ABSTRACT:
A method of changing a first out-running strip with a new strip on a manufacturing machine having a traction device for feeding the first strip to the machine at a first predetermined speed, and a strip guide located upstream from the traction device; which method provides for stages consisting in cutting the first strip; activating a push device upon the trailing end of the first strip passing through a given point along the strip guide, the push device being engaged by the new strip for feeding the same along the strip guide at a second predetermined speed; controlling the second speed as a function of the first speed, so that the leading portion of the new strip overlaps a corresponding trailing portion of the first strip along the strip guide; and de-activating the push device subsequent to engagement of the new strip by the traction device.
