Rapesco PF25A001 Single Hole Punch Model 25, 10 Sheet Capacity, Silver

Product Information

Punching one page at a time and leaving half the circle still attached is time consuming and not productive. Hole punches for larger volumes of paper (hundreds of sheets) feature longer lever arms, but function similarly.

The travel distance of the cylinder is generally very short -- the thickness of the paper sheets -- so the cylinder can be positioned close to the lever fulcrum. The official name of this four-hole system is triohålning, since it was adapted to the "Trio binder" which was awarded Swedish patent in 1890.The two additional holes provide more stability in 4-ring binders, while still allowing 4-hole paper to fit 2-ring binders. The binder's inventor, Andreas Tengwall, supposedly named it after a consortium consisting of himself and two companions, i.

A hole punch does not necessarily make round or square holes in a sheet of paper; instead, it may create certain shapes along the edge of the sheet. Friedrich Soennecken filed his patent on 14 November 1886, for his Papierlocher für Sammelmappen, a multiple-hole punch and office supply product.

This is a single-hole punch which also crimps a metal fastening loop around the hole, similar to a rivet.The first record for a single-hole puncher—a ticket punch—was published in 1885, when Benjamin Smith helped create a spring-loaded hole puncher that had a receptacle to collect the chads.

Holding up to 80mm of papers, these clips are ideal for binding hole-punched documents with two holes, or square cut folders. This allows the chads to be pushed up and out the top, as the paper is being cut, making it more suitable for thicker volumes of paper. A later paper punch was refined in 1893 by Charles Brooks, and it was referred to as a ticket punch due to its early role in punching train tickets as trains became increasingly popular and common between 1850 and 1900. Two holes are punched in accordance with the standard, plus two additional holes located 80mm to the outside of the standard holes. Single-hole punches are widely used in the British Civil Service where papers are punched with a single hole in the upper left, and secured using a treasury tag.This extension is sometimes referred to as the "888" system, because of the three 8-cm gaps between the holes. The ASCII character code included a special DELETE or DEL character defined as all holes punched out (code 7F), allowing an erroneous character to be canceled by punching extra holes.
