Abstract

A cover belt conveyor with a basic belt guided by three support rollers (9) arranged in a trough-shaped pattern. To guarantee the ability of such a cover belt conveyor to function at different amounts of material to be conveyed, four pressure rollers (11) are arranged over the entire width of the cover belt (3) in the case of a basic belt (2) with a troughed support roller station comprising three support rollers (9) such that the two middle pressure rollers (11a) always act on the area opposite the middle roller (9) and the two outer pressure rollers (11b) of the cover belt (3) act on the area opposite the two oblique support rollers (9). The pressure rollers (11) are arranged individually pivotably on the frame of the conveyor and they can thus automatically adapt themselves to the particular volume of material to be conveyed between zero and a maximum and apply the necessary pressure on the cover belt (3) in the process. Two inner and two outer pressure rollers (11a and 11b) are always arranged alternatingly in the direction of conveying.
