Title: Wall panelling of wood lamellae coupled into reeled sheet - supported by a plastic film substrate
IPC: B27D1/04
Filed: 1973-06-26
Abstract: Continuous flexible sheet is made by bonding together longitudinally and laterally small rectangular wooden lamellae to give the appearance of a massive structure. For stocking and installing wall covering materials in large panels with genuine timber colouring and textures without having to use broad timbers.

Such strips may be assembled side by side by colamination on to a support film, pref. using an interfacial adhesive. The laminate should be consolidated by calendering and then linished until the timer lamellae are thin enough to be reeled.
