2094594 9208646 PCTABS00013 A process and apparatus is described for providing a strip of flexible closure material to be affixed to a receptacle. The strip of flexible closure material comprises a combination of a plurality of interengaging strip portions in their interengaged state. The process includes the step of supplying a tape of flexible closure material having a transverse width with a plurality of interengaging elements across the transverse width that extend from the tape. Then, the tape is separated along its longitudinal length into a plurality of strip portions with at least two of the strip portions having an interengaging element extending therefrom. Lastly, the strip portions having an interengaging element are brought into contact with one another while mating the interengaging element of each of the strip portions brought together with that of the other. The process takes place continuously in line with equipment for affixing the flexible closure material to a receptacle. The separating step is accomplished by tearing the supplied flexible closure tape along its longitudinal length.
