摘要

A machine is described for cutting large diameter wound logs of paper or similar web material such as toilet tissue and the like into relatively small discs for use specially in institutional dispensers. The machine includes a cradle and transport means (5) for inserting a large diameter log (B) of paper into a gripper (23) which holds the log securely and stationary while a band saw (7) cuts the discs of paper from the log. The gripper (23) includes a ring through which the log passes, said ring including a plurality of radially movable plungers which support and retain the log within the ring while the band saw is cutting a disc from the log. The mechanism also includes an automatic guide and sharpening station for maintaining the sharpness of the band saw and, furthermore, includes a support and discharge mechanism for removing the discs of paper from the gripper.
