Abstract
Method and apparatus for applying adhesive attaching tapes to pads, such as diapers, in which an elongated strip of adhesive tape having an adhesive face and a non-adhesive back is folded longitudinally about a hinge line to form tape wings having their non-adhesive backs together and their adhesive faces facing away from each other. A release liner is applied to the adhesive face of one of the wings, leaving the adhesive face of the other wing exposed. Discrete folded tape segments are severed from the folded strip and are transferred from the vicinity of the severing tool to the vicinity of the pad by drawing the lined wings of the folded tape segments by vacuum against a vacuum drum. The adhesive face of the exposed wing faces outwardly of the drum. The drum is rotated to adhere the adhesive face of the exposed wing to a portion of the pad in the course of drum rotation. The lined wing is then free to have the liner stripped therefrom and unfolded about the hinge line for application of the exposed wing to another portion of the pad.
