Abstract

Copy sheets issuing from a copier or like reproduction apparatus are stuck together into sets of two to 50 sheets. As the sheets enter the finisher seriatim, each is registered on a collation shelf. After that, an area of adhesive material is applied near a corner of the exposed sheet, preferably by an adhesive "patch" being transferred from a carrier strip to the sheet. Depending on whether the adhesive is hot-melt or pressure activated, after the next sheet has been registered, its corner is pressed down by a hammer (which may be heated) to glue the two corners together before an adhesive patch is applied to the now top sheet, and the cycle repeated.
