Abstract
Apparatus for drawing-in warp yarns into the gaps of a weaving reed includes a reed hook (22) for sequentially opening the reed gaps for the insertion of a draw-in member carrying a warp yarn, and a transport system for the stepwise transport of the weaving reed in its longitudinal direction past the reed hook location. The transport system has a first transport member (BW) extending over the length of the weaving reed and coupled to this in the operating state is a gripper-like second transport member (48, 49) for intermittent engagement with the first transport member (BW). As a result of this arrangement, the two functions of reed transport and reed opening are decoupled and can each be optimized independently. This allows the draw-in frequency to be increased. Moreover, the reed hook and reed teeth are given maximum protection.
