Abstract: A plate-like element for supporting or bearing an object, with a core of generally rectangular shape and composed of a foamed plastic. The core is covered at least on both surfaces by a plastic film of impact-resistant material. A connection of the plastic films, which cover the core on both surfaces, is formed in the region of a peripheral side edge of the core between a surface of the core and an adjoining, peripheral border of the core. A plate-like element which receives a corresponding load can be reliably produced by simple method steps.

Abstract: In the case of a plate-like element (1) for supporting or bearing an object, with a core of generally rectangular shape and composed of a foamed plastic, wherein the core (2) is covered at least on both surfaces (3, 4) by a plastic film (6, 7) of impact-resistant material, it is provided that a connection (9) of the plastic films (6, 7), which cover the core (2) on both surfaces (3, 4), is formed in the region of a peripheral side edge (8) of the core (2) between a surface (3) of the core (2) and an adjoining, peripheral border (5) of the core (2), as a result of which a plate-like element (1) which receives a corresponding load can be reliably produced in simple method steps. Furthermore, a method for producing a plate-like element (1) of this type is provided.

Abstract: A device for multifoaming expandable plastics, such as, for instance, EPS, EPE, EPP or polymer mixtures, includes at least one storage or supply assembly and a foaming vessel for the discontinuous or batchwise afterfoaming of the prefoamed expandable plastics, whereby precisely adjustable bulk densities are attainable in an afterfoaming procedure while observing tight environmental conditions.

Abstract: In a process for multifoaming expandable plastics, such as, for instance, EPS, EPE, EPP or polymer mixtures, with prefoaming being effected in a first step and afterfoaming of already prefoamed material being effected in at least one further step, it is provided that discontinuous or batchwise foaming is carried out as final afterfoaming. A device for multifoaming expandable plastics, such as, for instance, EPS, EPE, EPP or polymer mixtures, includes at least one storage or supply means and a foaming vessel for the discontinuous or batchwise afterfoaming of the prefoamed expandable plastics, whereby precisely adjustable bulk densities are attainable in an afterfoaming procedure while observing tight environmental conditions.
