Abstract
Methods of changing from manufacture of pant-type refastenable personal care articles of a first size to manufacture of such pant-type refastenable personal care articles of a second different size. A method of the invention comprises defining in the workpiece, at at least one side edge of the respective workpiece, a length of material defined in the machine direction, wherein activity, or inactivity, of such length of material, in combination with other elements of the workpiece, determines the size of the pant-type refastenable personal care article being so produced, whereby the length of material so defined can be activated and thereby incorporated into the personal care article to correspondingly produce a relatively larger size such personal care article, or inactivated and thereby excluded from the personal care article to correspondingly produce a relatively smaller size personal care article.
