ABSTRACT:
A perforated web separator for separating a web of paper or forms which include a tractor feed strip. The tractor feed strips provide a plurality of holes that are used to control movement of the web through the separator in order that the web is separated at the desired, predetermined perforations. Sensors count the passage of holes in the tractor feed strips. An interface including analog-digital and digital-analog conversion blocks cooperates with the sensors and a central processing unit to control the perforated web separator. One pair of sensors is provided to transmit and receive horizontally across the moving web to sense a web jam.
