Abstract

PURPOSE:A drafting device in which a guide for regulating the interval of rovings is fitted near the back side of the back roller to permit the stable feed of rovings, resulting in uniform drafting. CONSTITUTION:Slivers S1 and S2 unwound from sliver bobbins are fed to back roller 1 where they are opened flatly and drafted during passing through guide pins 2 and 2, middle roller 3 and front roller 4. Then, the slivers pass through the first air nozzle 6 and the second air nozzle 7 and are wound up on a package as a spun yarn. At this time, a guide for regulating the interval of rovings is fitted near the back side of the back roller 1 to stabilize the yarn feed, whereby the fluctuation in drafting is prevented to keep the constant quality of yarns.
