Title
(EN) METHOD AND FACILITY FOR CONTINUOUSLY CROSSWINDING GUM STRIPS TO FORM DISCS
(FR) PROCEDE ET INSTALLATION D'ENROULAGE EN CONTINU DE BANDELETTES DE GOMME POUR FORMER DES GALETTES
Abstract
(EN) The method of the invention comprises the following consecutive steps: - continuously feeding out the web (5) from the outlet of the extruder (6) via handling and cooling rollers (7a); continuously depositing the cooled web (5) on a liner (9) that is continuously unwound to form a complex (10); feeding the complex (10) in an accumulator (12); at the outlet of the accumulator (12), cutting the complex (10) into a plurality of strips (2) in the direction of its width; winding, at an initial speed, each strip about a support element (3) to form discs (4); when the discs (4) are completed, stopping the winding of the strips (2) and collecting the complex (10) from the extruder (6) into the accumulator (12).
(FR) Le procédé selon l'invention comprenant des étapes consistant successivement à : - faire défiler en continu la nappe (5) en sortie de l'extrudeuse (6) par l'intermédiaire de rouleaux (7a) de transitique et de refroidissement; - déposer en continu la nappe (5) refroidie sur un film support (9) déroulé en continu pour former un complexe (10); • - faire défiler le complexe (10) dans un accumulateur (12); • - en sortie de l'accumulateur (12), découper le complexe (10) dans sa largeur en une pluralité de bandelettes (2); • - enrouler les bandelettes (2) à une vitesse initiale, chacune autour d'un support (3) pour former des galettes (4); • - lorsque les galettes (4) sont terminées, stopper l'enroulage des bandelettes (2) et faire s'accumuler dans l'accumulateur (12) le complexe (10) en provenance de l'extrudeuse (6).
