Center surface slitter rewinders provide the most flexibility for winding challenging webs to larger diameters. Winding torque is transmitted to the winding shaft like a traditional center driven rewinder, while the wound rolls are also in contact with a driven surface roller or rollers. The torque provided from each driven section can be varied in limitless combinations to yield the desired finished roll quality for a multitude of substrates.
| Maximum Web Width | Maximum Rewind Diameter | Maximum Speed | ||

| CS2 |
86 inches (2185 mm) |
50 inches OD (1270 mm OD) | 2500 fpm (760 mpm) | |
| CS3 | 86 inches (2185 mm) | 50 inches OD (1270 mm OD) | 2500 fpm (760 mpm) | |
| CS4 | 86 inches (2185 mm) | 40” OD and 50” OD (1016 mm OD and 1270 mm OD) | 2500 fpm (760 mpm) | |
Options
Center Surface Slitter Rewinder Options
Shafted Unwind Stand
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 Unwind Stand
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".
Translating Arm Unwind Stand
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
Automatic Knife Positioning System
Available in score, shear (top or top/bottom configuration) or razor for quick and easy positioning
Laser Core Positioning System
Ensure cores align with knife positions saving time and eliminating frustration
Air Differential Shaft
Air differential shafts allow you to convert larger diameter rolls at lower tensions. These shafts produce and maintain precise individual control over multiple winding packages.
Vacuum Trim System
The unique 45º Venturi profile substantial increases air velocity and static pressure provides more efficient trim removal.
Roll Pushers
Linear actuated roll pushers enable the operator to remove the finished rewind packages without repetitive physical force.
Roll Cradle
Model 410 Roll Cradle can be provided to help ease the process of unloading finished rolls. Following the completion of the rewind cycle, the operator will lift the mandrels from the machine to the roll cradle and lock them in place. The 3” and 6” mandrels will be held from the center, allowing the operator to remove the finished packages from both sides of the shaft.

CS1 Slitter RewinderOriginally developed as the model 740, this duplex cantilevered center surface slitter rewinder is ideal for narrow width slitting. Also available as a lift-out.
-
CS2 Slitter RewinderThe CS2 features a shaftless rewinder with trimming capability and minimum gap or contact rewinding capabilities that was originally known as the model 400.
-
CS3 Slitter RewinderBuilt upon the model 220, this simplex shafted rewinder is ideal for trimming and rewinding or bisecting; available in minimum gap or contact rewinding mode.
-
CS4 Slitter RewinderImproving on the already successful model 280 and 800, the CS4 offers unmatched flexibility with an updated new look and increased performance. Ideal for R&D applications or any operation seeking the versatility to accurately slit paper, film, nonwovens or foam up to 86 inches (2185mm) wide with center, center-surface or center winding in minimum gap mode.
