ABSTRACT:
A roller for transporting sheet-like material is manufactured by forming a cylindrical resin layer on the periphery of a preheated aluminum pipe, cutting the aluminum pipe covered with the resin layer to a desired size, and joining coaxially oriented shaft end members to both ends of the cut aluminum pipe. The resin layer can be covered on the periphery of the aluminum pipe by use of an extrusion molding machine. A contoured surface on the pipe or an adhesive can help the resin adhere to the pipe. The roller thus manufactured has high stiffness, roundness, less runout and good dimensional stability over a wide temperature range. The weight of the roller is light and maintenance of a rack which is installed with the rollers by the user is easy.
