| description | Provided are a drawing device for a material to be drawn such as fiber by a multi-stage drawing, the device making high draw ratios possible, and a drawing method using said drawing device. Disclosed are: (1) a drawing device provided with at least one pair of tapered rollers for which the taper rate [represented by (b-a)/2L when the maximum diameter of the roller is (b), the minimum diameter is (a), and the length of the tapered section is (L)] of the tapered rollers is in the range of 0.035 - 0.50; and (2) a method for drawing a material to be drawn using said device, wherein the material to be drawn such as a yarn is extended between the pair of rollers and is drawn by extending and running the material being drawn between the tapered rollers multiple times from the small diameter end to the large diameter end.
L'invention concerne un dispositif d'étirage destiné à un matériau à étirer, tel qu'une fibre, par étirage en plusieurs étapes, le dispositif rendant possibles des rapports d'étirage élevés, et un procédé d'étirage utilisant ledit dispositif d'étirage. L'invention concerne : (1) un dispositif d'étirage pourvu d'au moins une paire de rouleaux coniques pour lesquels la conicité [représentée par (b-a)/2L lorsque le diamètre maximum du rouleau est (b), le diamètre minimum est (a) et la longueur de la section conique est (L)] des rouleaux coniques est située dans la plage allant de 0,035 à 0,50; et (2) un procédé permettant d'étirer un matériau à étirer au moyen dudit dispositif, le matériau à étirer, tel qu'un fil, étant étendu entre la paire de rouleaux et étant étiré en étendant et en faisant passer le matériau étiré entre les rouleaux coniques plusieurs fois à partir de l'extrémité de petit diamètre vers l'extrémité de grand diamètre. |
