Abstract of the Disclosures An apparatus for bonding laminar workpieces has a feed station, a heating and pressing station with two heating zones, and a delivery station with a cooling zone. A lower conveyor belt is driven through the feed station and the heating and pressing station. An upper conveyor belt is driven through the heating and pressing station, and is mounted a sufficient distance above the lower conveyor belt to carry the workpieces therebetween. Pressing rollers are mounted in the heating and pressing station for pressing the heated workpieces moving therethrough. The adhesive between the laminations of the workpieces is heat-activated in the heating zones to bond the laminations of the workpieces. The heated and pressed workpieces are then moved by conveyor belts through a cooling zone to resolidify the adhesive between the laminations of the workpieces. A pair of suction nozzles, each having an elongated aperture, are each mounted adjacent to one side of the conveyor belts. The suction nozzles suck air from the space between the conveyor belts to introduce at least a partial vacuum therein, to facilitate the formation of uniform bonds between the adhesive and the laminations of the workpieces.
