Title
(EN) METHOD FOR ALIGNING CYLINDERS HAVING PARALLEL AXES
(FR) PROCEDE D'ALIGNEMENT DE CYLINDRES A AXES PARALLELES
Abstract
(EN)
A method for aligning cylinders having parallel axes, wherein the angular deviation between the axis of at least one cylinder and a reference direction is determined, and the position of the cylinder is adjusted to reduce the deviation. The direction of the axis of a first cylinder, considered as the reference direction, is determined, and the reference direction is moved to a position that is at least adjacent to a second cylinder. The direction of the axis of the second cylinder is determined and the angular deviation between the direction of the axis of the second cylinder and the reference direction is deduced therefrom. Said reference direction is moved by means of a gyroscope, preferably a triaxial optical gyroscope.

Procédé d'alignement de cylindres à axes parallèles, dans lequel on détermine l'écart angulaire entre l'axe d'au moins un cylindre et une direction de référence et on règle la position de ce cylindre pour réduire l'écart déterminé. On relève la direction de l'axe d'un premier cylindre, considérée comme direction de référence, et on transporte cette direction de référence au moins jusqu'à proximité d'un deuxième cylindre; on détermine l'orientation de l'axe de ce deuxième cylindre et on en déduit l'écart angulaire existant entre la direction de l'axe de deuxième cylindre et la direction de référence. On transporte cette direction de référence au moyen d'un gyroscope, de préférence un gyroscope optique à trois axes.
