Spiral Binding Company, started in 1932, was "the first mechanical binding company in the United States". [2] It created the original metal spiral-coil binding and later the Spiralastic, a popular plastic coil to replace wire during World War II. [ 3 ]
In the past, some comb binding machines would come with a wire closer. These machines were designed to be used with 19-loop wire, which uses the same pattern as for plastic comb binding . This hole pattern will have 19 longer rectangular holes that are on 14 mm ( 9 ⁄ 16 in) centers, for a total length of 280 mm (11 in).
Spiral coil binding uses a number of different hole patterns for binding documents. The most common hole pattern used is 4:1 pitch (4 holes per inch). However, spiral coil spines are also available for use with 3:1 pitch, 5:1 pitch and 0.400-hole patterns.
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).
