ABSTRACT:
A multi-ply pad, such as a disposable diaper, is cut from a series of interconnected pads by a combined severing and sealing tool having a knife blade which severs through the multi-ply links on which the pads are serially interconnected. The knife edge is immediately followed by a blunt heel which seals the multiple plies of sheet material together. Accordingly, when the separated pads are sequentially handled to be folded, the multiple plies at one end of the pad will not flare or otherwise become disoriented with respect to each other and to the pad. This greatly facilitates and simplifies handling of the pads after they are severed.
