To prevent the generation of malfunction while quantitatively inspecting the condition of a yarn package and accurately performing the feed back of a result to a manufacturing requirement by providing a means for unraveling the yarn from a yarn package and a sensor for detecting the dynamic position of the unraveled yarn.
In an inspecting device, a yarn package 1 is wound on a bobbin 2, and installed in a wind-out shaft 3 so as to be supported. A motor 4 is connected to a wind-out shaft 3, and the number of revolution is controlled. The yarn 5 is unraveled from the package 1 in the radial direction of the package 1 through a touch roll 6. Unraveling is performed by the suction by a suction gun 7, and the unraveled yarn 5 is sucked by the suction gun 7 through a traverse fulcrum guide 8 fixed to a constant position. A sensor 10 for detecting the dynamic position of the unraveled yarn 5 is provided on the way of the passage of reeling thread 9 from the touch roll 6 to the traverse fulcrum guide 8. Furthermore, signal can be transmitted between a data processing personal computer.
