ABSTRACT:
A core yarn manufacturing apparatus includes a draft device that drafts sheath fibers of a core yarn and a core fiber supply device that supplies core fibers of the core yarn, wherein a feed-out path of the core fibers in the core fiber supply device is inclined above the draft device in such a manner that a front of the feed-out path is lower than a rear of the feed-out path with respect to a front surface of a machine frame, and wherein a CSY wind-out device and a CFY yarn guide are provided in a rear upper part of a base frame of the core fiber supply device, the wind-out device supporting a CSY package and winding out an elastic yarn, the yarn guide guiding a filament yarn drawn out from a CFY package located behind the core fiber supply device.
