WESTERLY, RI | Maxson Automatic Machinery Co. offers the SDFK sheeter for a high-impact polystyrene (HIPS) extrusion sheet line. Reportedly, HIPS 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 sheeter.
The cutting section includes knives mounted in an upper and lower rotating cylinders. This cutting action eliminates the skive along the leading and trailing edge on thicknesses to 0.060 in. (1.5 mm) thick, without producing slivers. The operator can safely adjust the cross cutting blades while the cutter is running, by transversely shifting the upper cylinder across the width of the cutter to increase.
Able to run up to 300 fpm (90 mpm), the sheeter follows the extruder’s line speed and with its servo drive system maintains +/- 0.015” (+/- 0.38 mm) cut-off accuracy, company says. Sheeter is equipped with an in-line slitter section that permits multiple pile work across its width, delivering finished sizes that require no secondary trimming.
A reject gate diverts sample sheets or nonconforming material from the stacking station. Using an operator-activated interposing system at the stacker, the in-line configuration allows for nonstop operation while a full pallet of sheeted material is offloaded and an empty skid is raised into position. Sheeter can be mounted on tracks or uses an innovative air float design that allows the equipment to be moved off-line to allow service to the extruder or to allow roll winding of product.
