Abstract: A conveyor apparatus for trays or the like comprising a framework for supporting a conveyor path along which the trays are to be conveyed; the framework having side rails for aligning the trays in a uniform orientation along the path of the apparatus; a plurality of freely rotating rollers mounted on the framework between the side rails; the rollers being mounted on the framework in serial spaced relationship such that the uppermost tangential surfaces of successive rollers lie in a continuous plane defining a support surface for the trays; a plurality of wheels mounted to the framework between the rails, the wheels having whiskers protruding from the circumference thereof; the whiskers being bendable from a position in which the whiskers normally protrude from the wheels and resiliently reformable back to the position in which the whiskers normally protrude; the wheels being mounted serially along the length of the conveyor path and between the rollers such that the whiskers extend above the continuous plane
