ABSTRACT:
Method and apparatus for affixing index tabs to book pages include accurately embossing indicia along a continuous first strip of plastic-coated paper, adhering cardboard reinforcing strips to the first strip and slitting and scoring the resulting assembly to provide tab strip stock. The tab strip stock is severed into successive tabs and carried by vacuum-operated clamping means to an adhesive-activating station and then a tab application station. Successive pages of a book are fed past the tab application location; those to be provided with tabs are stopped at various positions relative to the tab application locations and the clamping means folds tabs around the edges of selected pages.
