ABSTRACT:
A conveyor has an endless belt spanned over upstream and downstream rollers and having upper and lower stretches. The belt has an outer surface adapted to carry a load in the upper stretch and a lower surface turned inward. Permanent magnets are fixed to the inner surface of the belt and a linear-motor stator is provided underneath the upper stretch and juxtaposed with the permanent magnets thereof. The stator and magnets together form a linear motor for advancing the upper stretch downstream. An array of such permanent magnets is imbedded in the lower surface of the belt spaced apart to permit the belt to flex.
