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 The other tamping member is withdrawn and moved backwards prior to reintroduction into the magazine above the freshly admitted batch.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.

Abstract: This invention relates to new and useful brush making apparatus which allows the manufacture of a wide variety of different type brush constructions having flared tufts. The apparatus is capable of picking, trimming and assembling all the synthetic filament tufts required in a tufted brush construction simultaneously and fusing the tufts at different angles from one another onto a separate substrate. The apparatus comprises a filament stock box for dispensing cut-to-length synthetic filament, a new and improved picking element containing movable means for changing the parallel attitude of at least two adjacent picker tubes, melting means for fusing one end of the synthetic filament, and mounting means for attaching fused filament ends onto a substrate.

Abstract: This invention relates to new and useful brush making apparatus which allows the manufacture of a wide variety of different types of constructions having pretrimmed synthetic filament units. The apparatus is capable of picking and trimming all the synthetic filament required in a single tufted construction simultaneously and simultaneously assembling said filament into said construction. The apparatus comprises a filament stock box for dispensing cut-to-length synthetic filament, a new and improved picking element containing trimming and internal wedge means, which when inserted into the stock box will pick and trim the desired construction, and means for fusing the end of the picked construction and for mounting the prefused end thereof to form a filament construction.
