A foldable foam mat has a longitudinal fold line extending over the entire length of the foam mat and a plurality of transverse fold lines which are arranged in pairs and extend, perpendicular to the longitudinal fold line, over half of the mat toward the edges of the mat. One of each of the transverse fold lines, which are arranged in pairs, is configured as a single fold line, and one as a double fold line. Preferably, the fold lines have an asymmetric configuration, referring to the cross section of the foam mat.

The invention describes a weatherable, plasticizer-free, uncrosslinked, and deep-drawable sheet, especially for the internal outfitting and external outfitting of automotive vehicles, as well as a process for its production, containing 65-25% by weight of a partially crystalline ethylene-propylene-diene terpolymer and 35-75% by weight of a homo- and/or copolymer of propylene, 0-10% by weight of fillers, as well as stabilizers and lubricants, the extruded or calendered sheet exhibiting a tensile strength at break in the longitudinal direction of at least 20 N/mm.sup.2. An advantageous further development of the invention comprises a composite sheet of EPDM/PP sheet with a crosslinked polyolefin foam layer.

Multi-ply weatherable plasticizer-free sheet

A multilayer composite sheet, especially for use as a padding layer underneath artificial grass, or turf includes a bottom layer of expanded synthetic resin, particularly of closed-cell polyethylene foam, and a metallic foil flatly bonded to the foam material. The multilayer composite sheet exhibits low weight per unit area, low water absorption, and low thermal linear expansion suitable for exposure to ambient weather conditions especially sunlight.

The invention describes a multi-ply, self-adhesive and deep-drawable protective sheet, especially for the internal and external outfitting of automotive vehicles, consisting of a carrier sheet containing a thermoplastic synthetic resin based on an ethylene-propylene-diene terpolymer and/or an ethylene-propylene copolymer and a homo- and/or copolymer of propylene, small amounts of fillers and conventional additives; a pressure-sensitive adhesive layer based on an alkyl acrylate and/or methacrylate and/or a copolymerizable, ethylenically unsaturated monomer, such as acylic acid, and a cover layer of a unilaterally siliconized polyolefin film.

Multi-ply self-adhesive and deep-drawable protective sheet, especially

A process for producing an expanded or foamed polyolefin panel with a decorative surface wherein a polyolefin or a mixture of a polyolefin with rubber and/or a synthetic resin miscible therewith is blended homogeneously with a crosslinking agent and a blowing agent and shaped into a panel-like matrix below the decomposition temperature of the blowing agent and the activation temperature of the crosslinking agent; a film of a thermoplastic synthetic resin, imprinted in accordance with a pattern with printing ink on one surface side, is applied unilaterally or bilaterally to the matrix, with the imprinted surface side facing the matrix; and then the matrix, with the film applied, is crosslinked and expanded by heating to a temperature above the activation of the crosslinking agent and the decomposition temperature of the blowing agent.

Mat for sports and athletics with a core layer made of an elastic foam material provided on the topside with a skin-compatible top material, for example, artificial leather or a textile material, and on the underside with a skidproof layer, wherein the side rims of the mat, starting with the core layer to the underside are continuously beveled, especially at 45.degree., and the top material is equipped with a border corresponding especially to twice the thickness of the mat and projecting beyond the topside, and wherein on the inside of the projecting border two especially equal-sized, wedge-like ridges are arranged so that they extend in parallel to the side of the mat in side-by-side relationship. These ridges have the cross-section of an isosceles right triangle and a height corresponding to half the thickness of the mat and are made of an elastic foam material. The projecting borders of the top material are extended with the ridges over the lateral surfaces to the underside of the mat, and the joint gaps are sealed, for example, by cementing or welding to provide a lateral border along the periphery of the mat.

Mat for sports and athletics

A hammock having a mat portion and loop-shaped arrangement at the head and foot ends of the mat portion to accommodate mounting dowels, said mat portion comprising an elastic crosslinked synthetic resin foam sheet, reinforced with a flat textile layer or organic and/or inorganic fibers, threads, strips, or the like, said sheet having a tensile strength of at least 0.20 N/mm.sup.2, a tear propagation resistance of at least 1.0 N/mm, and an ultimate elongation of at least 80%, with a gross density of about 30-130, preferably 30-80 kg/m.sup.3.

Hammock

A continuous composite sheet material is formed of a genuine wood sheet bonded by a layer of adhesive to a thermally weldable, thermoplastic synthetic resin carrier sheet. This composite sheet is especially useful as a covering for a profiled structure used in furniture construction or interior decoration.
