Abstract: PROBLEM TO BE SOLVED: 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. SOLUTION: 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.

Abstract: PURPOSE:To reasonably and economically produce a high temperature oven and improve the productivity of carbon fibers by arranging respective fiber blocks in plural compact stages in the high temperature oven. CONSTITUTION:A fiber belt Y comprising acrylic filaments arranged in parallel in a lateral line as organic precursors is guided into a low temperature oven in a 200-300 deg.C oxidative atmosphere and subjected to a travel in a zigzag state for a flame-resistant treatment. The fiber belt Y is divided into four fiber blocks Y1-Y4, subjected to the change of the traveling directions with the second rollers 21-24, the third rollers 31-34 and the fourth rollers 41-44, and subsequently guided into an inert atmosphere high temperature oven 1 heated to a temperature of >600 deg.C through overlapped four fiber guides vertically having distances to convert the fibers into carbon fibers, which are taken up with the fifth rollers 51-54. Grooved rollers are used as at least the second rollers 21-24 and the fourth rollers 41-44, and the inclination angle & between the inlet side and the exit side of each grooved roller is controlled so as to satisfy an inequality: theta mu100 (T is tension) for the prevention of fuzzes.
