Abstract
A preformed multiturn coupling element of the helical-coil 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. In one embodiment the thread passes through the tape and an overlying filler cord, its loops being drawn half-way around that cord and being interlinked at points between the cord and the tape.
