The notion of reel has several uses. The term comes from cart , a concept that can refer to an element that moves horizontally and that allows something to be held.
A cylinder that has edges on the bases and usually has a hole in its axis is called a reel. These items are used to coil or twist cables , threads , ribbons or other similar products, allowing them to be kept coiled.
Sewing machines , for example, use spools of thread . These spools are placed in the corresponding sector and the person can operate the mechanism of the sewing machine. However, those who sew by hand also use spools to store threads and make the task easier.
fishing reels
In fishing rods , the reel is the piece that allows you to wind the fishing line (the thread that is tied on one side to the hook and on the other to the rod rope). Its most important function is to collect and store the thread on a spool .
The reel itself is integrated with other devices and structures, such as the crank and brake . There are electric reels , fixed spool reels and many other models, whose characteristics make them more or less appropriate for a certain type of fishing .

The photographic rolls
In the field of photography , film reels were very important. The notion refers to the cylinder that allows a film to be rolled (a generally celluloid tape that can be photographically impressed) or to the film roll itself.
The rolls always used to be made of celluloid, although later they began to use different plastics. Its surface is coated with a photographic emulsion that includes silver bromide or another substance that is sensitive to light .
When the emulsion on the reel receives light, the image is faintly printed on the film. Then, through the developing process , said image is stabilized and enlarged.
These photographic reels lost relevance with the development of digital photography . While film photography uses a chemical procedure, digital photography uses sensors to convert light into electrical signals that are digitized and stored in a memory .
