Title (EN) METHOD AND DEVICE FOR EXTRUDING AND LABELLING A CYLINDRICAL PRODUCT
(FR) PROCÉDÉ ET DISPOSITIF D'EXTRUSION ET D'ÉTIQUETAGE D'UN PRODUIT CYLINDRIQUE
Abstract:
(EN) The method for extruding and labelling a packaging tube comprises the following successive steps: a) forming a partially or totally tubular label (12) from a film in a shaper (20); b) inserting the label into a calibration element (22); c) extruding a tubular body (13) at the concave-face side of the label (12) in an extrusion head (24); d) bringing the outer face of the extruded tubular body into contact with the concave face of the label. In the method, the label (12) comprises at least one layer of which the melting temperature is at least 20°C higher than the melting temperature of the extruded tubular body (13). A first pressure difference is formed in the extruded tube with an air jet. The invention also relates to a device for implementing said method and to a tube obtained by said method.
(FR) Le procédé d'extrusion et d'étiquetage d'un tube d'emballage comprend les étapes successives suivantes: a) formation d'une étiquette (12) partiellement ou totalement tubuiaire à partir d'un film dans un conformateur (20); b) introduction de l'étiquette dans un élément de calibration (22); c) extrusion d'un corps tubuiaire (13) du côté de la face concave de l'étiquette (12) dans une tête d'extrusion (24); d) mise en contact de la face externe du corps tubuiaire extrudé avec la face concave de l'étiquette. Dans le procédé, l'étiquette (12) comprend au moins une couche dont la température de fusion est d'au moins 20°C supérieure à la température de fusion du corps tubuiaire extrudé (13). Une première différence de pression est formée dans le tube extrudé par un jet d'air. L'invention concerne aussi un dispositif pour la mise en œuvre du procédé et un tube obtenu par le procédé.
