ABSTRACT:
A spring coil assembly having a first row of coils arranged in a first spacing pattern and a second row of coils adjacent the first row and arranged in a second spacing pattern that is different from the first spacing pattern. The spring coil assembly can be assembled using an apparatus comprising a main conveyor adapted to convey a plurality of coils along an axis, an assembler which is operable to intertwine a plurality of coils into a spring coil assembly, and a transfer station operable to move a plurality of coils from the main conveyor into the assembler. The transfer station includes a plurality of pusher arms each of which include a gripper which is operable to grasp an individual coil, a carriage supporting the gripper arms and means for shifting the carriage axially relative to the axis so that a plurality of coils carried by the gripper arms are displaced in the direction of travel of the conveyor.
