(EN) APPARATUS FOR GUIDING AND/OR FORMING AN EXTRUDED STRAND OF PLASTIC AND PROCESS FOR COATING A FLAT MATERIAL
(FR) DISPOSITIF POUR LE GUIDAGE ET/OU LE FAÇONNAGE D'UN BOUDIN DE MATIÈRE PLASTIQUE EXTRUDÉ, ET PROCÉDÉ DE REVÊTEMENT D'UN MATÉRIAU PLAT
Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung zum Führen und/oder Formen eines Kunststoffstranges und/oder eines Kunststoffprofiles, vorzugsweise eines Kunststoffrohres, die einen Bereich mit veränderbarem Querschnitt (1) und Mittel (2) zum Verändern des Bereiches mit veränderbarem Querschnitt (1) aufweist, wobei der Bereich mit veränderbarem Querschnitt (1) aus einem gewickelten Flachmaterial oder mehreren Lagen eines oder unterschiedlicher Materialen gebildet wird, wobei das gewickelte Flachmaterial (3) oder die mehreren Lagen eines oder unterschiedlicher Materialen in Teilbereichen überlappt und im überlappenden Bereich (4) eng aneinander liegt. Erfindungsgemäß ist dabei vorgesehen, dass das Flachmaterial mit einer flexiblen und elastisch verformbaren Schicht versehen ist. Weiterhin umfasst die Erfindung ein Verfahren zum Beschichten der Vorrichtung.
(EN)
The invention relates to an apparatus for guiding and/or forming a strand of plastic and/or an extruded plastic section, preferably a plastic pipe, which apparatus has a region of variable cross section (1) and means (2) for varying the region of variable cross section (1), wherein the region of variable cross section (1) is formed from a wound flat material or a plurality of plies of one material or of different materials, wherein the wound flat material (3) or the plurality of plies of one material or of different materials overlaps in partial regions and, in the overlapping region (4), lies in close contact with itself. According to the invention, it is provided that the flat material is provided with a flexible and elastically deformable layer. Furthermore, the invention comprises a process for coating the apparatus.
(FR)
L'invention concerne un dispositif pour le guidage et/ou le façonnage d'un boudin de matière plastique et/ou d'un profilé en matière plastique, de préférence d'un tube en matière plastique, qui présente une zone à section transversale variable (1) et un moyen (2) pour la variation de la zone à section transversale variable (1), ladite zone à section transversale variable (1) étant constituée par un matériau plat enroulé, ou par plusieurs couches d'un matériau ou de matériaux différents, le matériau plat enroulé (3) ou lesdites couches d'un matériau ou de matériaux différents se recouvrant en zones partielles et étant contiguës entre elles dans la zone de recouvrement (4). L'invention est carctérisée en ce que le matériau plat est pourvu d'une couche flexible et élastiquement déformable. L'invention concerne en outre un procédé de revêtement du dispositif.
