Patent number: 6948348Abstract: 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.Type: GrantFiled: January 5, 2004Date of Patent: September 27, 2005Assignee: Frank L. Wells CompanyInventors: David Scott Wells, George M. Chembakassery, Michael E. Andrea

Publication number: 20020195161Abstract: A coil spring knotting machine including a frame and a camshaft mounted on the frame about an axis fixed relative to the frame. The camshaft supports a support member having thereon a knot-tying member mounted for rotation about an axis movable with respect to the frame. The camshaft also supports a free-wheeling rotating member. The machine further includes a first drive member rotatably driving the camshaft without causing rotation of the rotating member, and a second drive member rotatably driving the rotating member without causing rotation of the camshaft. A linkage connects the rotating member to the knot-tying member to rotate the knot-tying member. Preferably, the linkage includes a flexible member and a movable tensioning member for adjusting the tension in the flexible member.Type: ApplicationFiled: June 20, 2001Publication date: December 26, 2002Applicant: Frank L.
