<p>In an apparatus (1) for the manufacture of spring carcasses (2) a coiling station (3) in which springs (5) are manufactured and by means of welding are enclosed in pockets (7) of a heatsealable fabric (6) to form lengths (8) of such pocket springs, and a buffer station (10) for receiving the pocket-spring lengths (8) from the coiling station (3), storing them temporarily and transferring them to an assembly station (25), wherein a number of pocket-spring lengths (8) corresponding to the size of the spring carcass (2) to be manufactured is assembled to form the spring carcass. A transfer station (12) is positioned between the buffer station (10) and the assembly station (25) and includes both a welding and cutting unit (14) in which pocket-spring lengths (8) arriving from the buffer station (10) are welded and cut into the correct longitudinal dimension, and a conveyance unit (22) advancing the cut pocket-spring lengths (8) from the welding and cutting unit (14) to a pick-up position, wherein an assembly unit (24) in turn picks up the pocket-spring lengths one by one in the pick-up position and transfers them to the assembly station (25).</p> |
