Abstract (en)
[origin: EP0633337A1] The invention relates to an assembly for the take-up and feed of the weft on a positive-transfer weaving machine, using insertion members, such as lances or bands, equipped with grippers, with exchange in the middle of the forming fabric. The gripper which feeds the weft (2) to the exchange point comprises, in addition to a main device (3, 4, 5) for clamping the weft, a weft-retention device (7) located on the same side as the main clamping device. The retention device (7) comprises two levers (11, 12) mounted pivotably in the same plane along respective transverse axes (6, 17) and describing simultaneous and opposed pivoting movements by means of a suitable mechanical connection (19, 20), in order to offer a wide passage for the weft (2) in the open position, whilst holding it effectively in the closed position. This gripper is used particularly for very coarse wefts or wefts consisting of fancy thread. <IMAGE>
