Title (EN) METHOD AND DEVICE FOR MEASURING THE DIAMETER OF A ROLL OF WEB MATERIAL
(FR) PROCEDE ET DISPOSITIF PERMETTANT DE MESURER LE DIAMETRE D'UN ROULEAU DE MATERIAU EN BANDE CONTINUE
Abstract: front page image
(EN)The method for measuring the diameter of a reel or roll of wound web material (N) involves the following steps: rotating said reel (L); detecting at least twice the moment when a given point (Lf) on the web material (N) passes a predetermined position; determining the time that elapses between said two passes or the amount of rotation ($g(a)) of the supporting roller (5); and calculating the diameter (D) of the reel (L) from said time (T) and the peripheral speed (V) of the reel (L) of from said amount of rotation ($g(a)) and the radius (R) of the supporting roller (5).
(FR)Le procédé de mesure du diamètre d'une bobine ou d'un rouleau de matériau en bande continue enroulé (N) consiste à: faire tourner ladite bobine (L), détecter au moins deux fois le moment où un point donné (Lf) de la bande (N) arrive sur un emplacement prédéfini, déterminer le temps écoulé entre lesdits passages ou le nombre de rotations ($g(a)) du rouleau support (5) et calculer le diamètre (D) de la bobine (L) à partir dudit temps (T) et de la vitesse circonférentielle (V) de la bobine (L) ou bien à partir dudit nombre de rotations ($g(a)) et du rayon (R) du rouleau support (5).
