ABSTRACT:
A roller having a readily replaceable sleeve so as to allow replacement with a like sleeve and comprising a core with a suitable elastomer layer fixedly secured to the outer peripheral surface thereof and a removable sleeve adapted so as to longitudinally slide onto the core and frictionally engage the outer peripheral surface thereof so as to rotate with the core. The removable sleeve comprises a substantially rigid inner layer for engaging the peripheral outer surface of the elastomer layer of the core and an outer surface layer of a suitable elastomer fixedly secured to the inner layer. The outer surface layer of the core is compressed when engaged by the removable sleeve and imparts a compressive force to the inner surface area of the rigid inner layer thereof so as to maintain the core and the replaceable sleeve in concentric relationship to each other.
