Abstract
Abstract The selvage forming device comprises a frame adapted to be connected to a heald of a loom and to guide at least one warp thread. Two superimposed members are rockably mounted in the frame, and an actuating arm is secured to one member for rocking said member, the members being hinged together so that rocking of one member causes the other member to rock in the opposite sense. Each member carries one of a cooperating pair of needles for guiding binding threads, the rocking motion of the members being such as to cause scissors motion of the pair of needles in a plane transverse to the wrap threads. The frame is provided with a plurality of vertical wires under tension for guiding the warp threads.
