ABSTRACT:
Apparatus for use with a pair of thermoplastic strips of the type illustrated in U.S. Pat. No. 3,608,177 wherein one strip is formed with studs longitudinally spaced at intervals and a second strip apertured and counterbored at the same intervals is used to bind sheets apertured at the same intervals at locations spaced inward from one marginal edge is described. A pressure bar is first manually moved to operative position and a handle compresses the strips together by exerting a controlled force on the pressure bar. The handle then initiates movement of a support for a knife consisting of a length of metallic ribbon material having spaced horizontal stretches in horizontal alignment with excess stud lengths of the first strip projecting through the second strip, the ribbon being under tension to hold such stretches taut. As the support moves toward the studs a current is passed through the ribbon, heating it so that the ribbon functions to cut off the excess stud length slightly below the second strip. The current then is terminated as the support moves upward forming heads on the stud stubs filling the counterbores in the second strip. By this time, the ribbon has cooled and functions to cool and harden the heads. Retraction of the handle returns the support to initial position and releases the pressure bar. The handle also actuates a punch for the apertures in the sheets, the punch being located at a different station in the machine from the binding mechanisms.
