Abstract

A collision-proof spring transfer takes place in the process, which comprises a continuous transfer of coil springs from the pipeline through an exit opening of the pipeline into assigned spring receptacles, and an automatic prevention of any re-entry of coil springs that have passed through the exit opening in the direction of the spring receptacle and rebound from the region of the spring receptacle back into the pipeline.
