  • Patent number: 5443678
    Abstract: The process relates to the production of a product consisting of a substrate to which an adhesive with long-term effect and a protective band are attached to permit use of the adhesive to be deferred. The process is characterized by the use of a substrate whose surface to which the adhesive is attached may present irregularities. The adhesive is heated to a temperature at which is becomes paste-like and almost liquid, and is brought to an opening situated above a plane surface on which the substrate has been placed. The adhesive is then caused to flow simultaneously with a relative movement between the substrate and the opening. This results in the adhesive being deposited on the substrate as a strand that is preferably continuous. The temperature of the adhesive is then lowered in order to increase its viscosity until it becomes paste-like to the point of turning solid.

  • Patent number: 5139597
    Abstract: A distinct conveyor assembly allows a business form sealer--such as a pressure sealer--to operate with forms that have been detached from a continuous supply. Individual forms are detached from the continuous supply while being conveyed in a first direction, to form shingled forms having irregularly positioned side edges. The forms are deshingled by conveying them from the detacher at high speed (e.g. an increase in speed of about ten times or more), and they are registered while being conveyed in the first direction at high speed. Registration may take place by moving the forms against one side edge, or moving them between funnelled side edges to ultimately engage straight guides on both side edges. After registration, the forms may be fed directly to the sealer, or into the top of a hopper, and then withdrawn from the bottom of the hopper and passed through a folder before being fed to the sealer.

  • Patent number: 4859266
    Abstract: A method and apparatus for powder sewing two plies of cloth or fabric material by spraying an adhesive powder onto one side of one ply of cloth or fabric from a powder spray gun having a corona discharge electrode mounted thereon. A second pin electrode is provided on the opposite side of the one ply of cloth or fabric. Electrical charges of differing polarity are applied to the electrodes while the cloth or fabric material is moved between the two and powder is sprayed thereon. In the course of migrating through the electrostatic field created between the two electrodes, the powder is caused to follow the force lines created within that field and to migrate onto one side of fabric in the form of a long, narrow band of powder. A second ply of cloth or fabric is then positioned over the first ply and over the band of powder. Pressure and heat applied to the powder activates the powder and causes it to become tacky so that when subsequently cooled, it adheres the two plies together along the narrow powder band.

  • Patent number: 4850948
    Abstract: A laminated package insert is provided having increased compressive strength for a given weight of board stock, and being easier to erect, as compared to previously known inserts. The insert is made from two substantially identical blanks, with identical score patterns, placed face-to-face and adhered in selected areas, leaving other areas adhesive-free. The score lines are formed so that no score line has to be broken backwards during erection, thereby making erection easier, particularly for automatic insert erecting equipment. A method and apparatus for assembling the insert are also provided wherein two feeders alternately feed blanks into a hopper, each successive pair of blands being face-to-face, one blank having adhesive on selected areas of the face facing the other blank. The synchronization of the two feeders is carefully controlled, as is the settling of the blanks in the hopper, using air jets free of turbulence.
