An apparatus for transferring springs to a spring conveyor comprises a transfer device and an output device. The transfer device is mounted such that it can be moved between a plurality of positions in which the transfer device is respectively configured to receive a spring, and is configured to transport a received spring during movement of the transfer device between the plurality of positions. The output device is configured to selectively output the spring received by the transfer device from the transfer device at one of plural output positions, wherein the plural output positions are pairwise different.

Apparatus and method for transferring springs with transport wheel

A string ( ) of pocketed coil springs ( ) is formed by inserting compressed springs between upper and lower plies of a folded, preferably thermally weldable fabric ( ). The springs are maintaned in a compressed configuration while a longitudinal seam ( ) joins the free edges of the thermally welded fabric ( ) together. Subsequently, the compressed springs ( ) are allowed to relax into an expanded configuration after which a transverse seam ( ) is formed in the fabric ( ) between the adjacent springs ( ) thereby encapsulating each spring ( ) within a fabric pocket ( ). The string ( ) of pocketed coil springs ( ) is advantageously formed without the need for reorienting the springs ( ) after being inserted between the plies ( ) of the fabric ( ) and thereby avoiding the disadvantages and complications associated with turning or reorienting the pocketed coil spring ( ).
