Two-hole filebinder hole punch. Another standard also occasionally used in the US is a "filebinder" system. Its two holes are positioned symmetrically, each 2 + 3 ⁄ 4 inches (70 mm) apart from the center, i.e. 5 + 1 ⁄ 2 inches (140 mm) apart from each other. This matches the half-letter 3-hole system, except that the middle hole is omitted.
When the body is pressed to the trip point, a taper in the body forces the block sideways until the hole in the block is aligned with the hole through the hammer, and the hammer is released to strike the punch. This mechanism is used in heavy duty punches as it is less likely to bind on reset than the Sweet mechanism, it doesn't tend to wear ...
To bind a document, the user first punches holes in the paper with a specialized hole punch. Pages must be punched a few at a time with most of these machines. If hard covers are desired, they must be punched as well. In bulk applications, a paper drilling machine may be used. Then the user chooses a spine size that will match the document.
Tension along the base of the triangle forces the two sides closed, and the loops prevent the sharp steel edges from cutting into the paper. The loops also serve to hold two pieces of stiff wire, which are used as handles and allow the clip to be opened. The two slots cut in each loop are shaped so that the wire handles can be folded down once ...
A wooden clipboard. A clipboard is a thin, rigid board with a clip at the top for holding paper in place. A clipboard is typically used to support paper with one hand while writing on it with the other, especially when other writing surfaces are not available. The earliest forms were patented in 1870–1871 and referred to as board clips. [1]
A standard 8 + 1 ⁄ 2 by 11 inches (220 mm × 280 mm) sheet of paper has three holes with spacing of 4 + 1 ⁄ 4 inches (110 mm). There is a variant for half-letter size pages (8 + 1 ⁄ 2 by 5 + 1 ⁄ 2 inches or 220 mm × 140 mm), whose three rings are 2 + 3 ⁄ 4 inches (70 mm) apart. "Ledger" size binders hold 11-by-17-inch (28 by 43 cm ...
A HACO CNC punching machine Punched hole: best results for cutting surface with above 70% cutting, low clearance necessary (8% material thickness) Punch presses are developed for high flexibility and efficient processing of metal stampings. The main areas of application are for small and medium runs.
Die and punch shapes affect the force during the punching process. The punch force increases during the process as the entire thickness of the material is sheared at once. A beveled punch helps in the shearing of thicker materials by reducing the force at the beginning of the stroke. However, beveling a punch will distort the shape because of ...
