Abstract
An index system for indexing directories such as telephone books includes a paper guide strip positioned adjacent a film plastic tab strip segmented into a plurality of uniquely identified tabs spaced along the tab strip. The guide and tab strips are coupled to one another along adjacent edges by means of an adhesive transfer strip extending the length of the guide and tab strips along the junction thereof on one side. As tabs are removed for application, the pressure-sensitive adhesive is transferred to the tabs while the guide and transfer strips serve as a guide for positioning the tabs on the pages of the directory.
Claims7
An index tab assembly comprising:
- a tab strip, initially free of adhesive, defining a plurality of tabs;
- an adhesive transfer strip comprising a base strip made of a material from which adhesive is readily removeable and an adhesive film initially adhered to said base strip, said adhesive transfer strip being adhered to and extending from said tab strip spaced from an edge thereof for transferring a pressure-sensitive adhesive from said adhesive transfer strip to a portion of each tab of said tab strip as the tabs are removed from said adhesive transfer strip.
An index tab assembly comprising:
- a tab strip, initially free of adhesive, defining a plurality of tabs with indicia printed directly on a surface of said tabs;
- an adhesive transfer strip comprising a base strip made of a material from which adhesive is readily removeable and an adhesive film initially adhered to said base strip, said adhesive transfer strip being adhered to a surface of said tab strip and extending along said tab strip spaced from an edge thereof for transferring a pressure-sensitive adhesive from said adhesive transfer strip to a portion of each tab of said tab strip as tabs are removed from said adhesive transfer strip;
- said adhesive transfer strip being sufficiently wide that it overhangs said tab strip;
- and
- guide means adhered to said overhanging portion of said adhesive transfer strip by the adhesive thereon for permitting alignment of said tab strip with respect to a page of a directory.
