Each of the chain conveyor's running rollers(12) supporting the chain has a groove(15) on its periphery and which conforms to the rounding of the running rails(13,14). Two additional rails(16,17) constructed the same as the two first rails are inserted in the support element(2) and below the first rails, and are for guiding of the running rollers of the lower chain strand(1.2). At least one support piece per chain strand may be replaced by a round brush comprising a ring with bristles fitted on it. |
