The invention relates to a device for separating two lines of material which are arranged on top of each other. The lines of material are to be separated whilst they are being transported on a conveying device, the first of the lines of material being detachably fixed to the conveying device. The inventive device comprises a suction device (8, 9), which is moveable in relation to the second line of material and by which means it is able to temporarily draw the second material by suction and separate it from the first line of material. The device also has two cranks (10, 13) which are set apart and which each rotate about a first pivot pin (10a, 13a) and are each rotationally connected to the suction device (8) by a second pivot pin (10b,13b). The inventive device is characterised by a drive device with a peripheral engaging element which is connected to an engaging element configured on one of the cranks. The paths of revolution of the drive device engaging element and the crank engaging element do not coincide and are non- parallel and the engaging elements engage with each other in such a way that they can be displaced in relation to each other.
L'invention concerne un dispositif qui permet de séparer deux bandes de matériau superposées durant leur déplacement sur un dispositif transporteur, la première bande étant posée amovible sur ledit transporteur. Le dispositif comprend un système d'aspiration (8, 9), mobile par rapport à la seconde bande de matériau, qui aspire par intermittence ladite seconde bande et la sépare de la première; et deux vilebrequins (10, 13) disposés à distance l'un de l'autre. Chaque vilebrequin tourne autour d'un premier axe de rotation (10a, 13a) et est relié rotatif au dispositif d'aspiration (8) par un second axe de rotation (10b, 13b). Le dispositif de l'invention est caractérisé par un dispositif d'entraînement comprenant un élément de préhension rotatif, relié à un élément de préhension formé sur l'un des vilebrequins. L'élément de préhension du dispositif d'entraînement et l'élément de préhension du vilebrequin tournent en décrivant des trajets qui ne coïncident pas et ne sont pas parallèles, et ils s'engrènent avec un décalage.
