Example of a process with winders

A winding machine or winder is used for wrapping a string, twine, cord, thread, yarn,

rope, wire, ribbon, tape, etc. onto a spool, bobbin, reel, etc. The opposite process that

is getting the material off any type of core is called unwinding.

The Winder control program is used to calculate the diameter of the roll and to control

web tension and motor speed according to user given references. The diagram below

gives an overview of the winder control. The sections below explain each tension

control mode in detail with the help of control diagrams.
