ABSTRACT:
A system for limiting maximum material speed for predetermined board length in a corrugator cut-off machine provides an output pulse for each increment of material movement. A divide circuit is connected to the pulse generating means and there are a plurality of gates, with each gate being placed in a predetermined condition for a predetermined range of board length. A counting circuit is connected to the gates and to the pulse generating means. The counting circuit compares material movement with a predetermined maximum speed for each range of board length and when material speed is greater than the predetermined speed, an output signal is provided which may be used to reduce the speed to a predetermined safe speed or to sound an alarm.
