摘要： A coil spring forming machine for forming a coil spring having a dimensional characteristic, such as a coil diameter and a coil pitch, includes a frame, a control tool movably mounted on the frame, and a control mechanism mounted on the frame and coupled to the control tool. The control mechanism is operable to move the control tool to vary the dimensional characteristic. The control mechanism includes first and second cam surfaces and a cam follower assembly selectively engageable with either of the first and second cam surfaces to vary the dimensional characteristic depending on which cam surface is engaged.

摘要： 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.
