ABSTRACT:
A roller type of conveyor including a support and a plurality of rollers rotatably mounted on the support for moving items therealong. A slip pulley is piloted on and rotatable relative to the rollers, and a drive mechanism and a drive belt are operative relative to the slip pulley for rotating the rollers up to a desired point of resistance by the rollers, to thus provide an accumulating type of conveyor. Tension members are in contact with the drive belt for adjusting the drive pressure and thus the accumulation feature of the rollers, and a brake is also operative on the rollers for interrupting rotation and it is under the control of mechanism and sensors, all being related to the item accumulation feature.
