Abstract

PURPOSE:To form easily a multi-layered roller in which inner layers are firmly adhered to a cored bar by utilizing heat shrinkage of the outer layer, by composing it of the core bar, an organo-macromolecular foamed layer and a non- electrifiable layer. CONSTITUTION:A solution of chemically active composition containing an expanding agent in injected from the gate 10 into a injection mold composed of cylindrical main mold 6, top mold 7 and bottom mold 8, in which a core bar is set. In this mold, thereby, hardening reaction accompanied by foaming is promoted, a foamed layer 5b is formed around the core bar 2 as an axis, and otherwise, a tubular body 3 made by ordinary extrusion is coated with a conductive material and heated in a furnace 13 to form a light-weight seamless non-electrifiable roller in which all layers are firmly adhered together by utilizing the heat shrinkage. The thickness of the foamed layer can be ranged freely from 5mm-7mm and the coefficient of friction (mu) can be varied by selecting the material of the unelectrifiable layer.
