description Un cylindre râcleur perfectionné particulièrement indiqué pour être utilisé dans un appareil photo instantané présente une texture formée de protubérances en forme de pointe. Un profil complexe est conféré au cylindre en faisant varier la hauteur des protubérances le long de la surface du cylindre. Dans un procédé et un appareil permettant de fabriquer le cylindre, on utilise un faisceau de laser impulsionnel pour produire les protubérances, et on fait varier l'énergie de chaque impulsion en fonction d'un programme prédéterminé pour régler la hauteur d'une protubérance formée. An improved squeegee roller particularly suited for use in an instant camera has a texture formed by stud-like bumps. A complex contour is provided to the roller by varying the heights of the bumps along the roller surface. In a method and apparatus for producing the roller a pulsed laser beam is used to produce the bumps and the energy of each pulse is varied according to a predetermined program to adjust the height of a bump formed.
