Abstract

L'invention concerne un appareil rotatif à grande vitesse pour la perforation de bandes flexibles. L'appareil comprend une série de poinçons 112 effectuant des mouvements alternatifs dans un anneau porte-poinçons 110, ainsi qu'un anneau portant une série de matrices correspondantes. Le mouvement alternatif des poinçons dans et hors des matrices est produit par un anneau extérieur excentré. La bande 300 à perforer défile dans une zone entre les poinçons et les matrices et est guidée à l'entrée et à la sortie de l'appareil par un dispositif 250 qui dévie la bande et la tourne en même temps autour de son propre axe. L'invention est applicable en particulier à la perforation de pellicules cinématographiques et de bandes magnétiques.The invention relates to a high speed rotary apparatus for perforating flexible webs. The apparatus comprises a series of punches 112 performing reciprocating movements in a punch carrier ring 110, as well as a ring carrying a series of corresponding dies. The reciprocating movement of the punches in and out of the dies is produced by an eccentric outer ring. The strip 300 to be perforated passes through an area between the punches and the dies and is guided at the entrance and at the exit of the apparatus by a device 250 which deflects the strip and at the same time turns it around its own axis. The invention is particularly applicable to the perforation of cinematographic films and magnetic tapes.
