Document Type and Number:
WIPO Patent Application WO/2012/008102
Kind Code:
A1
Abstract:
Disclosed is a yarn winding device which is capable of improving the degree of freedom in layout and guiding yarn to a yarn splicing device in a short time and reduces the amount of the yarn to be wasted when the yarn is spliced. The means therefor is as follows. An automatic winder is provided with a bobbin supporting unit (7), a winding unit (8), the yarn splicing device (14), a yarn guiding unit, a yarn trap (15), and a yarn trap driving unit (47). The yarn guiding unit guides, in a state wherein the yarn is divided, the yarn on a package (30) side to the yarn splicing device (14). The yarn trap (15) is located so as to face a yarn-traveling path provided between the winding unit (8) and the yarn splicing device (14) and traps, in the state wherein the yarn is divided, the yarn on a yarn-feeding bobbin (21) side. The yarn trap driving unit (47) moves the yarn trap in the direction that introduces the captured yarn into the yarn splicing device (14) while keeping the state wherein the trapped yarn straddles the yarn splicing device (14).
