Abstract:
1. A web-spreading process, comprising the steps: a) conveying a first web strand and a said second web strand next to one another in a web-processing machine and offset in parallel to one another by a spread; b) wrapping the first web around a first deflecting means, which forms a first deflection axis, and a second deflecting means, which is a next deflecting means downstream along the web and forms a second deflection axis, each of the first deflecting means and the second deflecting means having a wrapping angle and providing a first web parallel offset; c) adjusting at least one of the first deflecting means and second deflecting means from a first position into a new, second position, in which the first web strand travels between the first deflecting means and the second deflecting means over a path length that is different from that in the first position, but maintaining a conveying direction so that the spread is adjusted, but said wrapping angle is not changed by the adjustment of said at least one of the first deflecting means and second deflecting means.
