Title (EN) METHOD IN WINDING OF A WEB
(FR) PROCEDE D'ENROULEMENT D'UNE BANDE CONTINUE
Abstract: front page image
(EN)A method of winding of a web, wherein the roll (11) that is being formed is supported in the direction of the axis of the roll by means of a first (12) and a second (13) support member placed at both sides of the roll. In the method, the shape of the end of the roll that is being formed is measured by means of indirect or direct measurement, and the relative positions of the support members in relation to one another are regulated based on the measurement. As indirect measurement, it is possible to measure forces (20) in the axial direction of the roll, and as direct measurement, it is possible to measure the side line of a roll end directly by means of contact measurement or contact-free measurement. Based on the measurements, the relative positions of the support members in relation to one another are regulated (22), in which connection any defects of shape in the ends of the roll that is being formed can be prevented.
(FR)L'invention concerne un procédé d'enroulement d'une bande continue, dans lequel le rouleau (11) en cours de formation est soutenu dans le sens de l'axe du rouleau, au moyen d'un premier (12) et d'un second (13) organe de support placés de part et d'autre du rouleau. Dans ce procédé, on mesure la forme de l'extrémité du rouleau en cours de formation, à l'aide de mesures indirecte ou directe, et on règle les positions relatives des organes de support l'un par rapport à l'autre sur la base de ces mesures. La mesure indirecte peut consister à mesurer des forces (20) dans le sens axial du rouleau, la mesure directe pouvant consister à mesurer la ligne latérale de l'extrémité d'un rouleau, directement par mesure à contact ou par mesure sans contact. Sur la base de ces mesures, on règle (22) les positions relatives des organes de support l'un par rapport à l'autre, ce qui permet d'éviter tout défaut dans la forme des extrémités du rouleau en cours de formation.
