Description

A single-hole punch makes a single hole per activation, usually at an arbitrary position (i.e., without alignment guides).

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 binder's inventor, Andreas Tengwall, supposedly named it after a consortium consisting of himself and two companions, i.e. a trio. [ citation needed] The binder can be opened at any place while holding the papers in place, as the inner holes have guide pins from one side, the outer holes have pins from the other side.Generally holes are punched in the binding gutter. Depending on the binding technology, it might be difficult to read what’s printed near the holes, even through bending the sheet. That’s why it is recommended to punch the holes in the margin, wide enough to account for the binding and its inconveniences", which should really be a no-printing zone. Consequently, the best setting is to enlarge the inner margin (which allows for duplex printing with correctly balanced uneven margins). This size of hole punch is regarded as the gold standard of hole punches. It punches two holes at a time, which are a distance of 80mm apart, which is the equivalent of 8cm, or 3.15 inches. The holes should be 12mm or half an inch from the edge of the paper. The hole is usually punched at a diameter of 6±0.5 mm depending on the manufacturer. A hole punch, also known as hole puncher, or paper puncher, is an office tool that is used to create holes in sheets of paper, often for the purpose of collecting the sheets in a binder or folder (such collected sheets are called loose leaves). A hole punch can also refer to similar tools for other materials, such as leather, cloth, or plastic or metal sheets.

Specialized hand-operated tape punches were used to perform small edits and repairs on punched paper tapes used for data entry into teletypes or early computers. Torn or damaged tapes were sometimes aligned with specialized jigs, spliced with special adhesive tape, and the holes encoding data were manually restored using such punches. 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. This size of hole punch is set by the International Organization for Standardization and is therefore accepted as the standard size of hole punch across the world. When using this hole punch on paper, those papers will be compatible to be bound by a two-ring holder. 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. In Sweden, a four-hole national standard [7] is almost exclusively used. The centers of the holes are 21mm, 70mm and 21mm apart, 10.5 ±0.5mm from the edge of the paper. The guides help keep the paper in a straight line. Konica-Minolta specifies that the holes should be 11 ±1mm from the edge of the paper [6] for European 4-hole arrangements, contrary to ISO838.
