The DF-145 shear cut top knife holder is an extremely rugged, high speed pneumatic circular knife holder designed for the paper mill environment 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 (5.71”) widths at web speeds of up to 2,743 meter per minute (9,000 feet per minute). The DF-145 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.
The DF-145 holder is also 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. The circular top knife holder weighs 16kg (35.3 lbs) and is designed with a 6 mm (0.24”) horizontal side stroke that minimizes setup efforts. Additional features include choice of T-bar or linear bearing mounts, precision cant angle plates, 360 degree blade guard, quick change lower circular knife head, optional Easy-Set tab, optional oil wick, 180mm (7.10”) or 200mm (7.88”) diameter circular blades and a TWO YEAR WARRANTY!
