ABSTRACT:
An apparatus is disclosed for automatically controlling the position of a plurality of slitters for slitting a moving web. A slitter blade and a slitter band are secured respectively to a first and second housing members such that the slitter band cooperates with the slitter blade for slitting the web between the slitter blade and the band. An electronic control is connected to a first and second motor for selectively positioning the blade and band adjacent to each other. The electronic control includes a first and second control module secured to a first and second motor respectively. A digital control computer is connected to the modules for selectively controlling movement of the modules by sending the modules to a designated location using a predetermined number of stepping increments. A monitor is connected to the computer for displaying the position of the slitter blade and the band and a communication bus sequentially conducts control signals from the computer to the modules and sequentially conducts command signals from the modules to the computer for positioning the slitter blade and the band adjacent to each other. A wear detection switch is disposed adjacent the blade for detecting slitter blade wear, the detection switch being electrically connected to the first control module such that when the slitter blade wears, a wear detection signal is generated and conducted from the first module to the computer for compensating for such slitter blade wear.
