摘要： 1. A double band belt conveyor having an end-less rotating conveyor belt, whose band (2) is supported on troughed roller sets (23) at a belt feeder (9) and connecting with a vertical stretch (19), and is held flat on the vertical stretch, and having an endlessly rotating cover belt (18), whose band (29) can be buckled in the conveying stretch for the formation of closed conveying chambers (30) preferably between external tensioning reinforcements (48) and cooperating, shear-resistant transverse reinforcements (27), whereby the band edges are pressed together and the longitudinal edges of the band are held together, characterised in that for holding together the bands (2, 29) outwardly projecting hooks (35, 36) with opposing openings (37, 38) are provided on both cover belt edges (33, 34), which the longitudinal edges (45, 46) of the conveying band (2) approach on running off the troughed roller sets (10, 11) or from which they move away on running of the conveyor band (2) onto the troughed roller sets (25), and that, beyond the last troughed roller set (11) of the belt feeder (9) in the conveying direction, at least one belt bearing roller or belt guide roller (16, 53) is provided which flattens the conveyor band (2) lying on it, the longitudinal edges (45, 46) of which thereby engage in the hooks (35, 36) which serve for pressing together the band edges and for mutual holding together of the bands (2, 29).

摘要： PCT No. PCT/DE85/00297 Sec. 371 Date Jun. 11, 1986 Sec. 102(e) Date Jun. 11, 1986 PCT Filed Aug. 30, 1985 PCT Pub. No. WO86/01491 PCT Pub. Date Mar. 13, 1986.A twin-belt band conveyor in which the flat belt of an endlessly circulating conveyor band forms a closed conveying space with a belt of a cover band running along therewith on a steep conveying track, the edges of each belt being held in superimposed arrangement by guides along the longitudinal sides of the conveying space, the conveying space (34, 50) being formed by indentations of at least one of the belts between the guide, and opened at the end of the steep track by a deflection of the cover band directed around a turn, and the indented belt being straightened out for its return travel. The cover band belt (2) has tensile reinforcements disposed in its longitudinal sides and transverse reinforcements which cooperate with the tensile reinforcements are provided in the cover band, the indentations and straightened out areas (32 to 34) being formed between the transverse reinforcements and the tensile reinforcements, and the belt of the conveyor band limiting the conveying space is held flat on the steep track and the guides of the upwardly moving belt strands are of continuous design.

摘要： An apparatus for distributing concrete, especially in the shuttering of gallery linings in mining and tunnel workings, comprises a transportable distribution mast carrying an articulated conduit for conveying concrete which is pivoted on a column which can rotate around its axis. The mast comprises a swivel extension forming the end section thereof, and a main boom which connects the column to the swivel extension, the swivel extension being foldable from above onto the main boom. The main boom is divided into several mast sections joined together by power-operated pivotal connections so that the mast is articulatable in a swivel plane containing the column axis, the range of relative pivotal movement between the mast sections being such that the main boom may be extended upwardly and forwardly from the folded position of the mast sections, with the swivel extension in its folded position, the power-operated pivotal connections of the main boom being disposed below the folded swivel extension.
