The invention concerns a method of regulation in winding, wherein a number of separate rolls (13a, 13b) are formed around separate roll cores placed one after the other side by side while supported by support members (11, 12) and while loaded by linear loads produced by the truncated rolls (14a, 14b) in a set of truncated press rolls (14). In the method of regulation, the distance at each particular time between at least one truncated roll (14a, 14b) in the set of truncated press rolls (14) and the beam (16) that loads the set of truncated press rolls (14) is measured. The measurement signal (S) is passed to a regulator (23), which gives a regulation signal (d) to the valves that control the actuators (17) of the beam (16) so as to adjust the distance between the beam (16) and the set of truncated press rolls (14) to the desired measure.
L'invention concerne un procédé permettant de réguler un bobinage. On forme un certain nombre de rouleaux distincts (13a, 13b) autour de mandrins successifs adjacents, qui sont supportés par des éléments supports (11, 12) et chargés par des charges linéaires produites par les rouleaux tronqués (14a, 14b) faisant partie d'une série de rouleaux de presse tronqués (14). Selon le procédé de régulation, on mesure la distance à chaque instant entre au moins un rouleau tronqué (14a, 14b) de la série de rouleaux de presse tronqués (14) et la potence (16) qui charge la série de rouleaux (14). Le signal de mesure (S) est transmis à un régulateur (23), qui envoie un signal de régulation (d) aux soupapes commandées par l'actionneur (17) de la potence (16), de façon à régler sur la mesure désirée la distance entre la potence (16) et la série de rouleaux (14).
