Abstract
Abstract An accumulating conveyor supports transport rollers on a pair of channels with snub rollers below. Adjustable spring means mount the snub rollers. An endless V-belt is trained over the snub rollers and under the transport rollers to be carried by the snub rollers and to actuate the transport rollers. The conveyor is made in sections so that several of these can be attached together, the end transport rollers joined together, and a plurality of units run from a single motor.
