Mandrel Rubber Sleeves are employed in order to reduce any damage on steel sheeting during the winding process. They be can be used on the payoff reel to change a reel to fit different ID coils. The sleeves can also be used to rewind the reel to wind a sleeve to a different diameter without doing damage to the coil with telescoping and breaks.
Apr 17, 2000 · FIG. 9 is a view in perspective showing the invention in the application of an uncoiler, with the adapter sleeve poised for receipt over the uncoiler mandrel; FIG. 10 is a view similar to that of FIG. 9 showing the adapter sleeve in the operating position over the uncoiler mandrel; Polyurethane Mandrel Un-coiler and Re-coiler Rings Slide-on Sleeves that Increase the Diameter of Un-Coiler and Re-Coiler Mandrels. Constructed of high impact, abrasion resistant polyurethane. 30 shore A to 70 D; Available in segments 1" to 24" wide. In various O.D.'s and I.D.'s; Provides tighter windng of coils; Easier to install and remove than conventional steel overlays; Will not stretch or lose shape
Jun 20, 2019 · 6. The maximum diameter of the expanded mandrel with rubber sleeve is 508mm or 610mm. Technical Parameters Size of steel roll:-- Outer diameter of steel roll:Maximum ofØ 1500mm -- Inner diameter of steel roll:Minimum ofØ 508 -- Width of steel roll:`800-1250mm Maximum steel roll weight:15-25 t Frame and base:Welding low carbon steel US6354534B1 - Mechanism for increasing the diameter of A recoiler/uncoiler for use in a line processing sheet material includes a segmented drum that is expandable from a contracted position to an expanded position. To enable the drum to accommodate coils of sheet material having different internal diameters, a sleeve consisting of sleeve segments which match the segments of the drum is installed on the drum and is expandable and contractible
