DRS-4000 Differential Rewinding Shafts

More Info
Spacerless Design
Clutch/friction rings lock slit rolls in place
Slipping occurs internally on central shaft – no spacers between slits, so core dust and core damage are minimized.
Large Diameter Central Shaft
(e.g. 60mm ø for 3” shaft)
Higher load capacity and faster critical speed.
Various Friction Strips
Accommodate low, medium, and high tension applications.
Ball Type Friction Rings
Easier to load empty cores and unload slit rolls off of shaft.
Double E air shafts are available in steel, aluminum, or lightweight carbon fiber.
 
They replace heavy steel shafts without sacrificing strength or stiffness.
 
DRS-4000 Differential Rewind Shafts

Double E Differential Rewind Shafts ensure the highest winding quality even when rewinding very narrow rolls - down to a half inch in width. By maintaining proper tension on all rolls throughout the winding operation, material doesn’t sag, stretch, or tear. Consequently, the Double E differential rewind shafts improve productivity and profitability.

The Differential Rewind Problem

Differences in material thickness and winding tension often arise when rewinding foils, laminates, plastics, and other materials. These variations can result in different lengths and tension requirements when rewinding smaller rolls on the same rewind shaft. After only a few winding rotations the center of some small rolls may be
too tight while others may show sagging, making the quality of the end product unacceptable.
