Summary:PROBLEM TO BE SOLVED: To provide a method of manufacturing a toothed belt which can enhance productivity by forming an exact tooth portion by shaping, and can narrow the belt width by increasing a core wire density. SOLUTION: The toothed belt is manufactured in the following manner. A reinforcing fabric 6 is pinched between a toothed forming mold 1 having a tooth-like portion 4 and a groove-like portion 5 arranged alternately and a pinion roll 7 mating with the tooth-like portion 4 and the groove-like portion 5, and is shaped by synchronously rotating the toothed forming mold 1 and the pinion roll 7. A rubber sheet 10 for the tooth portion is wound around the toothed forming mold 1, and both the cut surfaces are butt-jointed. After a non-sticky material 15 is wound around the surface of the rubber sheet 10 for the tooth portion, the rubber sheet 10 for the tooth portion is heated, pressed and cast in the groove-like portion 5 so that it does not remain on the top surface of the tooth-like portion 4 of the toothed forming mold 1. A core wire 21 is wound around the surface from which the non-sticky material 15 was removed, a rubber sheet 22 for the back portion is wound around and is vulcanized. The belt sleeve released from the mold is cut into a predetermined width. COPYRIGHT: (C)2005,JPO&NCIPI
