Description

July 12, 1966 G. SCHIFFER 3,260,000 PRESSURE ABSORBER ARRANGEMENT FOR PROCESSING WEBS OF TEXTILE GOODS Filed July 9, 1962 Imam/r04 Giint rer Schiffer y ,2 w 7 o United States Patent 4 Claims. 61. 34-442 The present invention relates to a pressure absorber. Pressure absorbers with continuous passage of goods therethrough are known, according to which a wide web of textile material is subjected to a steam pressure which is higher by several atmospheres than ordinary atmospheric pressure. With these heretofore known pressure absorbers, the goods are passed into -a pressure absorber in form of a pressure container through the intervention of a sealing device which, in most instances, consists of a sealing roller system, said goods passing between two sealing rollers. One of the sealing rollers has to be designed as an elastic roller in order to make sure that a good seal It has been found that the sealing ability decreases with higher steam pressures. While this drawback can at least to some extent 'be overcome by applying a higher squeezing pressure between the sealing rollers, the rollers will in such an instance be operated at high squeezing pressure also when a lower inner pressure prevails, with the result that the sealing strips are subjected to an unnecessarily high stress, and also the drive for the roller system is subjected to unnecessary stresses while the impregnated textile material is squeezed unduly.
It is therefore an object of the present invention to provide a pressure absorber which will overcome the above-mentioned drawbacks.
It is another object of this invention to provide a pressure absorber of the general type set forth above, which will have a relatively long life, is simple in construction, and highly effective.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawing in which:
FIG. 1 shows partly in view and partly in section a pressure absorber arrangement according to the present invention;
FIG. 2 is a plan view of a portion of the arrangement of FIG. 1, with parts broken away.
The present invention is characterized primarily in that the pressing device for producing the squeezing pressure is, through a pressure conduit, communicating with the inner pressure of the pressure absorber whereby in addition to a preselected basic pressure, automatically an additional pressure is eifected which at all times corresponds to the respective inner pressure.
According to a further feature of the invention, also the pressure to which the sealing strips between the sealing rollers and the pressure container are subjected, is controlled through a pressure conduit in conformity with the inner pressure of the pressure absorber.
Referring now to the drawings in detail, the arrangement shown therein comprises a sealing device in the form of two steel rollers 1 having pressed thereagainst an elastic roller 2, which is located above said steel rollers 1. The elastic roller 2 is pressed against the steel rollers 1 by a pressing device 11 which may be of any standard construction. The sealing of the steel rollers 1 with regard to the pressure container 5 of the pressure absorber is effected by two sealing strips 4 which are equipped with elastic or metallic sealing lips. The said sealing rollers and sealing strips are journalled in a rectangular body 3. It is at the end faces 3a of said supporting said rollers. Fitting pieces 3b are adjustable to compensate for wear at the end faces of rollers 1. The goods 7 to be introduced into the pressure absorber pass between a steel roller 1 and the elastic roller 2 into the The arrangement of the sealing rollers maybe such that the elastic roller is located below the two steel rollers.
rollers. Arrangements are known according to which five or seven sealing rollers are employed with a corresponding larger number of sealing strips.
According to the present invention, the pressing devices the selected basic pressure, also sub ected to an additional pressure through a pressure conduit 8 which is connected to the pressure container 5. In order to avoid that the of a very high pressure. The basic pressure is produced by a spring urged or weighted lever 12 pivotally supported at 13 and connected to shaft 2a of roller 2 through the intervention of an arm 14 varied in conformity with the inner pressure of the pressure a'bsorber. In conformity with the invention, the sealing strips 4 are designed as elastic hollow bodies which, through a pressure conduit 9' likewise communicate with the inner pressure of the pressure absorber. The conduits 8" and 9 lead to a sealing device at the outlet end of the pressure absorber, which sealing device may correspond to that described above for the inlet to the pressure chamber 5.
It is, of course, to be understood that the present invention is, by no means, limited to the particular construction shown in the drawing, but also comprises any modifications within the scope of the appended claims.
What I claim is:
1. A pressure absorber arrangement I for webs of textile goods, which includes: tainer for receiving and containing a pressure medium, said pressure container being provided with an inlet and an outlet, a first conveying and sealing unit arranged at said inlet, a second conveying and sealing unit arranged at said outlet, each of said units including a plurality of roller means for passing a web of textile goods therethrough and respectively into and out of said pressure container, first means connected to at least one of said processing a pressure COI1-' 31161 means and continuously pressing it in the direction )ward the other roller means of the same unit, second leans connected to at least one of said roller means for messing the same in the direction toward the other rollr means of the same unit, said second means being presure fluid operable, means for supplying fluid to said )ressure fluid operable means comprising piston means ncluding a smaller first effective area connected with said iuid operable means and a larger second effective area, and means communicating with the interior of said pressure container for conveying pressure from the latter to said second effective area thereby to cause said first area to supply fluid at a pressure greater than the pressure in said container to said pressure fluid operable means.
2. A pressure absorber arrangement according to claim 1 in which inflatable sealing means are provided engaging said other roller means on the side thereof opposite said one roller means, said sealing means being connected to said first area.
3. A pressure absorber arrangement according to claim 2 in which said other roller means are located in the respective unit adj ac ent said container while said one roller 5 spective unit a of spaced para comprises a sing rigid rollers on the side djacent said contamer and comprise a pair llel rigid rollers while said one roller means le resilient roller engaging both of said thereof opposite said container.
