PURPOSE:To prevent a belt from such trouble as skew, deviation and slip by fitting the belt at both ends with a flexible and resilient guide rail having a fitting mouth. CONSTITUTION:Each guide rail A is made of a flexible and resilient material and equipped with an upper jaw 1, a lower jaw 2 having a ridge 3 longitudinal and a fitting mouth 4 for belt situated in the middle. The belt B fitted with such guide rails A at both ends is borne by a carrier 9, each of whose ends constituted a grooved roller 8 pressed by another respective roller 10. On the letan side, the belt B is borne by a roller 11 and pressed by a pair of grooved guide rollers 12. The pulley at the front and rear of the machine overall length is provided with grooves at both ends. This constitution should well prevent the belt from skew, deviation, slip and turnover by blast. This is also applicable to any belt device of conventional type.
