Sheeter for High Impact Polystyrene Extrusion Sheet Line

05.10.12MAXSON AUTOMATIC MACHINERY COMPANY (Westerly RI USA) offers a sheeter for high impact polystyrene (HIPS) plastic 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 MAXSON SDFK Sheeter.

In this sheeter design, 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 up to 0.060″ (1.5 mm) thick, without producing slivers.  Using an 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 width of the cutter to increase.  Able to run up to 300 fpm (90 mpm), the SDFK Sheeter follows the extruder’s line speed and with its servo drive system maintain +/- 0.015” (+/- 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 that 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 SDFK Sheeter allows for non stop operation while a full pallet of sheeted material is offloaded and an empty skid is raised into position.

The SDFK Sheeter can be mounted on tracks or use 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.
