EXTRUSION LINE FOR COATING EXTENDED METAL PART

摘要

PURPOSE: To provide an extrusion line constituted of a replacing apparatus having two extrusion heads and capable of mutually moving the respective heads between an operation position and a preparation position. CONSTITUTION: An extrusion head 12 is mounted on the support 11 supported by a movable assembly 8 and moved from a preparation position to an operation position by rotating two arms 9, 10 around the revolving shaft on a base 6. Other one extrusion head 14 present at the operation position is removed before this by the opening of a clamp 21 after the operation of other one movable assembly 18 to be capable of reaching the preparation position. Then, a new production equipment is arranged and adjusted at a proper place and controlled to preheat the extrusion head.
