ABSTRACT:
An auxiliary wheel device that is used with material handling machines. This is a special compliant urethane wheel for use especially in the corrugated cardboard industry. The wheel relates generally to a transfer mechanism that permits the cardboard and other materials to be transferred from a processing line to accumulation devices such as a stacker and shuttle machine. This improved wheel device has a compliant and flexible surface which permits the cardboard units to be temporarily held in place on the conveyor without damaging or marking the units. The special triangular-like configuration of the apertures molded into the wheel provides an improved strength and durability when compared with other compliant wheels.
