(FR) DISPOSITIF D'ÉCARTEMENT AINSI QUE PROCÉDÉ POUR L'ÉCARTEMENT D’UNE BANDE DE MATÉRIAU PLANE, ROULEAU ÉLARGISSEUR ET UTILISATION D’UN ÉLÉMENT D'ÉCARTEMENT INDIVIDUEL DANS UN TEL ROULEAU ÉLARGISSEUR
Abstract
(DE)
Die Erfindung betrifft eine Spreizeinrichtung zum Spreizen einer flächigen Materialbahn mit einer Spreizhauptrichtung, mit einem elastisch verformbaren Trägerteil zum Anordnen an einem Rotationskörper und mit einer Vielzahl an elastisch verformbaren Einzelspreizelementen zum Erzielen einer in Spreizhauptrichtung gerichteten Spreizwirkung, bei welcher das jeweilige Einzelspreizelement einerseits an seinem dem Trägerteil abgewandten freien Ende einen Kontaktflächenbereich mit einer Kontaktfläche zum Wechselwirken mit der flächigen Materialbahn aufweist und andererseits an seinem dem freien Ende abgewandten, zweiten Ende an dem Trägerteil angeordnet ist, wobei die Spreizeinrichtung derart eingerichtet ist, dass das jeweilige Einzelspreizelement mittels Fliehkräfteeinwirkung zumindest bereichsweise oder zur Gänze in Richtung des freien Endes kippbar ist.
(EN)
The invention relates to a spreading device for spreading a flat material web with a main spreading direction, comprising an elastically deformable support part for arranging on a rotational body and comprising a plurality of elastically deformable individual spreading elements for achieving a spreading effect oriented in the main spreading direction, wherein each individual spreading element has a contact surface region with a contact surface for interacting with the flat material web on the individual spreading element free end facing away from the support part, and the second end facing away from the free end is arranged on the support part. The spreading device is designed such that each individual spreading element can be tilted at least partly or completely in the direction of the free end under the effect of centrifugal forces.
(FR)
L’invention concerne un dispositif d'écartement pour l'écartement d’une bande de matériau plane comprenant une direction d'écartement principale, une partie support pour la disposition dans un corps de rotation et une pluralité d'éléments d'écartement individuels élastiquement déformables pour l’obtention d’un effet d'écartement orienté dans la direction d'écartement principale, l'élément d'écartement individuel respectif présentant d’une part, à son extrémité libre opposée à la partie support, une surface de contact pour interagir avec la bande de matériau plane et étant disposé d’autre part, à sa deuxième extrémité opposée à l’extremite libre, sur la partie support, le dispositif d'écartement étant configuré de telle façon que l'élément d'écartement individuel respectif peut être basculé au moins partiellement ou dans sa totalité en direction de l’extremite libre par l’action de forces centrifuges.
