Abstract

A hesitation device is provided in a material conveying roller conveyor system which is simple and inexpensive in construction, while at the same time allows accumulation of conveyed materials with any damaging or disturbing effect upon the conveyed material. This is achieved by providing unbalancing weights in the rollers of the conveyor in the stoppage or hesitation area in combination with a driving belt for the rollers having areas of differing coefficients of friction.
