ABSTRACT:
Apparatus for splicing the end of a terminating reel to the outer layer of a subsequent reel: a splicing tube is either swingable or reciprocable to move between a waiting position out of contact with the strip to be cut and an operating position where the splicing tube moves transversely to and into contact with the strip and moves the strip to a position where it can be cut by a knife. A knife movable between a waiting position where it will not cut the strip and a cutting position where movement of the splicing tube to the operating position moves the strip to contact the knife for cutting. The knife is supported to be moved between its positions either by swinging or by movement along a guide path. The splicing tube includes a vacuum zone which holds the strip to it, and the splicing tube is rotatable on its axis for maintaining the tension of the strip.
