Abstract

PURPOSE:To manufacture a belt having a high strength to be used in duplicator, etc., by providing spirally a temporarily twisted yarn between pre-vulcanized rubber sheets. CONSTITUTION:A 0.4mm.-thick unvulcanized rubber is covered on a mold, and a temporarily twisted nylon yarn is provided spirally at intervals of 0.5mm. and with a tension force of 20kg in a winding manner on said pre-vulcanized rubber and hot-bonded. Then, a pre-vulcanized rubber is further covered on said temporarily twisted nylon yarn, and they are subjected to vulcanizing treatment to obtain a belt 1.2mm.-thick and 30mm. in width. In this case, the preferred tension force range of the temporarily twisted nylon yarn for winding is 50g or less.
