DIENES’ unique double cylinder pneumatic crush/score cut holder is for heavy duty, narrow-width (½ in) applications. This narrow width slitter develops nearly double the cutting force of single cylinder holders, employs the same mounting dimensions as all the DIENES PQAS style holders and can be interchanged on the same dovetail bars. PQA-MA-HP holders come standard with the same pneumatic connections DIENES offers on all PQAS style holders.
This model is unique in that the pneumatic cylinders are stacked in tandem to deliver high cutting forces. The PQAS-MC-HP holders are able to produce 135 pounds force when 90 PSI is applied to the holder and rated to run up to web speeds of 950 ft/min. This high force knife holder is capable of slitting high strength materials including sand paper, leather, flooring, and roofing materials.
