Method and device for changing strip material on a production machine.

摘要

A method and device whereby a first runout strip (3), fed at a first speed (V1) along a guide (12) by a traction device (13), is replaced with a new strip (33) by: cutting the first strip (3); activating both a push device (9,49), by which the new strip (33) is engaged and fed along the guide (12) at a second speed (V2), and a movable guide device (17) defining a portion of the guide (12) and which is lowered in relation to the rest of the guide (12) and together with a trailing portion (92) of the first strip on the movable guide device (17) itself; controlling the second speed (V2) as a function of the first speed (V1) so that a leading portion (91) of the new strip (33) is superimposed on the trailing portion (92) of the first strip (3) along the movable guide device (17).
