ABSTRACT:
Continuous forms (e.g. computer paper with individual sheets separated by perforations) of one job are automatically folded and separated from the forms of the next job. Detectable marks are printed within a window onto the first form of one job, or the last of another, in a first mode, or the forms are counted in a second mode. The marks within the window are sensed by an LED sensor, which feeds information to a computer (microprocessor) control. The computer control effects operation of a cutting blade to sever the last form of one job from the first form of the next. The forms are automatically folded in a festooning action by a Bunch folder. Hall effect sensors are mounted for cooperation with notched discs on the same shaft as beaters of the Bunch folder, and function as end of travel limit switches for the folder swing chute, to provide relevant data to the microprocessor for proper operation of the cutting blade.
