Spring conveyor apparatus

Device for transferring springs to an assembly machine, wherein the sprints to be transferred are retained in a guide device wherein for the transfer of the springs sliders are provided engaging at the end winds of the springs.

Device for transferring springs to an assembly machine

Described is an electronically regulated coiling apparatus for mattress and upholstery springs comprising essentially a wire draw-in, a wire guidance, a cutting device and a bending device for a wire to be processed, and due to short drive trains equipped with few transfer elements, in particular for the bending device, improved torsional rigidity and flexural strength of the particular drive train is attained. The electronically regulated servomotors used according to the invention can therefore transfer their movement directly onto the bending tools and the drive rollers by interconnecting few transfer elements. This permits bending a wire with decreased tolerances into a corresponding spring.
