Method and device for separating continuously conveyed material webs

A device for separating material webs conveyed in an essentially continuous manner in a conveyor direction, in a separating direction which is aligned essentially parallel to the conveyor direction, the device being of the type that a waste strip arises between, in each case a cutting edge of a cutting knife and a cutting edge of a counter-knife by way of two parallel cuts, said device comprising a cutting knife and a counter-knife each with a cutting edge, for creating the two parallel cuts, further comprising:

• a first and a second pair of essentially straight-lined cutting edges (3, 5 and 3′, 5′) of the cutting knife and counter-knife for creating the two parallel cuts in alternating cutting steps which are consecutive without intermediate steps or synchronous cutting steps, which are arranged cooperating in a shearing cut,
• conveying means for conveying the material webs such that they bear on the cutting edges of the counter-knives.

A separating disk comprising cutting knives that are arranged about the periphery in an alternating manner, wherein the cutting knives comprise essentially straight-lined cutting edges lying in the plane of the one or the other end-side of the separating disk, wherein each of the cutting edges comprises an end which is designed as a cutting tip and which preferably lies radially at the outside or radially at the inside.
