ABSTRACT:
A process for the manufacture of bristle products, from multifilament bristle strands wound in the form of endless material onto reels. The bristle strands, after unwinding, are supplied to a processing station, where they are fixed to a bristle carrier either in continuous or cut to size form. The removal from the spools takes place by a holding or tensile force acting in timed manner on the bristle strands at the processing station. In order to eliminate the non-uniform lengths of the individual monofilaments due to manufacture or processing and which lead to loop formation during processing, at least during the holding cycles acting on the processing station, a tensile force directed counter to the holding force acts on all the bristle strands. This tensile force is set in such a way that the bristle strands and, preferably, also all the monofilaments within a bristle strand are stretched between the spools and the processing station.
