The present invention features a web feeding and transition assembly for exchanging a first, used, web roll for a second, fresh, web roll, so that web material will be continuously 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 transition assembly has a first mounting for allowing the first web roll to unwind and feed the first web to the feed path. A second mounting adjacent the first mounting allows the second web roll to unwind so that the second web may be spliced to the first web. A "bump splicing" unit causes an adhesive section of the second web to contact an end portion of the first web, as the first web roll runs out. Thus, a continuous web feed is accomplished by splicing the first and second webs "on the fly"; the new, incoming roll is caused to match the speed of the expiring roll within one revolution.
