Title:
SPINNING MACHINE, YARN WINDING SYSTEM, AND METHOD FOR MANUFACTURING YARN SUPPLY BOBBIN
Document Type and Number:
WIPO Patent Application WO/2016/194509
Kind Code:
A1
Abstract:
A spinning machine (3) is provided with: a state acquisition unit (310) for acquiring material depletion, which is a state in which coarse yarn (13) from a coarse yarn bobbin (10) whereon coarse yarn (13) is wound has run out; a plurality of roller pairs (331, 332, 333) having, respectively, bottom rollers (331a, 332a, 333a) and top rollers (331b, 332b, 333b) for drafting the coarse yarn; a plurality of drive units (331c, 332c, 333c) for driving the bottom rollers of each of the plurality of roller pairs; and a drive control unit (312) for controlling at least one of the plurality of drive units such that when the state acquisition unit has acquired the material depletion, the coarse yarn after drafting is fatter than that prior to the acquisition of material depletion.
