In offshore applications, huge lengths of rope are often housed on drums. The anchor winches on Saipem's Semac 1 pipe laying barge, for example, each hold 2,800 metres of 76mm (3 inch) diameter wire rope in 14 layers. Saipem's Castorone, the world's largest pipe laying vessel uses a wire rope that is 3,850m long and 152mm in diameter. It weighs ...
[1] [2] [3] Some reels or skein winders are made without the gear mechanism (see swift (textiles)). They perform the same function, but without the "clock" or pop to aid the spinner in keeping track of the length of thread or yarn produced. A niddy noddy is an even simpler version.
Retractable cable reels are particularly useful for environments where access to electricity or air is needed in a wide variety of places. All retractable hose reels operate using a constant-force spring to provide torsion for the spool, and a ratcheting mechanism to prevent the cable from retracting while it is being used.

A reel is a tool used to store elongated and flexible objects (e.g. yarns/cords, ribbons, cables, hoses, etc.) by wrapping the material around a cylindrical core known as a spool. Many reels also have flanges (known as the rims ) around the ends of the spool to help retain the wrapped material and prevent unwanted slippage off the ends.
Yarn is spun on a great wheel with the long-draw spinning technique, which requires only one active hand most of the time, thus freeing a hand to turn the wheel. The great wheel is usually used to spin short-staple fibres (this includes both cotton and wool), and can only be used with fibre preparations that are suited to long-draw spinning. [23]

Spool (software company), a software company that allows users to save video and text onto their mobile devices to view the content offline; Spool pin, a type of pin used in pin tumbler locks to prevent picking; Simultaneous Peripheral Operation On-Line, Spooling, a form of multi-programming for the purpose of copying data between different devices
The term "spool" may originate with the Simultaneous Peripheral Operations On-Line [2] [3] (SPOOL) software; [4] this derivation is uncertain, however. Simultaneous peripheral operations on-line may be a backronym. [5] [verification needed] Another explanation is that it refers to "spools" or reels of magnetic tape, although “spool” is an ...
