    Abstract: PURPOSE:To obtain the titled device which reduces temperature nonuniformity in a muffle and tar mist occurring at local low-temperature part, improves physical properties and qualities of carbon yarn and stabilizes calcination process, wherein a preheated atmosphere gas is fed to a furnace. CONSTITUTION:A preheated atmosphere gas is fed to a high-temperature calcining furnace to treat yarn continuously. The temperature of the atmosphere gas fed is preferably set in such a way that the ratio of the temperature ( deg.K) of the atmosphere gas fed/the temperature of ( deg.K) atmosphere in muffle is 0.6-1.

    Abstract: PURPOSE:To obtain the titled apparatus having long service life of the furnace center tube material because of making it possible to prevent consumption of the furnace center tube material and capable of providing a carbon fiber having improved quality, by constituting the apparatus so as to cool a sealing liquid in liquid seal part provided at the opening part for taking out a fiber filament in lower part of the furnace. CONSTITUTION:A liquid seal part 3 is provided at the opening for taking out a fiber filament in the lower part of a furnace in a heat-treating apparatus for continuously treating the fiber filament and the apparatus is constituted so as to cool a sealing liquid 4 in said liquid seal part. Water, cooled at

    Abstract: PURPOSE:The roaster is provided with a two-dimensional sealing mechanism on its opening to prevent the yarn from trembling with the gas flow coming in whereby the yarn is not damaged. CONSTITUTION:The sealing mechanism 10 at the opening 2a of the roaster 2 for preoxidation or carbonization is composed of cell material 3 and cell part 4. The cell material 3 is constituted from sectioning parts 11a and 11b so that a plurality of cells 12 which have been formed with the parts 11a and 11b open in the substantially same direction, then change continuously in the different direction from the yarn-running direction. The cell part 4 is a panel 13 blocking the cell material 3 on one side. The sealing mechanism has a gap epsilonwhich has a space enough to pass the yarn without contact and is formed with a couple of the cell materials 3 blocked with the cell part 4 on their backs. Additionally, the cell materials are provided with yarn guides 16, 16 whose gaps are narrower than the gap between the cell materials 3 on the top and bottom.

    Abstract: PURPOSE:To prevent the generation of turbulence in a coagulation liquid, thereby preventing the disturbance and entanglement of spun yarns in a wet spinning to collect multiple yarns in the form of a fan and taking up the collected yarns, by placing a specific circulation partition plate between the spun yarn and the bottom of the coagulation bath. CONSTITUTION:A circulation partition plate 8 is placed between the spun yarn Y and the bottom surface 4 of a coagulation bath 1 having a fan shape when viewed from the top. The lower sides of the plural spun yarns Y are separated completely from the bottom surface 4 by the plate 8. the distance between the partition plate 8 and the spun yarn are maintained at a definite level throughout the whole length of the plate. The upstream-side of the spinneret 5 is the starting end and the upstream-side of the over-flow port 3 is the finishing end of the spinning. The gap between the partition plate 8 and the bottom surface 4 is made larger toward the over-flow port 3.

    Abstract: PURPOSE:An inspection device capable of examining nozzle holes of spinneret having a spherical surface-shaped spinneret plate, equipped with a specific support stand, a supporting column, a shaking arm and a spinneret placing stand having a rotary means. CONSTITUTION:A support stand 3 capable of traveling in parallel with a plane a perpendicularly intersecting to an incidence axis 2 of a magnifying lens 1 is equipped with a support column 4. An arm 5 which perpendicularly intersects to the plane of the support stand 3 and can shake in parallel with a plane simultaneously moving with the support stand 3 is axially born on the support column 4. A spinneret placing stand 6 is attached to the tip of the shaking arm 5. The stand 6 is provided with a rotary means 7 and when a lug 7a thereof is rotated, a spinneret 8 is made ratatable around the central axis thereof through gears 7b and 7c, a bearing 7d, a thrust bearing 7e, etc.
