Abstract (en)

A yarn winding machine comprising: a yarn supplying section (9) adapted to supply a yarn (10); a yarn pooling device (22) adapted to pool the yarn (10) supplied by the yarn supplying section (9); and a winding section (26) adapted to wind the yarn (10) from the yarn pooling device (22) to form a package (50) and includes a rotation driving unit (54) adapted to rotate the package (50), wherein the winding section (26) is adapted to cause the rotation driving unit (54) to stop rotation of the package (50) before the yarn (10) is disconnected or after the yarn (10) is disconnected but before a yarn end is wound onto the package (50), further comprising: a second yarn monitoring device (70) arranged between the yarn supplying section (9) and the yarn pooling device (22) and adapted to monitor a state of the yarn (10); a second yarn cutting device (9) adapted to cut the yarn (10) upstream of the yarn pooling device (22) when the second yarn monitoring device (70) detects a yarn defect; a yarn joining device (23) adapted to join the yarn (10a) from the yarn supplying section (9) and the yarn (10b) from the winding section (26); and a catching and guiding device (28) adapted to catch the yarn (10b) from the winding section (26) and to guide the yarn (10b) to the yarn joining device(23), wherein the winding section (26) is adapted to stop the rotation of the package (50) such that a yarn end formed by the cutting of the yarn (10) by the second yarn cutting device (9) is positioned at a predetermined position on a yarn traveling path.
