<p>The present invention relates to a machine for binding sheets together with plastic strips. The machine compresses two strips, one strip (21) having studs extending therefrom and another strip (24) having holes corresponding to the studs, towards each other, then cuts off the ends of each stud and forms rivet heads thereon to bind the sheets together. The improvement over such machines uses a motor (201) to drive linkages previously manually actuated. The binding motor (201) drives linkages (81, 67 and 221, 232) on either side of the machine which causes a transverse pressure bar (61) to apply a pre-selected force on the strips, then to initiate movement of a knife (122) which cuts off the studs and form heads thereon and finally release the compressive force. A second motor (216) drives a linkage (218, 219, 221) which returns the pressure bar to its upward position as the binding cycle is completed.</p> |
