Rolling mill for copper wire

Abstract

Disclosed is a rolling mill for copper wire. The rolling width of the mill roller can be automatically and accurately regulated by using the signal from the thickness measurement sensor, so that a copper wire with precise size can be obtained all the time. In addition, the copper wire can be kept tension by means of a plurality of tension regulation device, and then can be winded equably by the precise measure of the thickness of the copper wire.

Description

technical field [0001] The present invention relates to a rolling mill for copper wire, and more particularly to a rolling mill in which the rolling width of the mill rolls is automatically fine-tuned based on detected signals so that the copper wire is always rolled into Precisely sized and the rolled copper wire is held under tension by multiple tension adjustments to accurately measure the thickness of the wire and wind the wire onto a collection spool. Background technique [0002] Generally, flexible flat cables are used in various electronic products. Such a flexible cable has a structure in which a plurality of copper wires are installed inside and a resin material is coated on the outside. Also, the copper wire used in the flexible flat cable is made to a predetermined size using conventional rolls. [0003] Meanwhile, a copper wire roll and a rolling method thereof are disclosed in Korean Patent Publication No. 379185 filed by the applicant of the present inventio...
