ABSTRACT:
Wreath ring making machine having a ram torque stabilizer and an angle plate for imparting an offset angle to one rib arm. The wreath ring has a circular spine and C-shaped ribs disposed about the spine, the ribs having a back and two arms. The machine includes a pneumatic cylinder having a central axis connected to a ram, which is connected to a female die, which moves against a male die. A frame running parallel to the cylinder axis has the cylinder attached at the distal end and the male die attached at the proximal end. The stabilizer includes a stabilizer bracket attached at an intermediate portion of the frame and a corresponding stabilizer follower attached to the ram, where the stabilizer follower is slidably received by the stabilizer bracket, and stabilizes against torque in the ram and cylinder. The stabilizer significantly reduces torque on the cylinder and the resulting maintenance. The angle plate is attached to an inside face of the female die, which forces the corresponding rib arm to assume an angle offset relative to the opposite arm.
