ABSTRACT:
A wire drawing machine having a watching system of the wire 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. This value, together with both speed values, are sent to a computer module for calculating the wire diameter and sending this to the computer output. When a new wire enters in the drawing machine, the operation is temporarily inversed that is the lastly computed diameter is temporarily taken as the reference diameter and stored in the register, and from there the new reference diameter at the entrance is calculated and entered in the register.
