In bulk applications, a paper drilling machine may be used. Then the user chooses a spine size that will match the document. Standard sizes are 4.8 mm (3 ⁄ 16 in) (for 16 sheets of 20# paper) up to 51 mm (2 in) (for 425 sheets). Spine lengths are generally 280 mm (11 in) to match the length of letter-size paper.
This holds the pin in place and the sheets of paper together. For few sheets of paper, holes can be made using the sharp end of the fastener. A split pin may be used in place of staples, but they are more commonly used in situations where rotation around the joint is desirable. This lends split pins to use in mobile paper and cardboard models ...
A binder clip (also known as a foldback clip, paper clamp, banker's clip, foldover clip, bobby clip, or clasp) is a simple device for binding sheets of paper together. It leaves the paper intact and can be removed quickly and easily, unlike the staple .
The papers are pinched between the body and the anvil, then a drive blade pushes on the crown of the staple on the end of the staple strip. The staple breaks from the end of the strip and the legs of the staple are forced through the paper. As the legs hit the grooves in the anvil they are bent to hold the pages together.
This device weighed over two and a half pounds and loaded a single 1 ⁄ 2-inch-wide (13 mm) wire staple, which it could drive through several sheets of paper. The first published use of the word "stapler" to indicate a machine for fastening papers with a thin metal wire was in an advertisement in the American Munsey's Magazine in 1901. [4]
Binding knots are knots that either constrict a single object or hold two objects snugly together. Whippings, seizings and lashings serve a similar purpose to binding knots, but contain too many wraps to be properly called a knot. [1] In binding knots, the ends of rope are either joined together or tucked under the turns of the knot.
Knot board [] on Elbe 1 (ship, 1965). A knot is an intentional complication in cordage [1] which may be practical or decorative, or both. Practical knots are classified by function, including hitches, bends, loop knots, and splices: a hitch fastens a rope to another object; a bend fastens two ends of a rope to each another; a loop knot is any knot creating a loop; and splice denotes any multi ...
A binding knot is a knot that may be used to keep an object or multiple loose objects together, using a string or a rope that passes at least once around them. There are various binding knots, divided into two types. Friction knots are held in place by the friction between the windings of line.
