Abstract
A spring transfer apparatus, shown generally at 10, is positioned adjacent a spring coiling machine 12 (shown only schematically). The transfer apparatus comprises a conveying substrate in the form of a belt 14 arranged in an endless loop and driven in a direction A by a motor 16. The belt comprises a plurality of magnetic spring holders 18 which are arranged in use to accept steel wire springs 20 from the coiling machine 12. Each of the magnetic spring holders has a pair of ferro-magnets 18a for holding the steel springs. The magnets are arranged such that identical poles are adjacent. The apparatus is arranged such that the magnets begin to attract the formed springs before they are cut from the length of wire by the spring coiling machine.
