ABSTRACT:
Apparatus for splicing the trailing end of an old web to a new web comprises a pair of tangential fixed rollers between which the old web is fed. At each side of the fixed rollers two further rollers are supported by arms pivotted on a pin lying in the tangent plane. The old web runs over one of these rollers, while on the other the starting end of the new web is supported with a double-sided adhesive tape thereon. The roller above which the old web runs is pivotted above the other roller so that the web runs between the rollers and the webs are spliced by raising the lower roller, as the old web runs out. A cutting device separates the tail of the old web. The upper roller is then moved back to its original position for preparing a new web.
