METHOD FOR MANUFACTURING TAPE TAB STOCK THAT MAY BE USED TO PRODUCE TAPE TAB FASTENERS FOR DISPOSABLE ABSORBENT ARTICLES

摘要

A method for manufacturing tape tab stock that may be used to produce tape tabs (40) for use with disposable absorbent articles, as well as a method for manufacturing tape tab stock that can be produced on-line and concurrently with the disposable absorbent article to which the tape tabs (40) are joined. The first step in the process is to provide a backing substrate (52) upon which the adhesives of the tape tab can be applied. Once the backing is provided, a pressure sensitive adhesive (54) is applied to regions of one side of the backing substrate. The backing substrate (52) is then slit in a direction parallel to the machine direction and the release surface of a release substrate is placed in contact with the pressure sensitive adhesive (54), forming a laminate comprising the backing substrate (52) and the release substrate. The release substrate preferably covers the entire surface of the backing substrate (52) upon which pressure sensitive adhesive (54) has been applied. The surface of the laminate, including the surface of the release substrate that is not in contact with the pressure sensitive adhesive (54), and any of the backing substrate (52) not covered by the release substrate is then coated with a second adhesive for joining the tape tabs to the absorbent article. After the second adhesive is applied to the surface of the laminate, the laminate is slit in a direction parallel to the machine direction and either rewound for shipping or storage, or fed to a taper unit that is integrated into the absorbent article manufacturing line. The taper unit cuts individual tape tabs (40) and applies them to the absorbent article chassis.
