Claims7
A fixing apparatus for electrostatographic reproduction or digital printing comprising a fuser member having an outside diameter of 4 to 10 inches, which fuser member comprises:
- (a) a thermally conductive core comprising aluminum or copper and an elastomeric coating and (b) a stainless steel gudgeon that is friction welded to said core, the gudgeon comprising means for reducing heat transfer through the gudgeon during use and for enabling engagement for welding, and in locking engagement with (c) an insulating sleeve.
A fuser member having an outside diameter of 4 to 10 inches for electrostatographic reproduction or digital printing comprising:
- (a) a thermally conductive core comprising aluminum or copper and an elastomeric coating, and (b) stainless steel gudgeon, made from molded powder metal or from cast or machined bar stock, that is friction welded to said core, which gudgeon comprises a shoulder having means for reducing heat transfer through the gudgeon during use, enabling engagement for welding, and providing locking engagement with (c) an insulating sleeve.
A method of making a fuser member having an outside diameter of 4 to 10 inches, which method comprises the steps of:
- providing a thermally conductive core comprising aluminum or copper and an elastomeric coating,
- friction welding a stainless steel gudgeon to the core, the gudgeon having a shoulder with means for reducing heat transfer through the gudgeon during use and for engagement during welding;
- and
- engaging the means with projections in an insulating sleeve thereby locking together the gudgeon and sleeve.
