| 摘要 | Apparatus for making artificial branches, brushes, etc., from a plurality of filaments held between a pair of twisted wires. Comprises a picker device, the peripheral surface of which is advanceable in a predetermined direction. The picker device is adapted to pick up and contain a plurality of separate bundles of filaments, the filaments being disposed transversely of the direction of movement of the surface. The peripheral surface has a continuous slot or space therein, this slot being parallel to the direction of advancement of the peripheral surface. The slot or space is adapted to receive the lower of the pair of wires, which wire extends outwardly from the exit end of the peripheral surface under the filaments. The apparatus further comprises means for feeding a plurality of filaments to the picker device, drive means for advancing the peripheral surface, means for guiding the second or upper wire into position above the lower wire at the exit end of the picker device, independent drive means for advancing these wires, and means for twisting the wires together. | ||||||
| 权利要求 | 1. Apparatus for making artificial branches or brushes from a plurality of filaments, this apparatus comprising: a picker device comprising a flexible endless belt having an upper and a lower reach and being advanceable in a predetermined direction, said endless belt further having a continuous longitudinal space extending in the direction of advancement of said belt for receiving a first strand therein, said belt further having a plurality of spaced apart transverse slots for receiving bundles of filaments therein; a hopper for containing filaments oriented parallel to said transverse slots and having an open lower end in close confronting rerelation to the upper reach of said belt for feeding bundles of filaments to said transverse slots; means for supplying said first strand in a path extending through a preselected portion of said continuous space in the upper reach of said belt and thence away from said belt; first drive means for advancing said belt in said predetermined direction; means for supplying and guiding a second strand to a position above and in spaced parallel relation with the portion of said first strand that is away from said belt; second drive means for moving said strands in the direction of advancement of said upper reach of said belt; and means for twisting said strands together. 2. The apparatus of claim 1, said apparatus additionally comprising means for retaining said filaments in said transverse slots prior to the twisting of said strands. 3. The apparatus of claim 1 wherein said endless belt comprises a pair of endless belts, said belts being parallel to and spaced from one another to thereby define said continuous longitudinal space, the transverse spaced slots of each of said belts being in registry with one another. 4. The apparatus of claim 1, said apparatus further comprising means for varying the relative rate of movement between said belt and said strands. 5. The apparatus of claim 4 wherein said means for varying the relative rate of movement is a means for varying said relative rate to any value within a continuum between zero and a predetermined maximum. 6. The apparatus of claim 4 wherein said endless belt comprises a pair of endless belts, said belts being parallel to and spaced from one another to thereby define said continuous longitudinal space, the transverse spaced slots of each of said belts being in registry with one another. 7. The apparatus of claim 6 wherein said means for varying the relative rate of movement is a means for varying said relative rate to any value within a continuum between zero and a predetermined maximum. |
