Core yarn manufacturing apparatus

摘要

Conventional core manufacturing apparatuses are classified into two types according to the types of core fibers. One of the two types manufactures a CSY (Core Spandex Yarn) using an elastic yarn as corefibers. The other type manufactures a CFY (Core Filament Yarn) using a filamentyarn as core fibers. Both types are exclusive to each other and thus have poor general purpose properties. The present invention provides a core yarn manufacturing apparatus including a draft device (100) that drafts sheath fibers (9) of a core yarn and a core fiber supply device (1) that supplies core fibers of the core yarn, wherein the core fiber supply device (1) is configured so that a feed-out path of the core fibers in the core fiber supply device (1) is inclined above the draft device (100) 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 (2) and a CFY yarn guide (12) are provided in a rear upper part of a base frame (10) of the core fiber supply device (1), the wind-out device (2) supporting a CSY package (3) and winding out an elastic yarn (4), the yarn guide (12) guiding a filament yarn (14) drawn out from a CFY package (13) located behind the core fiber supply device.
