    摘要： A sealing machine is disclosed which is useable for sealing products to a backing member, as of cardboard, by covering the products with a transparent cover and by gluing the cover to the backing. Such machine includes plate means adapted to receive and locate a cover into which is placed an article to be packed, said plate means having means to locate a backing, a loading station where the components can either manually or automatically be fed to the cover in the plate means and a sealing station having a movable pressure plate wherein the movable pressure plate is brought into contact with the backing to apply pressure to the backing and the cover while the two are sealed together. The plate means is formed with electrical contacts on the underside thereof which engage depressible electric contact means mounted on the frame at the sealing station whereby electrical heating energy can be supplied to heating element means surrounding the opening in the plate means for the cover when the pressure plate is lowered for completing the sealing operation.

    摘要： A plurality of superposed heat-fusable films are slung about a rotary welding cylinder equipped with a plurality of welding bars effective to produce transverse weld seams at intervals along the length of the films in a continuous operation. A backing cylinder co-operating with the welding cylinder and turning at the same peripheral speed as the welding cylinder is equipped with a plurality of pressure bars effective to exert pressure on the superposed films at the desired locations of the weld seams when the welding bars underlie the pressure bars.
