摘要

A preformed multiturn coupling element of the helicalcoil or meander type is juxtaposed with a tape and a loop is formed by a stitching thread whose needle is thrust upwardly between each pair of turns. A gripper engages the loop and draws it laterally out of the coupling element to reintroduce it between another pair of turns where it is engaged by another loop thrust through the tape.
