  • Patent number: 3957554
    Abstract: A method for attaching plastic nets to non-woven blankets without use of adhesives is disclosed. The net is positioned adjacent the non-woven blanket and then the strands of the netting are vibrated causing surface fibers of the blanket to surround the strands and hold the net to the blanket without the use of adhesives.

  • Patent number: 3956542
    Abstract: A multiple ply wood article having a first wood veneer ply defining a generally tubular shape, which may be generally cylindrical, with a pair of confronting ends providing a first seam. A second wood veneer ply defining a generally tubular shape generally similar to the shape of the first wood veneer ply with a pair of confronting ends providing a second seam. The second wood veneer ply being disposed exteriorly of the first wood veneer ply in general surface to surface adjacency. The grain orientations of the first and second wood veneer plies being oriented generally parallel with respect to each other. Adhesive means securing the wood veneer plies to establish a multiple ply tubular body. The first and second seams are preferably in generally relative nonaligned position. Additional wood veneer plies having similar structural features may be secured over the first two plies. Closure elements may be secured to one or both ends of the tubular body in order to establish a container.

  • Patent number: 3953638
    Abstract: A multi-ply absorbent wiping product having a relatively inextensible center ply bonded to highly extensible outer plies to provide superior wet bulk caliper and impression, wet strength and absorption characteristics. The central ply is comprised of wet strength, cellulosic tissue paper having less than about 10 percent stretch. Both sides of the central ply are imprinted with a suitable polymer resin in a regulated pattern covering between about 15 and about 55 percent of the total surface on each side of the central ply. An outer ply of wet strength, highly extensible, creped cellulosic tissue paper is adhered to each of the opposite surfaces of the central ply by feeding the layers between the nip of a pair of synchronously driven, hard-surfaced embossing rolls having a mating pattern of embossments thereon.

  • Patent number: 3953640
    Abstract: An inflatable hollow belt which is longitudinally self shapeable, includes a woven body having warps on one side of lesser length and greater overall strength than the warps on the other side, and an interwoven weft so that the deflated belt can be compactly collapsed and the inflated belt curves along its length. The belt is produced by weaving the hollow belt with the warps along one side having a relatively high heat shrinkage, and then applying heat to the belt to shrink such warps. The wefts and the longer warps are of sufficient strength to withstand the inflation pressure.

  • Patent number: 3934064
    Abstract: Extensible structures are made by partially embedding a selected knitted glass fabric into a perhalopolyfluoroethylene polymer resin sheet. The embedding can be done by pressing the glass fabric into one surface of the sheet heated to a temperature at which it is soft. The resultant composite structure is thermoformable into such shapes as a dished head. The exposed surface of the glass fabric can be impregnated with a castable material useful for such purposes as adhering the composite structure to a substrate such as a metal surface or for reinforcing the composite structure. The composite structure instead of being thermoformed can be rolled and seamwelded into a cylinder shape which can be used as a cylindrical tank lining or as a duct.
