ABSTRACT:
Product-supporting trays are carried in closed circuit paths by an endless chain engaged with gear members with parallel horizontal axes. Products are extracted from transverse ends of the trays by a pusher which moves parallel to the gear axes and onto an oven hearth located laterally of the discharging station. A tray guide maintains the trays at horizontal orientations at all times. An inner chain guide bears against pins on the chain along their entire continuous paths. The inner chain guide has at least one adjustable part which is movable when the distance between the gear members is adjusted. The pusher has an arm which is perpendicular to the gear axes, and the pusher is slidably mounted on a horizontal guide positioned outside the path of the trays and parallel to the gear axes. The method of operation involves the movement of the pusher parallel to the gear axes from a position outside the path of the trays to a position in the path of the trays and behind the path of a product on a tray close to the discharging station. The tray is moved vertically from its position close to the discharging station to a position at the discharging station until the pusher is laterally behind the product, and the pusher is then displaced parallel to the gear axes to push the product from a transverse end of the tray.
