Apparatus for automatically applying reinforcing tabs to loose-leaf sheets |
摘要 |
A method and apparatus for automatically applying reinforcing tabs to sheets in a loose-leaf binder includes a projecting tab guide sized to fit within a ring of the loose-leaf binder and adapted to apply a reinforcing tab between the edge of the sheet and a hole in the sheet through which the ring passes. Pressure-sensitive adhesive-back reinforcing tabs are separated from the carrier strip as the strip passes around a deflecting edge adjacent to an end of the tab guide. An inclined pressure foot presses the separated tab onto the sheet to attach it thereto.
