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.
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 ...
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]
Two basic systems were developed to drive the tape across the recording head: spool drive and capstan-drive. [11] [12] Most tape recorders move the tape by pinching and pulling it between a motorized capstan, a rotating metal shaft or spindle, and a larger rubber idler roller, called a pinch wheel or pinch roller. This ensures tape speed ...
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 ...
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.
