In surface slitter winding, the torque necessary to wind the material is imparted to the outside of the winding roll as it is in contact with a driven roller or set of rollers. As nip loading is essential to this winding method, it should not be used for materials that are sensitive to being nipped. Surface slitting machines are ideal for materials such as paper, nonwovens, textiles, and specialty composites that can be wound to large diameters using this type of machine.
The DS2 offers the ability to slit large paper and nonwoven materials. Expanding on the original model 909, the DS2 is engineered to slit large rolls at higher speeds.
Dusenbery shafted, frame mounted are offered in two configurations, standard or floor pickup in 40", 50" or 60" max. roll diameters, max. web width of 75" and max. roll weight of 2,500 Ibs.
Pivoting arm unwinds are shaftless floor pickup stands available in 48" and 72" max. roll diameter for larger roll weighing upwards of 8,000 Ibs. with web widths of 100".
Dusenbery translating arm unwinds are shaftless floor pickup stands available in 48" and 72", ideally suited for high output, high performance applications, max. web widths of 100" and max. roll weights of 10,000 Ibs
Neatly join two web ends together with pneumatic clamps or vacuum suction
Available in score, shear (top or top/bottom configuration) or razor for quick and easy positioning
The unique 45º Venturi profile substantial increases air velocity and static pressure provides more efficient trim removal.
Following a run cycle, the doffing assembly will eject the finished rolls from the winding position onto the hydraulically powered tilting unload table. Under operator control, the table will tilt, lowering the finished rolls.
Shaft extractor provides a means to remove shafts from finished packages.
