  • Powered roller conveyor
    Patent number: 4088224
    Abstract: Parallel rollers of a roller conveyor are divided into discrete groups and progressively rotated by groups in a sequential manner whereby a load may be caused to continuously move along the conveyor. The first roller of a group of rollers starts rotating before the last roller of a previous group stops rotating. The total number of rollers which are rotatably driven at any given time is substantially less than the total number of rollers.
