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.
3 + 3 ⁄ 4 in/s and 7 + 1 ⁄ 2 in/s are the speeds that were used for (the vast majority of) consumer market releases of commercial recordings on reel-to-reel tape. 3 + 3 ⁄ 4 in/s is also the speed used in 8-track cartridges. 1 + 7 ⁄ 8 in/s is also the speed used in Compact cassettes.
35mm film reels and boxes 16mm empty film reel with its metal container It is traditional to discuss the length of theatrical motion pictures in terms of "reels". The standard length of a 35 mm film reel is 1,000 feet (305 m), which runs approximately 11 minutes for sound film (24 frames per second ) [ 2 ] and about 15 minutes for silent film ...
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 ...
[1] [2] Guide lines are also useful in the event of silt out. [3] A cave diver running a distance line into the overhead environment to facilitate a safe exit. Distance lines are wound on to a spool or a reel for storage, and are laid in situ by unrolling. [4] The length of the distance line used is dependent on the plan for the dive.
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.

Film is commonly checked for broken sprocket holes before presentation, a process known as "spooling". Mechanical devices exist for this purpose, but the classic method is to place the finger and thumb of a gloved hand on the edges of the film, which is mounted on a winding bench, and to slowly run the film through the fingers, feeling for snags.
