摘要： In a loom having a weft thread supply spool at each side thereof and a shuttle whereby thread from each spool is alternately carried across the shed as a U-shaped loop, improved thread guide elements, one on each end of the batten, are actuated in consequence of movement of the batten through each of its reversal positions, at one of which the batten engages the last-laid weft thread to beat up the same and at the other of which the batten begins its return for another beating-up while the shuttle moves through the shed. Each thread guide element comprises a member mounted on the batten for bodily movement therewith and for rocking movement relative thereto. Each such member rocks between a first position wherein a thread eye thereon is located to dispose weft thread extending from its adjacent spool across the shuttle path and a second position wherein the thread eye holds the thread clear of that path. Each member is rocked to its first position upon movement of the batten through its said one reversal position and to its second position upon movement of the batten through its said other reversal position. Rocking is imparted either by the inertia of a weight on the member, due to acceleration and deceleration of the batten incident to reversal of its motion, or by a friction or magnetic retarding device connected between the member and the loom frame.

摘要： A weft thread carrier is disclosed for a loom with a weft thread supply at each side thereof and wherein the carrier, just before entering the shed, engages a weft thread segment that it draws into a loop while moving in the shed. Each weft thread segment extends across the carrier path obliquely to that path, from its supply through a fixed thread eye to the selvedge. The carrier has a hook projecting towards each of its ends, each capable of catching a weft thread segment, but it also has a deflecting surface for each hook, so arranged in relation to its hook that it deflects a thread segment away from the hook if the segment is at one oblique angle to the carrier path but permits the hook to engage a segment at the opposite oblique angle. Hence, as the carrier emerges from each side of the shed it merely deflects the thread segment across its path, but in moving towards the shed its then-forward hook engages the same segment.

摘要翻译： 公开了一种纬纱架，用于在其每侧具有纬纱供应的织机，并且其中载体在进入梭口之前与纬纱线段啮合，纬纱段在梭口中移动时被拉入环中。 每个纬纱线段沿着该路径倾斜穿过承载路径，从其供应通过固定螺纹眼延伸到边缘。 托架具有朝向其每个端部突出的钩子，每个钩子能够抓住纬纱线段，但是它还具有每个钩子的偏转表面，其相对于其钩子布置，使得线段远离钩子偏转，如果 该段与载体路径成一个倾斜的角度，但允许该钩以相反的倾斜角接合一段。 因此，当托架从棚的每一侧出现时，其仅使线段横过其路径偏转，但是当朝向梭子移动时，其向前的钩接合相同的段。
