A method of deep drawing of foam material mold parts made of flat foamed plates, by which the plate which is clamped in a frame is heated on both sides and is sucked against the upper side of a core piece which moves into the plane of the frame, the upper side corresponding to the profile of the mold. The suction takes place with an intermediate placement of a foil, the latter being adhesive material--repelling at least on its interior side. The foil is fastened to the foam material plate by mea...

A composite part of flexible cellular material and elastic, rubber material, wherein the cellular material is a cellular synthetic material and is compressed with the rubber material under cellular synthetic material hot-stamping conditions, the cellular material being condensed in the region of attachment.

An acoustic insulating board of foam with structured bulge-forming surface in the form of regions (I, II) of different thickness. In order to obtain differing acoustic efficiency, the acoustic insulating board comprises plurality of individual boards (1) arranged one above the other, which boards are compressed in the regions (I) of lesser thickness and are fused together on their surface. In the regions (II) of larger thickness, the boards lie loosely on one another so that a top side facing in...

The flap for ventilation ducts, particularly for automobile air-conditioning systems, includes a flap member having opposite surfaces with a predetermined number of openings therein, a longitudinal bottom edge, opposite side edges and an upper edge. A pocket-shaped covering of foam material on the flap member is arranged in two layers which are folded around the longitudinal edge of the flap member onto the opposite surfaces of the foam material including foam sections extending beyond the oppos...

A strip of impregnated and compressed foam material with delayed restoration which is rolled up into a roll, preferably for purposes of sealing, and particularly for improved sealing, the broad side of the roll is provided with a liquid-impermeable layer which adheres to the flank sides of the strip and which is expandable corresponding to the amount of restoration and has a spiral-shaped separation line corresponding to the winding joint of the s

A foam acoustic absorption member having a stabilizing layer with perforations and, in order to obtain a simple, stable structural shape of homogeneous resistance to flow, the stabilizing layer (2) is a wide-side wall of a hollow body (K) which wall is pressed, under thermal deformation, against the foam layer (1), the openings in said hollow body consisting of holes (9) punched from the foam side.

Foam panel with a skin provided on at least one surface and formed by melting of the foam material, characterized in that the skin is covered by a silicone layer.

A package of foam sealing strip of delayed rebound and of foam held in compressed state by the wall of the package. The wall of the package is formed of two flexurally rigid panels which protrude on both sides of the sealing strip and are held together by a plurality of hoops arranged spaced apart from each other.

A foam sealing tape comprises a foam sealing tape layer and an interlayer strip rolled up together in a compressed form. At least one wide-side surface of the interlayer strip has elevations which press into the foam sealing tape layer.

The invention relates to a sealing element for sealing openings in special walls subject to fire-protection requirements, brick wall breaches or the like, wherein for cost-effective manufacturability and processibility and simultaneously fire-protection assurance the sealing element is made of a precompressed strip, preferably impregnated with a chloroparaffin and neoprene base, with delayed restoration, the strip being interspersed with a heat-expanding intumescent compound in an essentially un...
