摘要:
Device and method for holding and feeding weft threads (1, 2) to the gripper (6) of a weaving machine with drives (25, 29) by way of which clamps (11, 12) for the weft threads (1, 2) are moved on movement paths (35, 36) respectively into a feeding position (16, 19), a transfer position (17, 20) and a standby position (18, 21). The movement path (35, 36) of each clamp has a self-contained form. In this case, the start of movement of at least one of the clamps (11, 12) from its standby position (18, 21) into its feeding position (16, 19) takes place in a period which lasts from the start of the beating movement of the reed (9) until the previously introduced weft thread (1, 2) hits the beat-up line (10) of the weaving machine.
摘要:
The invention relates to a device for the intermediate storage of two band-like weft materials (1, 21) for a weaving machine (3), having two storage containers (7, 27) in each of which a U-shaped loop (12, 22) of a weft material (1, 21) can be formed. According to the invention, means (14, 34) for applying tensile forces (15, 35) to the weft material (1, 21) in the inner chamber (9, 29) of the respective storage container (7, 27) are provided. The inner chambers (9, 29) of the two storage containers (7, 27) each turn one of the narrow sides (10, 30) thereof toward each other. Deflection elements (16, 36) are arranged on the storage containers (7, 27) respectively such that the respective weft material (1, 21) can be fed to the inner chamber (9, 29) in a region (17, 37) which is closer to the narrow side (11, 31) of said inner chamber (9, 29) which does not face the inner chamber (9, 29) of the other storage container (7, 27).
