摘要： A weft filament is inserted as a pick in a weft direction into a shed formed between groups of warp filaments extending and generally traveling in a warp direction, and is beaten into the warp filaments by a comb to form a woven textile. A defective pick is removed from the warp filaments by a system comprising at least one stripping nozzle directed generally upstream in the warp direction and connected to a supply that feeds compressed gas to the nozzle so the gas is expelled therefrom as a jet directed generally upstream in the warp direction over the defective pick to dislodge same from the warp filaments. The defective pick is then withdrawn in the weft direction from the shed after it is dislodged from the warp filaments by the nozzle.

摘要： A shuttleless loom has a pair of inserters each having a head provided with a respective weft-yarn gripper and movable from respective sides of a warp therethrough to an advanced position in a central warp region with a weft yarn held in the gripper of a one of the inserters and a mechanism effective on the grippers in the central region to open the gripper of the one inserter and thereby transfer the yarn held thereby to the gripper of the other inserter so that the other inserter can pull the weft yarn the rest of the way through the warp. A support and guide system for the inserters has respective guide and support elements in the central region for the inserters laterally and longitudinally engaging same and forming at least one support surface positioned underneath the head of the respective inserter, and respective deflectors on the elements for spreading the warp at the support surfaces so that the warp does not come between the heads and the respective support surfaces.
摘要翻译：无梭织机具有一对插入器，每个插入器具有设置有各自的纬纱夹持器的头部，并且可以从经线的相应侧部通过其延伸到中心经纱区域中的前进位置，并且纬纱保持在夹持器中的一个插入器和在中心区域上的夹具上有效的机构，以打开一个插入器的夹持器，从而将由此保持的纱线转移到另一个插入器的夹持器，使得另一个插入器可以以其余的方式拉动纬纱通过翘曲。用于插入器的支撑和引导系统在中心区域中具有相应的引导和支撑元件，用于插入器横向和纵向地接合插入器，并形成位于相应插入器的头部下方的至少一个支撑表面，以及用于扩展的元件上的各个偏转器在支撑表面处的翘曲，使得翘曲不会落在头部和相应的支撑表面之间。
