Abstract
PURPOSE: To perform a molding of a belt in dimensions as specified only with one metal mold despite a shrinkage rate of its material, by parallelly providing ridges of a V-shaped cross section in the circumferential direction and circumferentially embedding reinforcement cores along a pitch direction of the ridges in the base parts of said ridges.
CONSTITUTION: A plurality of ridges 2 of a V-shaped cross section are parallelly provided in the circumferential direction, and in the base part 3 of each ridge 2 along a pitch direction (arrow mark P) of the, reinforcement cores 4 like fiber glass with a very little or zero shrinkage rate are circummferentially (arrow mark Q) embedded at an interval apart to construct a ridge belt 1. Its manufacturing method is such that on an inner metal mold 7 a tension durable reinforcement core 5 is wound, and on its top the reinforcement core 4 is additionally attached along the axial direction of the metal mold, then placed in an outer metal mold 8 to pour a molding material 9, form a cylindrical body, further cut this into an annular shape finally to obtain the ridge belt 1. In this way, shrinkage of the cylindrical body at its mold releasing can be suppressed to perform a molding in a dimension as determined.
