Abstract
A slip roller conveyor has parallel side walls and a plurality of driven slip roller assemblies mounted therein. Each driven assembly comprises a stub shaft that is threadedly mounted in the side wall and has a wrench-engageable head. A pulley with a sleeve extension is rotatably mounted on the shaft and a slip roller is mounted on the sleeve. The entire driven slip roller assembly is easily removed from its wall mounting by simply engaging the head with a wrench and unscrewing the shaft from its wall mounting. The conveyor drive system includes a positive drive belt having its grooves and teeth intermeshed with mating grooves and teeth on the driven pulleys. A side edge of the belt is guided by the inner surface of the conveyor side wall. A guide strip having an anti-camming surface keeps the drive belt intermeshed with the pulleys along the drive run of the drive belt.
