Maxson Sheeter Suited for High-Pressure Laminates

WESTERLY, RI | Maxson Automatic Machinery Company reports high-pressure laminate (HPL) manufacturers can increase the productivity and reduce the waste of their sheet lines by replacing conventional drop shear equipment with the dual-knife rotary technology of the SDFK sheeter

High-pressure laminate is composed of layers of kraft paper, a single layer of decorative paper with a solid color or design, and finished with a protective layer that can have printed design accents or other decorative features. Because of the multilayer construction, cut quality to avoid "crumbing' of the multilayer edges is critical, company says.

The dual-knife rotary cutting action eliminates the skive along the leading and trailing edge on thicknesses to 0.125 in. (3.2 mm) thick, without producing slivers. Using an exclusive clash adjustment, operator can adjust the cross cutting blades safely while the cutter is running, by transversely shifting the upper cylinder across the width of the cutter to increase the knife clash, cleaning any fuzziness of the cross cut.

Able to run to 300 fpm (90 mpm), the sheeter can follow the treater’s line speed, and with its servo drive system, reportedly maintains ±0.015 in. (±0.38 mm) cut-off accuracy. Equipped with an in-line slitter section that permits multiple pile work across the sheeter’s width, the SDFK delivers finished sizes said to require no secondary trimming.

A reject gate diverts sample sheets or non-conforming material from the stacking station. Using an operator-activated interposing system at the stacker, the inline configuration of the sheeter allows for nonstop operation while a full pallet of sheeted material is offloaded and an empty skid is raised into position.
