ABSTRACT:
For accurate correlation of the punch pins and edge guide for a paper punch or the like, a gage sheet of predetermined length is formed with accurately located holes corresponding to the desired location of the holes or slots to be punched in paper of similar length (e.g., end holes equidistant from top and bottom of the sheets). Such gage sheet may be pre-punched and of a permanent character, or may be prepared by trial and error by adjusting the edge guide until the end holes are equidistant from the edges of the sheet. The punch pins are lined up with the gage holes and then the edge guide is moved snugly against the edge of the gage. The gage is then removed. The edge guide is mounted on a transversely movable slide visible through a window in the platen on which the paper is to rest. Markings for different paper lengths may be permanently displayed on the platen at an edge of the window. Markings on the platen may be affixed by applying thereto a decal having paper length markings thereon. Accurate positioning of the edge guide after factory assembly is thus possible. In the preferred embodiment, a mark is placed on the slide in line with the marking on the platen corresponding to the particular length of the gage. Preferrably, such mark on the slide is affixed to a decal which is placed on the slide in the proper location.
