ABSTRACT:
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.
