  • Patent number: 4082594
    Abstract: A method wherein a machine-foldable wrapper for chewing gum has a paper substrate metallized to give the appearance of continuous foil, the foil being made discontinuous to allow the paper to reach and maintain a moisture content which is in equilibrium with the ambient air. This prevents the wrapper from curling at the edges while in storage.

  • Patent number: 4050971
    Abstract: A device for applying lengths of a heat sealable film over the open ends of cups. The device includes means which engage the end of a supply length of the film which is coiled in a cartridge, pull a predetermined length of the film from the cartridge, move the cup and predetermined length of film into engagement, heat fuse the film to the lip of the cup, and cut the fused length of film from the supply length at the cartridge.

  • Patent number: 4002519
    Abstract: Successive pouches are formed from a web of plastic film by advancing the web through a folding station and folding the web along a longitudinal fold line to form a two-ply portion and a single ply portion adjacent thereto. At a sealing station, confronting surfaces of the two-ply folded portion of the web are sealed together along longitudinally spaced apart seal areas extending transversely across the two-ply portion to define a series of successive pouches interconnected by the seal areas. At a flap forming station predetermined waste areas are severed and removed from the single ply portion of the web to form the same into a series of successive flaps extending alongside each of the pouches and adapted for being folded over the pouches to close the same.

  • Patent number: 3959061
    Abstract: Apparatus and a method for inserting flexible liners into container lids. The apparatus includes a piston and means for actuating the piston in a reciprocal path. Means are provided for supporting a container lid in a position substantially normal to the reciprocal path of the piston at one end thereof. The piston has means affixed to the end of the piston nearest the interposed liner for moving a flexible liner interposed between the piston and the container lid into the container lid and for urging the liner into a flat position within the container lid.

  • Patent number: 3956044
    Abstract: Surgical sponge material is unwound from a spool and fed onto a horizontal support where it is cut to the proper length, folded once by means of a vertically reciprocable mandrel, and held in an upwardly open cavity between the two tines of a rotatable fork. The fork rolls the sponge in a cylindrical portion of the cavity to form the sponge on the tines of the fork. A pusher strips the sponge from the tines of the fork and moves it into a trough where an ultrasonic welding horn seals the free end of the sponge material to prevent it from unraveling. The sponge material is preferably woven from cotton or the like but includes one or more synthetic threads of thermoplastic material to facilitate the ultrasonic welding step.

  • Patent number: 3954934
    Abstract: A method for forming rubber slugs of precisely determined masses. The method embodying the instant invention may be performed utilizing a machine characterized by a stripper unit which serves to extract a continuous, uniformly dimensioned strip of rubber from an endless sheet provided about a roller of a rubber mill, a platen roller, disposed adjacent to the rubber mill and driven at a substantially constant angular velocity, adapted to receive the strip in an adhering relationship for tensioning the extracted strip and a reciprocating knife for transversely severing the tensioned strip into slugs of predetermined lengths, whereby the mass of each of the resulting slugs is precisely determined.

  • Patent number: RE28732
    Abstract: A labeling machine including means for feeding a continuous web having thereon a series of labels of a given length but with certain of the adjacent labels thereon spaced differently than other adjacent labels, and having thereon control elements related to such differences in the label spacing, the machine further including label severing means operable to cut off the terminal labels in the web at their given lengths regardless of the different spacings therebetween, and means controlled by the control elements on the web and operating the severing means to cut from the web the labels in uniform length and without having attached thereto any web portions providing spacings between adjacent labels. .Iadd.
