The present invention features a web feeding and transition system for exchanging a first, used, web roll for a second, fresh, web roll, so that web material is conveyed along a web-conveying feed path. Each web of the first and second web rolls includes a backing or a separate, interleaved web. The web assembly has a first work station having a mounting for allowing the first web roll to unwind and feed the first web to the feed path. A second work station has a mounting adjacent the first mounting for allowing the second web roll to unwind so that the second web may be spliced to the first web. A "bump splicing" vacuum roll disposed upon the first work station causes an adhesive section of the fresh web to contact an end portion of the exhausting web, as the web roll runs out.
