Abstract
In the continuous manufacture of disposable diapers wherein target strips applied to the diaper are cut from a pressure-sensitive adhesive tape that has a low-adhesion backsize coating, better adhesion of adhesive closure tabs to the target strips is obtained after physically abrading the low-adhesion backsize coating. A preferred abrading medium is a low density open nonwoven fibrous abrasive web.
