Sheeting of abrasives such as emery paper, sandpapers, or abrasive cloth can now be achieved with minimal knife wear with a new specialty sheeter from MAXSON AUTOMATIC MACHINERY COMPANY (Westerly, RI USA). Technological advances include rapid change slitting cartridges, dual knife rotary cutter with clash adjustment, and a pinwheel delivery system that allows for high-speed operation of ream discharge.
Capable of speeds of over 300 cuts per minute on an 11” (279 mm) cut off, the cutter can slit up to 7 piles across the width of the sheeter using inline slitting cartridges. The cartridges share a joint steel base and slide smoothly in or out of the production position on linear bearings and guides. Inline, the slitters can slit high bulk board, paper, or specialty grades. Offline the cartridge’s easy access layout, quick upper and lower knife changes, and precise width settings without shutting down the sheeter.
The cutting section includes knives mounted in upper and lower rotating cylinders. Using the exclusive clash arrangement, the Operator can safely adjust the cross cutting blades while the cutter is running by transversely shifting the upper cylinder across the cutter’s width to increase clash. Quick-lock knife adjustments are used across the upper and lower knife cylinders to allow rapid removal and installation of steel rule blades. With this design, knife changes are completed within 20 minutes.
The delivery and stacking system is designed for high-speed pack discharge of small-format sheet sizes. Sheets are fed into a rotating pinwheel assembly that delivers the clip onto the top of a pile below. A directional gate alters the sheet flow to a second stacking station while a conveyor discharges the completed packs offline.
