The feed mechanism is for the glued points on a ribbon in a machine binding continuous bundles of tabulator print-outs, having a toothed ring (4) inserting the front part of each point (3) in a hole in the bundle margin (5), while a pair of rollers (6,6') feed the continuous bundles forward and secure the front part below the bottom printed sheet. A pair of rollers (14,14') on horizontal axes one above the other and parallel to the direction of movement of the sheets index the glued ribbon (16) forward from a storage roll (18), being driven by a ratchet mechanism (33,34,35) with cam (30). A head (21) rotates in a vertical plane above the margin holes, and has an eccentric knife (28) and a concentric surface (28') parting off the ribbon and retracting part of the binding. This works opposite a rubber-covered roller (39) lifting the sheets and is rotated in synchronism with movement of the latter and with the ribbon. The roller is also lifted in synchronism with rotation of the head. |
