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.
摘要:
A wire drawing machine having a watching system of the wire (9) diameter at one or more watched locations in the machine. The diameter is measured by measuring the wire speed as compared to the reference wire speed at a reference location where the diameter is accurately known and held in a register (3). This value, together with both speed values, are sent to a computer module (6) for calculating the wire diameter and sending this to the output (29,30). When a new wire enters in the drawing machine, the operation is temporarily inversed : the lastly computed diameter is temporarily taken as the reference diameter and stored in the register (3), and from there the new reference diameter at the entrance is calculated and entered in the register (3).
