Each of the bottom rollers 12 through 14 of a drafting device 11 is divided into two line shafts 12a through 14a and 12b through 14b and driven by driving motors 15a and 15b from the ends of the machine base. Each line shaft consists of a plurality of roller shafts 21 connected to each other through threaded engagement of screw portions 21a and 21b formed at the ends thereof. Proximity switches 23a and 23b are provided at positions corresponding to those roller shafts 21 of the line shafts 14a and 14b of the back bottom roller 14 which are situated at the driving side ends, and proximity switches 22a and 22b are provided at positions corresponding to those roller shafts 21 situated at the ends on the side opposite to the driving side. <IMAGE>
