摘要：A machine for connecting successive rows of coil springs together into a coilspring assembly. The machine, in preferred form, initially picks up a row of coil springs byinserting a pick up finger into the barrel of each coil and moving the springs onto asupport platen. In the course of transporting the coils between pick up and the supportplaten, the pick up fingers change the spacing of the coils. The springs are then
compressed against the support platen to a desired height through use of a reciprocablecompression bar. Thereafter, and through use of rotatable transfer fingers on a transfershaft, the springs are removed from under the compression bar, and are moved intoclamping dies. Leading rotary transfer fingers on the transfer shaft first pull the row ofsprings out from under the compression bar, and trailing rotary fingers then push thesprings into the downstream one of upper and lower clamping dies. If a leading row ofcoil springs are already present in the clamping dies, the rows of clamping dies clamptogether the upper and lower end loops of the leading and trailing rows of coil springs.The rows of springs are then connected together by helical lacing wires while clampedbetween the clamping dies.
