Abstract: A cleaning device for a conveyor belt for installation essentially transverse to the longitudinal direction of the conveyor belt. The cleaning device comprises a supporting structure (3) adapted to hold the cleaning device in place transverse to the conveyor belt (2), the cleaning device covering essentially the whole width of the conveyor belt (2) and consisting of a plurality of individual scraper segments (1?), each of which consists of a body having a scraping face (4), which scraping face (4) rests against the conveyor belt (2). The scraping face (4) on each of the segments (1?) is elastically connected to the supporting structure (3), the number of segments (1?) is relatively great and all the segments are covered by a flexible material.

Abstract: A conveyor belt aligning device (1) comprising a support frame (2) mounted on a support beam (3) and being substantially horizontal pivotable about a first axis (4), the support frame (2) comprising a frame formed by a cross member 96) and a lever arm (8) extending from the cross member (6); at least one conveyor belt support roller (10) mounted on the cross member (6); a guide roller (14, 15) mounted on a transverse beam that is pivotably mounted on the lever arm (8); the transverse beam (16) being pivotable about a second axis (18); a stay member (20) extending between the support beam (3) and the transverse beam (16). The conveyor belt aligning device further comprising adjusting means for adjusting the distance (19) between the first axis (14) and the second axis (18) and adjusting means for adjusting the distance between the second axis (18) and a central axis (26) of rotation of the guide roller (14, 15).

Abstract: The present invention relates to a belt guidance unit for centring a conveyor belt, which during operation is susceptible to lateral displacement away from a neutral position in its longitudinal direction. According to the invention the belt guidance unit can be employed on conveyor belts that move in one direction as well as in two opposite directions with only very slight alterations and the basic constructional features of the belt guidance unit are substantially identical in the two operational situations.

Abstract: The actuator device for use in a bi-directional conveyor belt comprises a toothed wheel which rotates depending on the belt's transport direction and is engaged with a toothed rack on a toothed element which is movable between two extreme points and which has at each end portion a pin which, when a force is applied in the direction of the end of the toothed element, is arranged to move to a position in which it forms a tooth as an extension of the toothed rack, and when a force is applied in the direction of the opposite end of the toothed element is arranged to move to a retracted, yielding position relative to the toothed rack.
