ABSTRACT:
A device for punching a plurality of holes adjacent the edge of one or more sheet members comprises a pair of elongated jaw members pivotally joined intermediate their lengths in scissors-like fashion. A punch is carried on one end of one jaw member and an aligner is positioned in side by side relation to the punch in fixed spaced relationship therefrom. A punch die is carried by the other jaw member to receive the punch. The aligner and the punch each extend downwardly from the upper jaw member and terminate in lower ends, the lower end of the aligner protruding downwardly a predetermined distance below the lower end of the punch. The jaw members are pivotable from an open position wherein the punch and aligner are spaced from the die to a closed position wherein the punch is matingly received within the die and the aligner is positioned beside the die.
The method of the present invention comprises placing the sheet member in covering relation over the die, punching a punch downwardly through the sheet member and into the die so as to create a punched hole of predetermined configuration, removing the punch upwardly from the sheet member, realigning the sheet member below the punch by sliding the paper laterally and aligning the first punched hole below the aligner, moving the aligner downwardly into the first punched hole whereby the aligner positions and holds the paper against lateral movement, and punching the punch downwardly to form a second punched hole in a predetermined position with respect to the first punched hole.
