Abstract
Plastic binding strips, one strip having studs which fit through holes in sheets to be bound, the other strip having holes to receive the studs are bound in a machine which compresses the strips toward each other, then cuts of excess stud length and forms rivet heads on the stud ends to bind the strips together. The present improvement over such machines uses a motor to drive linkages previously manually actuated. The binding motor drives linkages on either side of the machine which cause a transverse pressure bar to apply a pre-selected compressive force on the strips, then to initiate the movement of the knives which cut off the studs and form heads thereon and finally release the compressive force. The cutting and head forming functions are performed by springs which pull a transverse rod rearward of the machine to push rearward a support for the knives. A second motor drives a linkage which returns the pressure bar to its upward position as the binding cycle is completed.
