Claims
- 1. In an arrangement for treating a textile web having a pile in which the web is required to enter and leave a treatment station with its pile facing upward, an apparatus for positioning the pile threads of a textile web fabricated from heat sensitive, synthetic material, which is comprised of:
- a. means in the form of a substantially vertical tank having a top and a bottom and spaced sides extending substantially vertically betwen said top and bottom for storing a heated liquid of predetermined temperature, said means having an inlet and outlet opening in one of said spaced sides near the top of said means;
- b. means to guide the textile web into said means for storing and from said means for storing through said opening such that the textile web enters said means for storing below the point at which the textile web exits said means for storing, for storing said means filled with said heated liquid to a level closely adjacent the point where the textile web enters said means for storing;
- c. a passageway of width at least equal to the width of the textile web under said means for storing;
- d. means for routing said textile web through said passageway beneath said means for storing from the one of said sides opposite said opening and upward to said opening and into said heated liquid;
- e. means for guiding said textile web through said heating liquid, first vertically downward and then vertically upward, for a predetermined period of time, said guide means contacting only the back side of said web, and said web being contacted by no other structure while within said heated liquid;
- f. means disposed approximately at the top of said heated liquid and within said means for storing for changing the direction of said web from vertical to substantially horizontal thereby bringing said web to a substantially horizontal position immediately after removal from said heated liquid; and
- g. means for maintaining said web after removal from said heated liquid substantially horizontal for a second period of time, said means for maintaining in cooperation with said means for changing also directing said web out of said means for storing through said opening in said means for storing.
- 2. The apparatus of claim 1 further comprising means for forced cooling said web after removal from said for storing means.
- 3. The apparatus of claim 2 wherein said means for forced cooling includes means for recovering a substantial portion of the heated liquid which is retained by said web.
- 4. The apparatus of claim 3 further comprising means for returning the recovered heated liquid to said means for storing.
- 5. The apparatus of claim 3 and further comprising additional means, positioned within said means for storing, adjacent said pile, immediately after the point where said web has been directed from a vertical to a substantially horizontal position for recovering a portion of the heated liquid retained by said web prior to said recovery of heated liquid by said means for forced cooling.
- 6. The apparatus of claim 5 further comprising means, for returning the recovered heated liquid to said means for storing.
- 7. The apparatus of claim 6 further comprising means for agitating said heated web before said web is routed into said liquid.
- 8. The apparatus of claim 2 wherein said means for forced cooling is comprised of a suction device positioned vertically above said web, said suction device spanning the width of said web.
- 9. The apparatus of claim 1 further comprising means for agitating said web before said web is routed into said heated liquid.
