Abstract: The invention relates to a method for the production of a patterned linoleum sheet, comprising the steps: a) application of a non-linoleum material to at least a part of the surface of a green linoleum and/or introduction of a non-linoleum material into given recesses in the green linoleum, or a?) application of a non-linoleum material in the form of a solution, a paste, a suspension or a dispersion onto the scraped linoleum mixture and calendering of the scraped linoleum mixture provided with the non-linoleum material to give a green linoleum, b) cutting the green linoleum thus obtained into pieces of given length, c) overlaying the cut green linoleum pieces to give a tiled stack of sheets and d) calendering the tiled stack of sheets to give a patterned linoleum sheet. The invention further relates to a patterned linoleum sheet obtained by said method and the use thereof.

Abstract: The present invention relates to a floor covering based on linoleum having improved fire-protection properties, comprising at least one wear layer made of linoleum, which contains at least one phosphorus-containing compound, solution, suspension, or dispersion as a liquid/viscous flame retardant in a quantity of up to 20 weight-percent, in relation to the quantity of the wear layer, as well as a method for the manufacture thereof. Furthermore, the present invention relates to a floor covering based on cork having improved flame protection properties, comprising at least one phosphorus-containing compound, solution, suspension, or dispersion as a liquid/viscous flame retardant in a quantity of up to 20 weight-percent, in relation to the quantity of the wear layer.

Abstract: A thermoplastic welding wire for bonding and/or welding flexible planar formations such as floor or wall coverings, in particular linoleum floor or wall coverings, is provided, which comprises at least one polymer based on an ethylene-vinyl acetate copolymer and at least one wax. The welding wire may possibly have shellac or a sheath based on at least one hot-melt adhesive. The welding wire has a high melt-flow index and has a very low soiling tendency.
