摘要:
The present invention relates to a honeycomb sandwich sheet or panel, based on thermoplastic polypropylene, comprising a structure consisting of two flat outer films, thermowelded to a central film, consisting of a thermoformed blister film, with blisters repeated in a regular and continuous pattern, said flat outer films consisting of a coextruded two-layer film (AB), based on thermoplastic polypropylene, wherein the inner layer (A) faces the central thermoformed film, and the central thermoformed blister film consists of a coextruded three-layer film (ABA), based on thermoplastic polypropylene, wherein the two outer layers (A) face the flat outer films, wherein said structure comprises a further layer C thermowelded to the outer layer B of the two flat outer films.

The present invention relates to a transparent thermally insulating cover element (1), in particular for greenhouse covers, said cover element comprising a main body (10) having two interspaced parallel panel-type elements (5) and at least one edge profile (18, 18a, 19, 19a) running laterally, said profile together with the main body (10) forming at least one cavity (12) which is substantially sealed off from the external atmosphere. The main body (10) is non-positively connected, preferably bonded, to a glass layer (14, 16) by means of one of its outer surfaces (9, 11) facing away from the cavity (12).

Es wird ein Verfahren zum Herstellen von Wellfurnier (5) vorgeschlagen. Um vorteilhafte Verhältnisse zu schaffen, wird vorgeschlagen, das Wellfurnier (5) mit einem Schälmesser (8) mit Wellenschliff und mit einem Gegendruckmesser (10) mit Wellenschliff von einem um die eigene Achse rotierenden Stamm (9) als Wellfurnier (5) abgeschält, und weiterer Folge in der gewellten Form getrocknet wird.
