ABSTRACT:
A method of manufacturing folder sheets with reinforce holes, which comprises unwinding a spindled paper band; printing predetermined graphics on the paper band; causing the paper band to go through corona treatment; applying a reinforcement strip of thermoplastic material to selected areas of the paper band; cutting the printed and partially reinforced paper band in a direction substantially perpendicular to one edge of the paper band in such a fashion as to form a plurality of paper strips each having an elongated reinforced edge area; layering and counting the paper strips until they reach a predetermined number; punching the paper strips in the reinforced edge area in accordance with a predetermined pattern; cutting the punched paper strips in a direction substantially perpendicular to the direction of the first cutting to form a plurality of folder sheets; counting and piling the folder sheets to form a block until they reach a predetermined number; and packaging and boxing the folder sheet blocks.
