FIELD: conveyers. SUBSTANCE: belt conveyer has endless conveyer belt 4 which envelops the conveyed material. The belt has central part 5 and two side parts 6 and 7 connected with the central part. Besides, the belt conveyer has frame with bearing rollers designed to support the conveyer belt at least in a portion of its trajectory. Side part 6 of belt 4 is divided into two sections near to its free longitudinal edge to form longitudinal pocket, which is open in the direction of free longitudinal edge. Free side portion of second side part 7 enters the pocket so that actually it cannot be turned in the pocket and is forced to remain in the pocket due to connection of side parts with the central part. Installed on the frame is rotary disk 15, which narrows in the direction of its periphery in the form of wedge so that it comes in contact with the pocket and widens the latter to provide a possibility for introducing free portion of second side part 7 into the pocket. EFFECT: improved reliability and efficiency of conveyer operation. 12 cl, 6 dwgi
