Zusammenfassung:	Apparatus (4400) for splicing expiring (4404) and replenishing (4405) webs of a web material includes first and second spaced platens (4401, 4402) having respective facing inner surfaces defining a passageway for transit of the expiring web, where the platens (4401, 4402) are adapted for displacement toward and away from one another in a reciprocating manner. The first platen (4401) is adapted to engage an end of the replenishing web (4405), while the second platen (4402) is adapted to engage and position the moving expiring web (4404). Moving the platens (4401, 4402) together with their respective inner surfaces in close proximity to one another causes a cutting die on the first platen to sever the expiring web (4404) forming outfeeding and infeeding ends of the expiring web, and to attach the expiring web's outfeeding end to the replenishing web (4405). Attached to the second platen (4402) in facing relation to the first platen (4401) and engaging the expiring web (4404) is an ironing pad (4408) to ensure firm contact and adhesion of expiring web (4404) to the replenishing web (4405). During web splicing, the cutting die is transferred from the first (4401) platen to the second platen (4402) to free the replenishing web (4405) from the first platen (44019, with the cutting die engaging and collecting or holding the expiring web's infeeding end.
