Abstract: A wood flooring product for assembly into a wood floor is disclosed. The flooring product includes a top, decorative layer, an intermediate layer bonded to the top layer, and a base layer bonded to the intermediate layer. The top, intermediate and base layers are bonded in registration to define a laminated elongate wood flooring strip. A tongue and a groove are formed on respective side edges of the flooring strip.

Abstract: This disclosure describes a press fabric for use on papermaking and similar machines. The fabric is of the open-ended variety, and has loops at each end enabling it to be closed into endless form during installation on the machine by means of a pin seam. The machine-direction (MD) yarns, from which the loops are formed during the flat or endless weaving of the fabric, are coated multifilaments. The coating, either permanent, semi-permanent, or soluble, gives the multifilament a monofilament-like structure enabling good loop formation and stability. The use of multifilament yarn provides a fabric having improved elasticity in the machine direction, and a greater degree of compressibility, following the removal of a soluble coating material, than can be obtained using monofilament yarn.
