APPARATUS FOR APPLYING STEAM TO A TOW An apparatus for applying steam to a tow of filaments wherein a housing having an opening for the passage of the tow therethrough is provided with a plurality of steam conduits positioned in the housing and extending across the path of the tow. Each conduit is provided with a slit for directing steam through the tow at an angle of 30.degree. to 75.degree. to the path of the tow, with the slits in the conduits being so positioned that steam from some of the conduits flows countercurrent to the tow and steam from the other conduits flows concurrent with the tow. Preferably, the conduits are mounted in pairs with the tow passing therebetween and with the slit in one conduit of each pair being positioned to direct steam in a direction countercurrent to the direction of tow movement and the slit in the other conduit of the pair being positioned to direct steam in a direction concurrent to the direction of tow movement. |
