Abstract
Abstract A laterally adjustable web splicing device for accommodating webs of varying width. The web splicing device comprises a stationary plate for supporting one edge of a pair of web ends to be spliced together, and a movable plate laterally movable relative to the stationary plate for supporting the opposite edge of the web ends. The movable plate is movable between a first position, in which it abuts the stationary plate and cooperates therewith to support web ends of one width, and second position, in which the movable plate is spaced from the stationary plate for supporting a web end of a wider width. In the second position, a web supporting insert plate is interposed between the stationary and movable plates.
