A dual knife rotary sheeter equipped with productivity enhancement features is available to converters and printers of board grades from Maxson Automatic Machinery (Westerly RI USA). The sheeter’s low inertia knife cylinders allow high speed on short cut offs, yet permits knife loading up to 1000 pounds/3300 ft2 (800 grams/meter2). Speeds of up to 1300 fpm (396 mpm) can be achieved on machines up to 90” (2286 mm) wide.
Two shaftless self loading roll stands cradle rolls weighing up to 10,000 lbs. (4545 kg) in position while the sheeter is running. The overhead automatic splicing system, joins the end of one roll to the beginning of the other while the sheeter speed exceeds 800 fpm (240 mpm), eliminating down time associated with roll changes.
Using the sheeter’s “continuous run” feature and rapid pallet discharge system maximizes production by removing a full skid and inserting an empty pallet while the operation continues, without the loss of any acceptable sheets.
