Rhone-poulenc Viscosuisse Sa

The apparatus for draining dyed yarn on yarn bobbins includes a vacuum pump; a hollow dye carrier insert for carrying a plurality of yarn bobbins having yarn to be drained thereon, an interior volume of this dye carrier insert being connectable to the vacuum pump and structured so that, when at least a partial vacuum is produced in the interior volume by the vacuum pump, air is drawn through the yarn on the bobbins into the interior volume; a vacuum tank connected to the vacuum pump for producing a vacuum as ballast and having a capacity not less than the interior volume of the dye carrier insert; a coupling device for receiving the dye carrier insert on which the yarn bobbins are mounted; a bell releasably mountable on the coupling device to enclose the dye carrier insert carrying the yarn bobbins in a vacuum-tight manner and a connecting pipe with a valve connecting the coupling device to the vacuum tank and operable so as to be able to form the partial vacuum in the dye carrier insert for draining the yarn carried on the yarn bobbins. No centrifuge for the yarn spools and no rotation devices for the dye carrier insert and the yarn bobbins are necessary to remove water from and drain the yarn resulting in a more economically operated apparatus.
