ABSTRACT:
Rows of springs are periodically supplied to a mattress spring core assembly machine 7 by a transfer system 6. The springs are taken, in turn, from one of two conveyor belt pairs 4, 5 by the transfer system. The individual springs are produced by spring coiling machines 1, 2 with each machine feeding one conveyor belt pair. By periodically shifting the transfer system 6 its gripping arms 20 can alternately take a row of springs from one or the other conveyor belt pair, thus doubling the overall production rate.
