Abstract
Web-shaped packaging material, which is to be cut into strips for integration into a package, is fed through a web-changing device which has knives and two conveying sections, the conveying sections converging upstream of the strip-cutting station. In order to be able to perform a web change-over, the web-changing device comprises a fixed knife arranged between the two conveying sections and movable knives which cooperate with the fixed knife for severing the respective webs of packaging material to produce leading and trailing edges which correspond to the shape of the front and rear edge of the strips. A deflecting device for the severed front end of a new web of packaging material is provided in each conveying section.
