Patent ID: 10538409

Abstract:
The invention discloses an apparatus for regulating winding tension as function of bobbin (2) diameter in a slit film tape or yarn (1) winder system carrying at least one automated winder. It comprises a dancing arm (3) equipped with a tension setting means or device (3B) which regulates the yarn tension. The inventive feature of the invention is that tension setting means (3B) is capable of changing resistance ‘R’ of the dancing arm (3) as a function of the bobbin (2) diameter ‘D’ during the winding process. The invention also provides a method for regulating winding tension as function of bobbin (2) diameter. The invention helps overcome a number of problems related to uniformness and consistency of package the fabric making industry is currently facing. It solves technical problem of winding bobbin throughout using same tension adjusted for dancing arm, resulting higher tension during unwinding at low bobbin sizes. It also helps reduce the necking or shrinkage of the fabric produced due to varying resultant winding tension.
