ABSTRACT:
The outlet of a magazine for a supply of parallel bristles in a bursh making machine is adjacent to an oscillatable element which transfers compacted tufts of bristles to an inserting tool. The supply of bristles in the magazine is compacted by one or more reciprocable tamping members which compact the bristles during movement toward the outlet. Fresh bristles can be admitted in unconfined condition or in the form of bundles containing batches of parallel bristles confined in tubular envelopes. The envelopes are opened and removed not later than in the magazine and the released bristles are immediately compacted by one of the tamping members which urges the bristles against the other tamping member which continues to compress the remnant of the supply. The other tamping member is withdrawn and moved backwards prior to reintroduction into the magazine above the freshly admitted batch. The tamping members can bypass each other in the magazine. If the bundles form a chain, the foremost bundle whose envelope is still intact applies pressure against the trailing end of the column of bristles in the magazine to urge the leader of the column against the transfer element.
