Abstract (en)

[origin: EP2868609A1] There is provided a yarn supplying system capable of maintaining the tensile force of the yarn in a yarn supply path in an appropriate range, and supplying the yarn from the bobbin without slackening of the yarn with a simple configuration. The yarn supplying system includes a yarn storing device (2) and a control means (1C). The yarn storing device (2) includes a storing unit (10) that stores a yarn (3Y) reeled out from a bobbin (3) in the middle of a yarn supply path, a pull-in piece (20), a filament (30), an elastic body (40), and a displacement detector (50). The pull-in piece (20) pulls in the yarn (3Y) toward the storing unit (10) and linearly reciprocates along a pull-in direction. The filament (30) is connected to the pull-in piece (20) and includes a turn back portion (30t) at the middle, and reciprocates by interlocking with the reciprocate movement of the pull-in piece (20) without substantially stretching or contracting. The elastic body (40) is connected to the filament (30). The displacement detector (50) detects displacement of the filament (30) from an origin position. The control means (1C) controls a supply amount of the yarn (3Y) from the bobbin (3) based on the displacement of the filament (30) from the origin position.
