Coil winding and unwinding machines are used for winding webs, paper or wire into coils or unwinding webs, paper or wire from coils. A coil winding machine is used to wound wire on a coil by rotating the coil winder at a speed of several hundred turns per minute. There are many types of coil winding and unwinding machines. Examples include a single spinder coil winder, fully automatic coil winder, an oscillating coil unwinder, and single station unwinders. A coil unwinding machine uses a coil unwinder to unwind coils. Other coil winding and unwinding machines are commonly available.
There are several ways in which coil winding and unwinding machines function. Coil winding and unwinding machines can maintain desired tension during winding and unwinding processes and can also display tension on line during continuous winding operation. Some specifications of a coil winding machine includes the type of coil that can be used, wire gauges, winding speed, layer height, layer length, pitch setting, winding tension, and weight of coil. A coil winding machine can be used for layer winding for items such as solenoids and bobbins. A dereeler or tensioning system in a coil winder increases the speed of coil winding and can improve wire layering on the coils. The Dereeling and decoiling applications are governed by the laws of inertia. Factors affecting inertia include max weight, max speed, and accel/decel time. The three basic methods for unwinding coils most commonly used are coil cradles, centering reels, and pallet decoilers. A coil cradle holds a coil by its outside diameter cradling it on powered rollers called nest rolls. A centering reeler holds the coil by its inside diameter over a mandrel with an expanding arbor assembly. Pallet decoilers or pan reelers load an entire pallet of pancake or oscillated wound coil and are used primarily in narrow strip applications. Coil winding and unwinding machines can be designed and manufactured to meet most industry specifications.

Coil winding and unwinding machines are used in many applications. Some examples include making solenoid bobbins, transformer coils, choke coils, inductor coils, and generator coils. Coil winding and unwinding machines should adhere to electromagnetic interference (EMI) standards.
