MAXSON AUTOMATIC MACHINERY COMPANY (Westerly RI USA) offers an automatic squaring system on its stationary bed knife cutters, or as a retrofit to existing sheeting equipment, relieving the Operator of making that adjustment when setting the cut-off. The design ensures accurate, repeatable positioning is maintained.
An AC servomotor, mounted on a gear head, is coupled to a fine threaded screw. The servomotor is governed by a microprocessor, which mathematically calculates the squareness for the cutoff setting. The servomotor turns the screw, positioning the cutter head accordingly. Sensors set for the minimum and maximum cut-off range prevent over travel.
Squareness of +0.020” (0.508 mm) is maintained. A manual override switch permits the Operator to set the sheet squareness and when returned to automatic mode assigns the manual setting to memory for the given sheet length
