Abstract
A centering device is provided in a spring core mounting machine having at least one pair of clamping jaws for holding together the terminal windings of adjacent helical springs while they are being connected by threading wire helices through them, with the terminal windings of the helical springs being provided at two diametrically oppositely located portions with bent-out zones in which the spring wire extends at least approximately in a straight line and in parallelism with the opposite zone. A slide is provided which is movable in axial direction and which engages the respectively newly supplied spring at its terminal winding and presses it against the movable clamping jaw.
