Reel Histories
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 (known as a '' spool'') with flanges around the ends (known as the ''rims'') to retain the material wound around the core. In most cases the core is hollow in order to pass an axle and allow the reel to rotate like a wheel, and crank or handles may exist for manually turning the reel, while others are operated by (typically electric) motors. Construction The size of the core is dependent on several factors. A smaller core will obviously allow more material to be stored in a given space. However, there is a limit to how tightly the stored material can be wound without damaging it and this limits how small the core can be. Other issues affecting the core size include: * Mechanical strength of the core (especially with big reels) * Acceptable turning speed (for a given rate of material ...
