Diameter monitoring system
摘要:
A method of monitoring the diameter of an elongated element (10) which is wound upon a winding unit (12).
The method comprises as steps:

(a) winding a length of an elongated element (10) having a particular diameter on a winding unit (12) with a number of angular rotations;
(b) measuring said length;
(c) measuring said number of angular rotations;
(d) using data processing means (26) that produce from said measured length and from said measured number of angular rotations a signal that is indicative of said particular diameter d.
