Abstract: A trimmer to cut a backing on which an overlay is mounted. The trimmer includes cutting blades and a removable fence that has a stop. The fence is carried by a pair of risers that are capable of moving relative to the work surface. A rotatable lever arm is coupled to the risers by a linking cam rod. When the lever arm and linking cam rod are rotated in a first direction, the risers move upwardly from the work surface and the stop of the fence is lifted upwardly and off the work surface to create a gap that enables the backing to move past the fence to the cutting blades to be trimmed. When the lever arm and linking cam rod rotate in an opposite direction, the risers move downwardly toward the work surface, and the stop is lowered against the backing to prevent the overlay from moving to the cutting blades.

Abstract: Apparatus for use with a pair of thermoplastic strips of the type illustrated in U.S. Pat. No. 3,608,117 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.
