DF145 shear cut top knife holder is an extremely rugged, high speed pneumatic circular knife holder designed for the paper mill products but it is equally suitable for use on thick gauge materials and most any demanding application. You can cut single or multiple layer paper down to 145mm (5.709 in) widths at web speeds of up to 2,743 m/min (9,000 ft/min). DF-145 shear cut holder incorporates a double shaft guidance system for vibration damping and maximizing top knife holder rigidity which results in cleaner slits and longer circular knife life. A micrometer adjustment device allows for precise depth control setting to ensure the highest slitting quality.
DF145 holder is available with the unique DIENES Constant Side Load lower head design which allows for precise setting of side contact force between the top and bottom circular knives in order to maximize knife life and edge cut quality.
