Bias cut device and V-belt manufacturing method

摘要

PROBLEM TO BE SOLVED: To provide a bias cut device that enables grinding of a bias cut surface simultaneously with bias cutting of a belt and to provide a manufacturing method for a V-belt.;SOLUTION: A bias cut device comprises: a drive shaft 21 and a driven shaft 22 around which, while tension is applied to a belt 40 containing short fiber 16, a belt can be wound in a direction of a circumferential length of the be a motor 24 that is able to rotate and drive the drive shaft 21; a first diamond wire saw 51 and a second diamond wire saw 52 arranged in a space along the outer perimeter of the belt 40 wound between the drive shaft 21 and the driven shaft 22; a first wire saw unit 41 and a second wire saw unit 42 by which the first diamond wire saw 51 and the second diamond wire saw 52 are freely moved in a direction in which these saws obliquely enter with respect to a portion, wound around the drive shaft 21, of the belt 40 moved in a circle between the drive shaft 21 and the driven shaft 22.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
