A process for the continuous production of a sheeting of stratified material from synthetic resin foam particles especially particles of crosslinking polyethylene includes the steps of scattering foam particles onto a conveying means, preheating the foam particles during conveyance, superficially to a temperature in the range between 100.degree. and 160.degree. C.; thereafter feeding the thus-preheated foam particles to means defining a free falling zone; causing the preheated particle to free-fall within said zone; further heating the particles during falling, to a temperature of at least 200.degree. C., and, at the end of the free fall, piling up the particles on a support surface; compacting the piled-up particles into a sheet-like layer on said surface; and sizing the preliminarily compacted sheet with simultaneous cooling.

A floor mat is formed essentially of cross-linked polyolefin foam for the lining of the floor interiors of motor vehicles. This mat includes a cross-linked polyolefin foam floor mat base having at least one preselected surface area covered with a permanently applied floor-protecting surface layer. The layer is made up of cross-linked polyolefin foam layer and a thermoplastic polymeric film which is heatable in a high-frequency electrical field in dielectric fashion and which exhibits wear resistance superior to the cross-linked polyolefin foam or base. The cross-linked polyolefin foam base is preshaped to conform to the contours of the floor interior of a motor vehicle.

Floor mat, especially for motor vehicles

An engine hood lining for automotive vehicles has a continuous sheet-like body that is formed of a closed-cell polyethylene foam material and is shaped to fit the inside contour of a hood of the vehicle.

Engine hood lining for automotive vehicles

An adhesive interior or dome lining is provided for the interior of a vehicle roof with the central portion of the dome lining being adhesively secured to the roof while free edges of the dome lining are inserted into the gap formed between the roof and the interior roof strut. A profiled member of a soft foam material is provided adjacent the gap with the free end of the dome lining passing over the profiled member to be clampingly engaged into the gap by the compressive forces of the foam material. A method for installing this arrangement is further provided.

Automobile roof interior linings and method of installation

A self-supporting interior lining or vehicle dome having in the edge zones thereof at least one clamping or mounting bead adapted to cooperate with at least one undercut provided in the vehicle roof structure to mount the same thereon. At least one of the clamping bead and vehicle dome or a portion thereof is manufactured of an elastic material to facilitate installation within the vehicle.

Automotive vehicle-dome

An interior covering for automotive vehicles, containers, or the like, which is insulating and optionally constructed to be self-supporting, comprising at least two sheets of polyethylene foam of identical or different density permanently bonded together with a reinforcing polymer-containing layer to form a multiple-layered structure.

Interior covering with reinforcement

A process for the production of multiple-layer sheets, panels, shaped articles, or the like laminates having at least one layer of polyurethane foam material wherein at least one side of the polyurethane foam layer is bonded under the action of heat to a layer of cross-linked polyethylene foam material.

Production of multiple-layer sheets, panels, shaped articles

A process and apparatus for continuous production of molded sheets of a foamed thermoplastic synthetic resin, wherein a synthetic resin is fed into a screw extruder and a low boiling point liquid expanding agent is introduced under high pressure into the extruder and admixed with the resin in the extruder and thereafter the resulting admixture is extruded in the form of a plurality of foam filaments to insure proper distribution of the admixture to the nozzles of the extruder. A gear pump is provided for each nozzle. Also, to avoid collapsing of the foam means are provided for tempering the foam filaments by the application of heat.
