摘要：
The present invention provides an improved gripper for a folding cylinder of a folding machine. Each gripper is independently actuated and includes a gripper member and cam follower arm having their own springs to provide a gripping force and to allow it to operate separately from other gripper members on the same folding cylinder. The force to open the gripper prior to the material to be folded being tucked into the folding cylinder opening is generated by the involute profile on the cam arm which pushes against the involute profile on each gripper member. Independently actuated grippers provide the advantage that the folding operation is not susceptible to material thickness variations and it is possible to fold materials with a different thickness on different lanes of a web folding machine.
