Abstract: The laminate comprises a decorative layer (3), a core layer (4) of resin saturable paper, and an extensible sheet. The extensible sheet is prepared from wood pulp characterized by a basis weight of from about 130g/m 2 to about 505 g/m 2 (about 80 pounds/3,000 ft. 2 to about 310 pounds/3,000 ft. 2 ), a tensile modulus of below 24 N/mm 2 (about 3.5 kpsi) and a cross directional stretch of from about 1 % to about 3 %.
The pulp is refined wood pulp subsequently subjected to a mechanical treatment at an energy input of at least about 0.0394 kWh/kg (about 2 hp-days/ton) which imparts kinking and curling characteristics to individual pulp fibers.

Abstract: In the patented Menser apparatus for saturating a substrate with a liquid saturant, or resin, by conveying the substrate through a resin chamber, the invention improvement is disclosed whereby the apparatus is modified by the installation within the chamber of a separation means, such as a bar, to redefine the path of the substrate through the chamber filled with liquid saturant. Rather than having the substrate pass through the chamber following the path defined by the periphery of the lower portion of the circumferential surface of a mandrel and only being directly contacted by the liquid saturant on one side of the substrate, the redefined path creates a separation of the substrate from said periphery thereby permitting the liquid saturant to contact the substrate on opposing sides to achieve optimum saturation of the substrate by the liquid saturant in volume and uniformity. Inasmuch as the geometric principles which cause an increase in pressure within the chamber as the substrate travels from its entrance into the chamber to its exit, the benefits in saturation provided by such pressure increase are enhanced by the invention as, by the invention modification, they are received on opposing surfaces of the substrate.
