Abstract
A rotatable yarn cooling drum for cooling yarn plugs emanating from two texturizers has a circumferential perforated shell about which the yarn plugs are wound and cooled. A deflector in the form of a finger is spaced radially from the surface of the shell and laterally positioned between the ends of the shell. A yarn guide radially spaced from the drum has two yarn guide grooves for guiding the yarn plugs onto the shell at one side of the deflector and one lateral end of the shell. The yarn plugs may thus enter onto the shell at one lateral end and exit at the other lateral end after making more than a complete turn on the drum. The guide slots are illustrated as formed in a block to which the finger is attached.
Claims14
A rotatable yarn cooling drum for cooling yarn plugs emanating from at least two texturizers, said drum including a hollow annular cylindrical shell having a surface with perforations communicating with the hollow so that ambient air may be drawn through the perforations into the hollow when a sub-atmospheric pressure is applied to the hollow, said shell comprising a finite length formed between a pair of spaced apart lateral ends, a deflector having two sides spaced radially from the surface of said shell and disposed intermediate said lateral ends to define first and second segments of said shell, said first segment of said shell being located on one side of said deflector and said second segment of said shell being located on the other side of said deflector, and a yarn guide having an inlet and an exit for guiding a yarn plug from each of said texturizers onto said first segment of the surface of said shell at said exit of said guide, said deflector being located adjacent said exit, whereby said yarn plugs enter onto said first segment and are wound onto said second segment and exit from said shell after making more than one complete turn about said shell.
A rotatable yarn cooling drum for cooling yarn plugs emanating from at least two texturizers, said drum including a hollow annular cylindrical shell having a surface with perforations communicating with the hollow so that ambient air may be drawn through the perforations into the hollow when a sub-atmospheric pressure is applied to the hollow, said shell comprising a finite length formed between a pair of spaced apart lateral ends, a deflector comprising a finger having an arcuate configuration conforming substantially to the configuration of the surface of said shell, and said deflector spaced radially from the surface of said shell and disposed intermediate said lateral ends to define first and second segments of said shell, and a yarn guide having an inlet and an exit for guiding a yarn plug from each of said texturizers onto said first segment of the surface of said shell at said exit of said guide, said deflector being located adjacent said exit, whereby said yarn plugs enter onto said first segment and are wound onto said second segment and exit from said shell after making more than one complete turn about said shell.
