ABSTRACT:
A construction for a paper or film cutter for use with strip printers or photo copiers working from continuous rolls of paper or film. It consists of a rotary blade and a stationary blade mounted in a sheet metal U-frame. The rotary blade is driven by a rotary solenoid which provides the inboard bearing for the rotary blade and which is resiliently mounted to the frame to allow for the alignment of the outboard bearing of the rotary blade. The stationary blade is loosely mounted in slots in the U frame. The slots are dimensioned and located to position the cutting edge of the stationary blade to be askew of and to intersect the cutting edge of the rotary blade to provide a cutting point of contact between the two blades. The cutting point of contact traverses the length of the two blades during the cutting stroke. The stationary blade is held in position and the two cutting edges held in contact by the force of a single wire-formed spring applied approximately midway of the length and width of the stationary blade.
