Rack And Pinion Shuttle Motions Patents (Class 139/23)
  • Patent number: 7644737
    Abstract: A velvet ribbon with double-sided nap is produced by weaving three superimposed webs (8, 10, 12) connected to each other by nap threads (14). The nap threads (14) of the above triple web are separated between the middle web (8) and a first web (10) in a first cutting device (36, 36a). In a second cutting device (46, 46a) the nap threads between the middle web (8) and the second web (12) are separated to give the middle web as a double-sided velvet ribbon (8). The corresponding ribbon weaving machine (2) comprises three superimposed weaving points (31) each with a weft introduction body and a common shedding device (16). A first cutting device (36) for cutting the nap threads (14a) between the middle web (8) and a first web (12) and a second cutting device (46) for cutting the nap threads (14b) between the middle web (8) and the second web (10) are provided afterwards. The velvet ribbon (8) produced thus has a nap (56, 58) on both sides.

  • Patent number: 7451787
    Abstract: The weft introduction needle for a ribbon needle loom comprises a bent arm (20), which may be fixed at one end (22) to a drive element (24) of a ribbon needle loom and comprises a hook (28) at the other end (26), for registering an exposed thread loop. The arm (20) is provided with a guide piece (30) essentially over the whole length thereof, forming a longitudinal slot (32) with the arm (20) for accommodating at least one weft thread. At the end away from the hook (28), the guide piece is connected to the arm (20), by means of a connector piece (34). A guidance element (36) is arranged on the side of the arm (20) facing away from the guide piece (30) in order to improve the guiding of a weft thread loop, extending over only a section of the length of the arm, starting from the vicinity of the hook (28), whereby the guidance element (36) forms a diverter point (35) in the region away from the hook (28), for diverting the free flare (38) of the weft thread loop (6).
