ABSTRACT:
An apparatus and process are described herein for positioning the pile threads found on textile webs manufactured from synthetic fibers which become pliable upon exposure to heat. Means are provided for first routing the textile web through heating means which generally would be a hot water bath. The pile threads are softened by the heat of the hot water bath and become sufficiently pliable as to enable them to assume any position. Because of their buoyancy in water the pile threads tend to orientate themselves perpendicular to the web backing. In order to maintain the pile threads perpendicular until given a chance to cool, the web is removed from the heating apparatus in substantially a horizontal plane. Suction means are provided to cool the textile web as it leaves the heating portion of the apparatus thereby speeding up the set time of the piles. The suction means can also be used to remove a substantial portion of the hot water saturating the textile web. The water can be returned to the hot water bath for reuse.
