CANADIAN PATENT APPLICATION OF SVEN ARVID RYDEN ULF LENNART AHLSTEDT EDUARD LUSSI FOR METHOD OF MAKING DECORATIVE LAMINATED PRODUCTS SUCH AS TILES, PANELS OR WEBS Abstract of the Disclosure: A laminated decorative tile particularly for floor- ing purposes, is made by forming a base layer of granu- lated cellulosic material in a matrix of fusible plas- tics, and placing on the base layer a thin decorative layer of cellulosic material with natural holes and re- cesses therein. After a film of fusible plastic has been applied on the decorative layer the laminate is hot press- ed and then immediately cooled in a cold press. The tile obtained has a pleasing appearance because the granules of the base layer have been forced up, in the hot press- 1a ing operation, into the holes and recesses of the de- corative layer, filling out these holes and recesses. In this embodiment the tile has a smooth wear resisting layer surface but this surface can be provided with a relief pattern such that it conforms to the structure of the decorative layer, if the tile after cooling is heated in a free state, i.e. without press plates. 1b
