Abstract
Abstract A flat or tubular textile web is transported in a loose random condition through a tunnel by stream of a chemical treating fluid, such as a cleaning fluid, by which the web is treated and cleaned before being transported by an elastic conveyor to a second tunnel in which the web is transported in the loose random condition by streams of drying air. Drive means dip the tunnel into a bath of the treating liquid in a container.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
185 words
Apparatus for continuously treating a long textile material, comprising, in combination, substantially horizontal tunnel means having an inlet and an outlet at the ends thereof and openings between said ends; nozzle means for discharging a chemical treating liquid under pressure into the region of said inlet so that a stream of pressure liquid flows through said tunnel means for transporting a long textile material introduced into said inlet in loose random condition through said tunnel means and out of said outlet; an open container located under said tunnel means and being filled with said treating liquid to a predetermined level, said container having a transverse width only slightly exceeding the transverse width of said tunnel means; and cyclically operating drive means connected with said tunnel means for moving said tunnel means in an up-and-down movement through said level so that said tunnel means is alternately located in and above said treating liquid, Said tunnel means entering said treating liquid, forcing treating liquid located laterally of said tunnel means in said container through said openings into said tunnel means and into contact with the textile material.
Claim 2
Dependent Claim
185 words
Apparatus for continuously treating a long textile material, comprising, in combination, substantially horizontal tunnel means having an inlet and an outlet at the ends thereof and openings between said ends; nozzle means for discharging a chemical treating liquid under pressure into the region of said inlet so that a stream of pressure liquid flows through said tunnel means for transporting a long textile material introduced into said inlet in loose random condition through said tunnel means and out of said outlet; an open container located under said tunnel means and being filled with said treating liquid to a predetermined level, said container having a transverse width only slightly exceeding the transverse width of said tunnel means; and cyclically operating drive means connected with said tunnel means for moving said tunnel means in an up-and-down movement through said level so that said tunnel means is alternately located in and above said treating liquid, Said tunnel means entering said treating liquid, forcing treating liquid located laterally of said tunnel means in said container through said openings into said tunnel means and into contact with the textile material.
Claim 3
Dependent Claim
48 words
Apparatus as claimed in claim 1 wherein said drive means include means for moving said tunnel means in a movement having, in addition to the up-and-down movement, a component in the longitudinal direction of said tunnel means so that said tunnel means moves also longitudinally in said container.
Claim 4
Dependent Claim
81 words
Apparatus as claimed in claim 2 wherein said drive means include at least one crank arm having a lower end pivotally connected with said tunnel means; and a rotary driven means to which the upper end of said crank arm is pivotally connected, said rotary driven means having a horizontal axis of rotation transverse to said tunnel means so that said tunnel means swings with said crank arm in longitudinal direction while being raised and lowered by said rotary driven means.
Claim 5
Dependent Claim
84 words
Apparatus as claimed in claim 2 comprising a second tunnel; blower means for blowing air into one end of said second tunnel; and means for transporting said textile material from said outlet of said tunnel means to said one end of said second tunnel so that said textile material is transported in a loose random condition into said second tunnel and transported through the same by the air flowing through said second tunnel in said loose random condition while said textile material is dried.
Claim 6
Dependent Claim
161 words
Apparatus for continuously chemically treating a long textile material, comprising, in combination, tunnel means having an inlet and an outlet; and a nozzle for discharging a chemical treating fluid under pressure into the region of said inlet so that a stream of pressure fluid flows through said tunnel means whereby a long textile material introduced into said inlet is transported in loose random condition through said tunnel means and out of said outlet of the same while being continuously treated by said treating fluid; a second tunnel; blower means for blowing air into one end of said second tunnel; and means for transporting said textile material from said outlet of said tunnel means to said one end of said second tunnel so that said textile material is transported in a loose random condition into said second tunnel and transported through the same by the air flowing through said second tunnel, in said loose random condition, while said textile material is dried.
Claim 7
Dependent Claim
161 words
Apparatus for continuously chemically treating a long textile material, comprising, in combination, tunnel means having an inlet and an outlet; and a nozzle for discharging a chemical treating fluid under pressure into the region of said inlet so that a stream of pressure fluid flows through said tunnel means whereby a long textile material introduced into said inlet is transported in loose random condition through said tunnel means and out of said outlet of the same while being continuously treated by said treating fluid; a second tunnel; blower means for blowing air into one end of said second tunnel; and means for transporting said textile material from said outlet of said tunnel means to said one end of said second tunnel so that said textile material is transported in a loose random condition into said second tunnel and transported through the same by the air flowing through said second tunnel, in said loose random condition, while said textile material is dried.
Claim 8
Dependent Claim
88 words
Apparatus as claimed in claim 5 comprising an open container located under said tunnel means and being filled with said chemical treating fluid, said fluid being a liquid; and cyclically operating drive means for moving said tunnel means into and out of said container; and wherein said tunnel means has openings so that the liquid in said container enters said tunnel means through said openings whereby successive portions of said material are immersed in the treating liquid in said container when said tunnel means enters said container repeatedly.
Claim 9
Dependent Claim
41 words
Apparatus as claimed in claim 6 wherein said container has dimensions only slightly exceeding the dimensions of said tunnel means so that the liquid in said container is forced through said openings into said tunnel when the same enters said container.
Claim 10
Dependent Claim
54 words
Apparatus as claimed in claim 5 comprising a casing in which said tunnel means, said transporting means, said second tunnel, and said container are located, and having an inlet gate and an outlet gate through which said textile material enters and leaves, said inlet and outlet gates retaining the treating fluid in said casing.
Claim 11
Dependent Claim
49 words
Apparatus as claimed in claim 5 comprising return conduit means having a portion surrounding said second tunnel; and wherein said second tunnel has openings at least in the end portion remote from said one end so that air passes through said openings into said return conduit means for recirculation.
Claim 12
Dependent Claim
57 words
Apparatus as claimed in claim 5 wherein said means for transporting include a convEyor having transporting rollers and two endless conveyor belts passing over said transporting rollers and forming a gap for said textile material between said outlet and said one end of said second tunnel and for transporting said textile material in said loose random condition.
Claim 13
Dependent Claim
37 words
Apparatus as claimed in claim 10 wherein said conveyor belts are elastic; and wherein said transporting rollers have at least peripheral parts thereof made of an elastic material for maintaining said textile material in said random condition.
Claim 14
Dependent Claim
15 words
Apparatus as claimed in claim 10 comprising resilient means for yieldingly supporting said transporting rollers.
Claim 15
Dependent Claim
40 words
Apparatus as claimed in claim 5 wherein said tunnel means and nozzle form a first unit; wherein said transporting means with said conveyor form a second unit; and wherein said second tunnel and said blower means form a third unit.
