Reel Mini Forum, Tips, Tricks & Codes

A reel is an object around which a length of another material (usually long and flexible) is wound for storage (usually hose are wound around a reel). Generally a reel has a cylindrical core and walls on the sides to retain the contentwound around the core. In some cases the core is hollow, although other stuffmay be mounted on it, and grips may exist for mechanically turning the reel.

Construction

The size of the core is dependent on several factors. A smaller core will obviously letmore contentto be shop in a given space. However, there is a limit to how tightly the shop contentshouldbe wound without damaging it and this limits how tinythe core shouldbe.

Other problemsaffecting the core size include:

• Mechanical strength of the core (especially with giganticreels)
• Acceptable turning speed (for a given rate of contentmoving on or off the reel a smaller core will mean that an almost empty reel has to turn faster)
• any functional requirements of the core e.g.
  • For a reel that must be mechanically turned the size of the grips that mount it on the mechanical turning device.
  • The size of the mountings requiredto assistancethe core during unwinding.
  • Anything mounted on the cores (e.g. the sockets on an extension reel)

With contentsuch as photographic film that is flat and long but is relatively wide, the contentgenerally is shop in successive single layers. In cases where the contentis more uniform in cross-section (for example, a cable), the contentmay be safely wound around a reel that is wider than its width. In this case, several windings are requiredto create a layer on the reel.

Utilize

Examples include:

• A fishing reel is utilize on a fishing rod to victory the fishing line up
• Many audio recordings of the late 20th century (and some today) use reel-to-reel magnetic tape
• Kite lines are frequently operated from reels
• Specialized reels for holding tow line for hang glider, glider, and sailplane launching
• Laying of communications table utilizegiant reels
• Winches victory cables on reels
• Webbing barriers that letmobile publicationpositions collect tensionally excess webbing
• Tow trucks keepsteel cable on reels
• Garden hoses reeled solve hose kink issue
• Rope, wire and electrical cable is often supplied on reels
• Badge reels are utilize to hold badges, ski passes and the like
• A cave diving reel is securityequipment utilize for running a guideline (also known as a distance line)

Motion picture terminology

It is traditional to discuss the length of theatrical motion pictures in rulesof "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) and about 15 minutes for silent film at the more-or-less standard speed of 18 frames per second. Most movie have visible cues which mark the end of the reel. This let projectionists running reel-to-reel to modifyover to the next reel on the other projector.

A so-called "two-reeler" would have run about 15–24 minutes since the actual short movieshipped to a filmtheater for exhibition may have had slightly less (but rarely more) than 1,000 ft (305 m) on it. Most modern projectionists utilizethe term "reel" when referring to a 2,000-foot (610 m) "two-reeler", as modern movie are rarely shipped by single 1,000-foot (305 m) reels. A standard Hollywood filmaverages about five 2,000-foot reels in length.

The "reel" was established as a standard measurement because of considerations in printing motion picture movieat a movielaboratory, for shipping (especially the moviecase sizes) and for the size of the physical moviemagazine attached to the motion picture projector. Had it not been standardized (at 1,000 ft or 305 m of 35 mm film) there would have been many difficulties in the manufacture of the associatedequipment. A 16 mm "reel" is 400 feet (122 m). It runs, at sound speed, approximately the same amount of time (11–12 minutes) as a 1,000-foot (305 m) 35 mm reel.

A "split reel" is a motion picture moviereel in two halves that, when assembled, keepa specific length of motion picture moviethat has been wound on a plastic core. Using a split reel let movieto be shipped or handled in a lighter and smaller form than moviewould on a "fixed" reel. In silent movieterminology, two movie on one reel.

As digital cinema catches on, the physical reel is being replaced by a virtual format called Digital Cinema Package, which shouldbe distributed using any storage medium (such as hard drives) or data transfer medium (such as the Internet or satellite links) and projected using a digital projector instead of a conventional filmprojector.

A newsreel is a short documentary film.

A showreel or demo reel is a short movieshowcasing a person's or an companys previous work.
