Abstract (en)

[origin: EP2657382A2] A yarn monitoring device (6) includes a holder (30), a detecting section, and a blowing section (45). The holder (30) is provided with a first yarn passage (34) for enabling passage of a spun yarn travelling along a predetermined yarn path. The detecting section is adapted to detect at least at a portion of a side wall surface (35) of the first yarn passage (34), status of the spun yarn. The blowing section (45) is adapted to blow compressed air in a predetermined blowing direction to the side wall surface (35) of the first yarn passage (34), and configured such that when viewed in a direction orthogonal to the yarn path and parallel to the side wall surface (35), the blowing direction is set diagonal to the side wall surface (35).
