Abstract: A machine for connecting successive rows of coil springs together into a coil spring assembly. The machine, in preferred form, initially picks up a row of coil springs by inserting a pick up finger into the barrel of each coil and moving the springs onto a support platen. In the course of transporting the coils between pick up and the support platen, 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 reciprocable compression bar. Thereafter, and through use of rotatable transfer fingers on a transfer shaft, the springs are removed from under the compression bar, and are moved into clamping dies. Leading rotary transfer fingers on the transfer shaft first pull the row of springs out from under the compression bar, and trailing rotary fingers then push the springs into the downstream one of upper and lower clamping dies.
