating-element carrier which can be moved between an engaging position, in which one heating surface is adjacent to the brush head and the other adjacent to the bunch holder, and a rest position, which lies outside of the range of movement of the bristle bunch holder.
