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.
Industry | Winder Name | Roll Name |
Paper, Textile, Film | Winder | Roll |
Wire | Takeup, Reeler | Reel |
Wire | Spooler | Spool |
Metal | Coiler | Coil |
Textile | Beamer | Beam |
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.
