Computaslit Automatic Knife Positioning

Automatic knife positioning is available on new equipment supplied by Universal Converting Equipment or as an upgrade to existing slitting equipment from a range of manufacturers. An analysis has shown that during a job change on a slitting machine, most of the time lost is due to positioning the knives, moving core chucks and aligning cores. Universal now offer solutions to eliminate most of this downtime.

Universal Converting Equipment can offer automatic knife positioning for both razor slitting and shear slitting. The most popular Computaslit system is for setting shear knives due to the time taken to set up male and female knives. The system is controlled by a touch screen operator interface. If the job has been run previously, the operator can recall the setting from the recipe memory, otherwise they enter the slit widths required and the system does the rest. The required positions for the knives are calculated and an electric actuator moves the knives precisely into position. Once in position they are locked securely in place. The system works well with both shaft mounted and dovetail mounted knives.

We have standard Computaslit systems that can be retro-fitted onto a range of machines including Titan, Atlas, Dusenbery, Elite, Cameron and Ashe slitting machines. When combined with a Converter Guide 3 Digital web guiding system, Computacore™ core alignment system, and full differential shafts, a changeover which may have taken one hour can be completed in less than five minutes.
