IN YARN PRODUCTION, APRON CLADDING MECHANISM AND METHOD TO THE ROLLERS COATED WITH ELASTIC MATERIAL AND FOUND IN THE DRAFTING AND GUDING ZONE, HAVING SHIFT STRUCTURE AND PRE-TENSIONING MECHANISM

摘要

Purposes of the invention is to reduce the roller coating elastic material of the friction impact of fiber or yarn, is used for drawing-off, and guides purpose in yarn production, therefore make operating condition and yarn property parameter. The present invention coats the especially mechanical ring compact yarn production of elastic material in yarn production to reduce grinding impact fiber in Top rollers (9), for the method for coating of backplate (17), roller (9) and above-mentioned bearing guide arm (15. are being pushed up2) it is connected to bearing body (15.1) find polar bear unit (15) on and be placed on pressure arm (3), in this way, therefore it will cover these (9,15.2) it links together, it is characterized in that; Its operating procedure stretches apron (17) and passes through tension component (22) by applying tension, continue when drawing of fiber operates, polar bear unit (15) carrying apron (17) is the horizontal plane certain intervals of displacement. Which increase during using and running be used for consideration system in, only apex roller (9) use.
