Reel

A coil or roll is an element made ​​of cardboard, wood, plastic or steel, is wound on the material with round cross-section such as yarn, rope, wire, cable or ribbon-like material, such as magnetic tape, film, and paper. Coil as both the core alone or the core, including the material wound therearound is referred to.

See also Kops (textile).

In contrast to a reel, which also serves the winding of different materials, is a coil not a standalone device or no technical aids, but only a replaceable component of a device (eg spinning wheel or camera) or a disposable item, the only transport, distribution and utilization is.

The following forms can be distinguished:

  • Disc coil ( cylindrical and projecting limits on the end faces )
  • Cylindrical coil or roll
  • Conical coil.

  • 2.2 plumbing

Coil (textile)

Coils - even sleeves - in accordance with DIN 61805 are used for winding yarns and can be made of hard paper, cardboard, wood, plastic or aluminum, the coil with the coiled material is also referred to as coil and regulated in DIN 61800. They are either Tubular or still possess additional side windows on both sides ( disc coils ). No side windows are required at intersecting winding the yarn, these so-called cross-wound bobbins are specified in DIN 61801.

Spinning

Spinnradspulen are always flat coils, mostly made ​​of wood. In so-called industrial Spinnerein cylindrical bobbins are used as yarn tubes, on which the spun yarn is wound.

Weave

Weaving yarns are usually presented in the guise of cylindrical or conical cross coils are wound on a core of rigid cardboard or plastic. The cylindrical shapes to 250g are used mainly in hand-weaving, large cones of 1-2 kg weight in industrial weaving. In the house weaving also reusable warp bobbins were used as pancake coil made ​​of wood, was rewound to the other carriers ( cross coil or strands ). For self- shot wound coils thin cylindrical yarn tubes of cardboard are used.

Sewing thread is marketed both as a cylindrical ( for industrial use also conical) cheese as a pancake. In sewing machines disk coils are used in steel or plastic for the bobbin thread.

Embroider

The reel is the caseless, spool -wound thread reservoir in a Stickschiffchen.

Other applications

Photo and sound

  • Reels of tape to tape recorders and tapes
  • Film rolls for film cameras and projectors, in particular plug coils and special design
  • Rolls of film for cameras

Sanitary area

  • Simple roles usually made ​​of cardboard, for example, for toilet or kitchen paper

Electrical Engineering

  • Industrially used cable drums or reels ( also called Tourets ) of hand-sized ( eg plastic drums for wire ) to drums with several meters in diameter, which must be transported on flatbed trucks own. The latter are used especially in the laying of cables used.
  • Cable drum or cable reels ( in Switzerland and Austria called " cable reel " )

Cable reels in common language, understanding it is actually cable winder according to DIN VDE 620 part 300 or DIN VDE 623 Part 100 The data used as extension cable for electrical connections in the private or craft area cable scooters (also reel called ) a hand crank for winding is applied in addition and incorporated into the drum, one or more outlets.

Note that the maximum power, which may have attached devices together in a coiled drum is lower than that of the unwound cable, since it is difficult for a coiled pipe to a unaufgerollten heat dissipation. This allows much easier accumulation of heat, overheat, burn and cable fire occur. Therefore, cable drums should always be completely unrolled before use.

Modern cable drums are usually equipped with an overtemperature fuse that interrupts the flow of current in case of overheating. However, the presence of such assurance and their proper function are not always readily apparent. If the overtemperature protection has tripped immediately pull all the plugs, both of the cable drum and the connected devices. Furthermore, the line should be completely unrolled so that the cable can cool. It should also be that the over-temperature protection automatically resets at some cable drums after cooling, whereby current flow is possible. Since all devices connected can then start up again, which can be very dangerous for devices with electrically moving parts ( eg drill, circular saw ), it is very important to pull the plug. Higher-quality cable reels are equipped with over-temperature protection, the manual must be after tripping and cooling touch of a button reset.

On higher-quality cable drums are information, may be connected to what maximum total output devices with completely or partially rolled and unrolled completely cable drum.
