<P>PROBLEM TO BE SOLVED: To evenly cool yarn which is spun from a spin beam. <P>SOLUTION: A yarn cooling device comprises a cooling air supply box 22 in which a cooling-cylinder housing chamber 41, an upper side connection channel 42, a lower side connection channel 43 and others are formed. The cooling-cylinder housing chamber 41 stores a plurality of cooling cylinders 21 such that they face a plurality of spinnerets 13 of a spin beam 2. The plurality of cooling cylinders 21 are arranged zigzag in two lines in a left to right direction. Also, the cooling-cylinder housing chamber 41 is provided with a first connection port 45 and a second connection port 46 at lower end parts of side wall surfaces 41a and 41b, respectively. To the first connection port 45, the upper side connection channel 42, which is connected to a duct 60 and elongated in a left to right direction, is connected. To the second connection port 46, the lower side connection channel 43, which is disposed below the upper connection channel 42, connected to the duct 60, and elongated such that it passes around below the cooling-cylinder housing chamber 41, is connected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
