Abstract
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.
