Abstract
A device for separating two webs of material which are arranged on top of each other. The webs of material are to be separated while they are being transported on a conveying device, the first of the webs of material being detachably fixed to the conveying device. The device includes a suction device which is moveable in relation to the second web of material and by which means it is able to temporarily draw the second web of material by suction and separate it from the first web of material. Two cranks are set apart, each crank rotates about a first pivot pin and is rotationally connected to the suction device by a second pivot pin. A drive device with an engaging element 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 nonparallel, and the engaging elements engage with each other in such a way that they can be displaced in relation to each other.
