A conveyor belt advances the spring pocket (3) in steps, after which the spring (1) is sewn or welded into the pocket. A conveyor (11) feeds the springs from one side to the insertion point (X). The conveyor is movable to a second insertion point (Z). A retainer-finger is positioned beneath the feeder for the length of material and moves in synchronization with the conveyor to and fro between the two insertion points. |
