Filed March 9,A 1931 Patented Aug. 9, 1932 STATES HENDRIK NOLET, OF ARNHEM, NETHERLANDS, ASSIGNOR TO ALGEMEENE KUNSTZIJ DE I UNIE N. V., F ARNHEM, NETHERLANDS Y APPARATUS FOR TREATING CHEESES WITH LIQUIDS Application filed March 9, 1931, Serial No. 521,331, and in the Netherlands February 18, 1930.

|Ihis invention relates to a process for treating crosswound bobbins or cheeses, more particularly of articial silk, with'liquids. By means of the invention artificial silk may be produced forthwith in a wound form such as is usual in commerce, and in this wound form may be subjected to the various after-treatments. v

The purpose of the invention consists in the fact that the artificial silk is washed, bleached, desulphurized, and if necessary dyed without it being necessary previously to re-spool or reel the product. In-this way a very considerable saving of work is proi duced. Furthermore, the danger of damaging the yarn is considerably diminished, if not eliminated altogether.

According to this invention the cheeses are arranged with the aid of intermediate members, in a tube, which may be divided into longitudinal direction, and are there subjected to the various liquid treatments. Y

According to the invention intermediate members may be used, which may be provided with perforated tubular portions or flanges which proj ect wholly orpartially into the central opening of the cheeses.

Further, according to the invention, the liquid may be forced or drawn through the cheeses either from the inside to the outside, or vice versa, or alternately from the inside to the outside and from the outside to the inside.

'Ihe process according to the invention may also be carried out in such a Way that the cheeses are immersed partially or wholly in the liquid and rota-ted about their longitudinal axes.

Finally, the invention embraces a modificatiton in which the cheeses are jacketed with a permeable fabric before the treatment with liquid takes place.

For the purpose of elucidating the inven- Y tion a detailed description of the new process is herewith appended, said description referring to the accompanying drawing in which one of the many modifications of the invention is given as an example.

In the accompanying drawing l, l, 1 are the cheeses which, for example, are spun on .a

suitable permeable layer 2, e. g. of cotton. l

The various spools are arranged in the tube 3 which is provided with perforations 4. In order to facilitate the introduction of the cheeses into the tube, the latter may consist, for example, of two parts divided along an axial, vertical plane as at 8, forming edges which fit on to one another in a longitudinal direction and may be secured to one anther in any suitable manner. The securing means have here been shown as an annular cap 9 tting over the top, and a cup-shaped base 10 closing the bottom end of the tube 3. The cap and the base may be threaded on the ends of the tube or only pushedon tightly. Suitable intermediate members are arranged between the cheesesl, l which, according tothe constructional example shown, are provided with tubularprojections 6 which project into the cheeses; rThe intermediate Vmembers 5 are 'provided with a central opening through which the liquid can flow. If necessary means may be provided to maintain the intremediate members 5 at definite distances from one another.`

After the introduction ofthe cheeses into the perforated tube 8, the halves of the tube are well secured to one another, whereby the `cheeses aresomewhat pressed together in frombelow, the tube being closed at the top" in the form of cheeses at the start does notfr 7 any longer have to be unwound, reeled or subjected to similar operations. i f

The employment of the process according to this invention, therefore,not only implies a considerable protection of the artiicial silk during the treatment With liquid Y but it also involves a substantial saving in costs. 1

vWhat I claim is:

or cheeses, consisting of a tube split into tvvo parts longitudinally, intermediate pieces having a central bore and perforated tubular projections on these intermediate pieces, the height of which is less than half the height of the coils or cheeses.

v9. An apparatus for Washing cross coils or cheeses, consisting of a perforated tube ydivided in the longitudinal direction, intermediate pieces having a central bore, which are provided on both sides With perforated tubularprojections, a pervious layer inside the coil and a non-perforated connecting oue arranged at the end of the perforated tu e.

In testimony whereofI I have signed my name to this specifica-tion. Y Y

' HENDRIK NOLET.

l. An apparatus for Washing cross/coils Y or cheeses, consisting of a perforated tube, the `inner diameter of which corresponds roughly to the outer diameter of the coils, and intermediate pieces With a central bore,

which are inserted between lthe end faces of the coils.

2. An apparatus for Washing cross coils vor cheeses, consisting of a perforated tube,

the inner diameterof Which"roughlyv corresponds to the outer diameter of thecoils, and intermediate pieces having la centralk bore, which are inserted between the end faces of the coils, and means, which arev adapted, to pass the treating fluids through the coils and through the wall of the perfo# rated tube. j .v

3, An' apparatus forwashinfr cross coils or cheeses, consistingV of a'perforated tube divided in the longitudinal direction, intermediate pieces having a central bore and Y tubular projections on the same, the diameter of which roughly corresponds tothe diameter of the interior of the coils.

a. An apparatus as claimed in vclaim 1, in which the perforated tube is closed 'at one endA and provided at the other end With an aperture. Y

5. An apparatus for Washing cross coils or cheeses, consisting of a perforated tube closed at one end and a non-perforated connection tube located att-he other end of the tube, Which connection tube is suitable fori connecting the interior of the tube with a suction device. j

6. VAn apparatus as claimed in claim 3, in which the tubular projections located on the intermediate pieces are perforated.

7. An apparatusfas claimed in claim`3, in which the height of the tubular projections, arranged on the intermediate pieces is less than the half height of the coils placedv thereon.

8. An apparatus for Washing crossl coils
