ABSTRACT:
The specification discloses a conveyor facility including a continuously moving drive belt having upper and lower parts and a plurality of selectively rotatable control elements supported between the upper and lower drive belt parts. Each control element includes a peripheral configuration causing the elements to rotate in a transportation mode and remain stationary in an accumulation mode. Further included are vertically reciprocable pressure rollers for selectively lifting the lower part of the drive belt into engagement with stationary control elements to cause those elements to again rotate.
