Adjustable Variable Frequency Controller Drives for Winding in Textile
Winding is a procedure to take up and package material in roll form, for more efficient handling or in preparation for a subsequent operation. In a typical industrial application, a winder is employed to roll up a continuous or limited length of material such as wire, paper, film, metal, or textiles. The winder and finished roll are referred to by different names in different industries.

Wound materials may be stretchable or non-stretchable. Winding of stretchable materials is more complex and critical than non-stretchable materials.
Materials typically wound include:
|
· Wire Cable
|
· Foils
|
· Textile Materials
|
|
· Paper
|
· Metals
|
· Glass Fiber Materials
|
|
· Business Forms
|
· Textile
|
· Plastic Film
|
Generally, plastic film is extensible (stretchable) material, most other materials can be considered non-extensible. Rolls may be wound by applying drive torque at its center or its surface. As a result the two major categories of winders are:
· Center Winders
· Surface Winders
Winder drives are designed to improve the wound package and eliminate material breakage.

Tips:
A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
