Abstract:
1. A method of manufacturing folder sheets with reinforced holes, comprising the steps of: (a) causing a paper band to go through corona treatment to condition the surface of the band to receive hot-melted thermoplastic material; (b) applying a reinforcement strip of hot-melted thermoplastic material to selected areas of the paper band to form a partially reinforced paper band; (c) cutting the partially reinforced paper band in a predetermined direction to form a plurality of paper strips each having an elongated-reinforced edge area including the reinforcement strip of thermoplastic material; (d) layering and counting the paper strips until they reach a predetermined number; (e) punching holes in the paper strips in the reinforced edge area; (f) cutting the punched paper strips in a direction substantially perpendicular to the predetermined direction to form a plurality of folder sheets; and (g) packaging the folder sheets.
