<p>With conveyor-type weighers, e.g. for dry bulk goods, the lateral belt guidance presents a problem giving cause to inaccuracy and demanding a relatively large belt and building length. According to the invention, a simple and efficient lateral guidance is achieved by the use of reversing rollers (4,6) which in an interjacent portion (44) is straight cylindrical whilst at the end portions (41) they are arranged with reduced diameters. This conditions a good weighing accuracy and of a considerably reduced belt and building length, which in return makes it realizable in practice to work with belt guide means being freely protruding from a supporting machine chassis (2) such that it is hereby feasible to perform mounting and dismounting work of the belt (10) by means of an overall sideways insertion and removal thereof, a lower tension roller (18) meanwhile being elevated to an locked position. <IMAGE></p> |
