Abstract:
A method for threading a material web through a processing plant, in which the material web is divided by a longitudinal cut into a first narrow part and a second broad part, the first part being passed through the processing plant while the second part is separated, the width of the first part is increased successively so that a growing share of the material web is passed through the processing plant, so that finally the the entire width of the material web is passed through the processing plant, and the material web is pulled through the processing plant by a controllable force,wherein the successive increase of the width of that part which is passed through the processing plant is preceded by an initial interval with an essentially constant width, wherein the successive increase of the width of that part which is passed through the processing plant occurs through at least two monotonously growing phases with an intermediate interval with an essentially constant width, and wherein the magnitude of the controllable force is automatically adjusted to the width of the first part of the material web.
