Automatic paper sheet cutting for laser printer-plotter - obtaining data regarding lengthwise cutting from plotter, and using sensor for transverse markings and processor contg. memory and converter to activate cutter

摘要

The sheets are cut according to markings on the conveyor corresp. to the cross-section of the sheet. A control unit (64) with an electronic memory and a converter picks up the information concerning the format to be cut. This information is lengthwise cutting data from the plotter (1). When the control unit receives and processes the signals, the cutting device is activated. A digital counter is provided so that the length cutter is only activated after a predetermined number of pulses. This ensures that the length cutting takes place only after cross-section or width cutting. Light barriers (10,12) connected to the control unit detect the start (10) and end (12) of the paper. USE/ADVANTAGE - For plotter or laser printer. Simple and secure coding for length cutting device.
