Abstract: The barrier seal (2) for use in a conveyor belt (4) installation comprises a wall section (20), a primary seal member (22) and a secondary seal member (24). The respective wall sections (20) are each clamped to the respective side walls (18) by a series of clamping brackets (19). The wall section (20), the primary seal member (22) and the secondary seal member (24) are conveniently moulded in a single unit from a EPDM rubber having a Shore hardness from (65) to (80).

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).

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.

Abstract: A reversible belt steering assembly for centering of conveyor belts which during operation is subjected to a lateral displacement away from a neutral position. A rotating mechanism (3, 19) supports at least one steering roller for the conveyor belt, and is rotatably attached to a first fixed beam (2) for rotation about an axis (a) perpendicular to the conveyor belt. A first set of guide rollers (9) abuts the sides of the conveyor belt, and is thus displaced laterally depending on the lateral displacement of the conveyor belt, and a first transfer mechanism supports the first set of guide rollers (9) for transferring the lateral displacement of the first set of guide rollers (9) to the rotating mechanism (3, 19), to rotate the steering roller to a position where it guides the conveyor belt back to the neutral position. There is a second set of guide rollers (9′) corresponding to the first set of guide rollers, and a second transfer mechanism corresponding to the first transfer mechanism.

Abstract: A belt steering assembly for centering of conveyor belts (5) comprises a mechanism with steering rollers (1) and guide rollers (9). In the event of a lateral misalignment of the belt (5), the belt's movement will be transferred from the guide rollers (9) to the steering rollers (1), with the result that the steering rollers return the belt to a neutral position. Preferred ratios are described between different lengths of a lever arm (6) for transfer of the movement. A method for loading of a conveyor belt comprises moving the conveyor belt (5) laterally before loading to a position where the centre of gravity of the loaded material (15) falls on the conveyor belt's central portion (12), and after loading steering the conveyor belt laterally to its neutral position.
