  • Electronic stencil cutter
    Patent number: 4330798
    Abstract: An electronic stencil cutter having a rotatable drum with an original subject sheet and a stencil sheet mounted side by side thereon. Scanning and stencil cutting heads are mounted on a common carriage for simultaneous movement along the original and stencil sheets. The original subject sheet is retained in a holder consisting of a flexible, transparent sheet wrapped about the drum, one end of the retainer sheet being held releasably against the drum by a pressure-sensitive adhesive strip. The ends of the stencil sheet are held by an elongated clamp bar in a slot in the drum, the clamp bar being urged outwardly by springs and manually releasable by latch members at the ends of the bar. The stencil cutting head has a plastic stylus which is deflectible by a solenoid to press a wire electrode against the stencil sheet while cutting the stencil. The solenoid has a soft, felt-like nose which engages the stylus to dampen vibration of the electrode.
