Title:
METHOD FOR PRODUCING ROLLER MEMBER, ROLLER-MEMBER MOLD, ROLLER SHAFT, AND ROLLER MEMBER
Document Type and Number:
WIPO Patent Application WO/2016/084333
Kind Code:
A1
Abstract:
A roller shaft is inserted into a mold including molding members respectively having a first mold surface that defines an outer circumference of a roller portion and second and third mold surfaces that respectively define first and second flat portions of the roller portion, and the mold is then closed. A molding material is injected around the roller shaft to integrally mold the roller portion. The roller portion includes the outer circumference and the first and second flat portions rising from the roller shaft to the outer circumference. The roller shaft includes flange portions at portions corresponding to the first and second flat portions. The flange portions prevent the molding material from leaking outside the first and second flat portions when the roller portion is integrally molded around the roller shaft by injection molding.
