    Abstract: PURPOSE:To reduce an amount of a treating medium leaked from the interior of a treating device, by fixing a detachable closing member to a slit opening for yarn feed of the yarn treating device. CONSTITUTION:In a yarn treating device which has a protruded section, is equipped with a treating chamber 2 in the interior, has a protruded part 4 provided with a slit opening 5 for yarn feed, communicated with the treating chamber 2 and has end plates 10 at both the ends of the treating chamber 2, equipped with a slit opening 11 for yarn feed, a door 13 covering the protruded part 4 is provided with a rubber packing 16 to close the slit opening 5 of the protruded part. Further, the treating device is detachably provided with a closing member 35 to close the slit opening 11 of the end plates 10 at both the ends of the treating chamber 2.

    Abstract: PURPOSE:To efficiently remove a liquid attached to a yarn, by providing a constricted member of a special structure in a yarn outlet of a liquid bath for introducing a melt extruded yarn, cooling and solidifying the yarn. CONSTITUTION:A constricted member 4 having a gas inflow port 25, a gas discharge port 30 and a gas passage 28, communicating with both and crossing a yarn passage is provided in a yarn outlet of a cooling liquid bath 2. A sleeve 19 having a slender slit 20 of about the same thickness as that of a yarn is preferably provided between a gas inflow port 26 and the gas passage 28.

    Abstract: PURPOSE:To attain a control without variation in the tension of a film regardless of presence of eccentricity of a winding core by employing a suction device for sucking the film in the direction to give slack to the film. CONSTITUTION:When the tension of a film 1 decreases, the film 1 between guide roll 2 and 3 slacks due to suction force of a suction device 7, and a position detection device 15 detects the slack to make a control device 14 work to increase the drive force of a core drive device 12. As a result, the rotation of a shaft core 9 is accelerated, the winding up tension of a roll-like film 10, namely the tension of the film 1, increases. When the tension of the film 1 increases on the contrary, the slack of the film 1 between the guide rolls 2 and 3 decreases, the position detection device 15 detects the decrease in the slack to make the control device 14 work to decrease the drive force of the winding core drive device 12. As a result, rotation of the shaft core 9 is decelerated and the winding tension of the roll-like film 10, namely the tension of the film 1, decreases.
