  • Paper/plastic composite sheet and method of manufacturing
    Patent number: 5443923
    Abstract: The invention provides a multilayer plastic sheet of self-rollable material comprising at least two layers of material joined to one another at states of different relative stretch and capable of alternating between a relaxed and a tensioned state and of inherently assuming a rolled-up configuration in said relaxed state as a result of the different states of stretch of the respective layers and to retain said inherent property of spontaneous rolling up even after prolonged exposure to sunlight and heat.
    Type: Grant
    Filed: October 14, 1992
    Date of Patent: August 22, 1995
    Assignee: Roll-Screens, Inc.
    Inventors: Josephe Laniado, Moshe Har-El

  • Sunblind
    Patent number: 4848437
    Abstract: The invention provides a sunblind comprising a sheet of rollable fibrous or plastic material capable of alternating between a relaxed and a tensioned state. The sunblind material is pretreated to inherently assume a rolled up configuration in its relaxed state. The blind contains material which interferes with at least a substantial portion of solar radiation impinging thereon in its tensioned unrolled state.
