Definitions

  • the present invention relates to the treatment of artificial silk wound in package form and more particularly to such packages which have no internal circular supports at the time of the novels been entirely satisfactory due to the fact that during drying, contraction of the threads takes place and. various degrees of resistance to contraction are set up in the package which permits the inner convolutions to contract more thanthe outer convolutions. This is an obvious characteristic because the inner convolutions themselves prevent full contraction of the outer convolutions.
  • various processes of drying have been devised and probably the most satisfactory is that in which the drying operation follows the so-called inside outside drying type.
  • This mode of drying is effected by introducing, the drying 0 medium such as warm air into thread-free space within the package and continuously passing it therethrough so that the layers of thread dry progressively from the inside to the outside. This results in the inner convolutions contracting and leaving space for the outer convolutions to fully contract.
  • the drying 0 medium such as warm air
  • Such a process and apparatus for conducting the same is more fully described and claimed in copending applications which have been assigned to the assignee in the present applilo cation and bearing the following identifications: Serial No. 732,715, filed June 2'7, 1934; Serial No. 736,939, filed July 25, 1934; Serial No. 740,018, filed August 15, 1934.
  • an improvement might be made, as it is impossible to prevent a small amount of the drying medium to contact the outer portions of the thread package during the initial drying. This causes a slight unevenness of contraction within the thread package.
  • This invention is concerned with a specific manner of deforming packages and a device for accomplishing the same. It is, in effect, an improvement over the foregoing patent.
  • the invention relates to,the treatment of packages collected on bobbins or to packages spun into a centrifugal bucket.
  • bobbin spun silk If bobbin spun silk is to be treated, it may be first washed, desulphurized and dried on the original bobbin and thereafter rewound and twisted onto a second holder, which holder may have a cotton sack thereon.
  • the twisted package is rewetted and bleached either on the holder or after it has been removed therefrom with the cottonsack.
  • the package is then in readiness for treatment according to the present invention.
  • the package In the treatment of packages of centrifugally spun silk, the package is washed, desulphurized and bleached and is-in readiness for the novel treatment.
  • Figure 2 shows a number of packages of artificial silk packed in a hydro-extractor having the triangular insert incorporated in each of. the said packages;
  • Figure 3 exemplifies the condition of the pack ages after the hydro-extraction operation.
  • Figure 4 shows the packages of silk in a drying frame with the forms removed in readiness for the drying operation.
  • the invention may be more readily understood by reference to the drawing wherein I indicates a suitable type hydro-extractor for extracting the excess moisture from packages of silk 2.
  • packages have inserts 3 contained therein, the purpose of which will hereinafter be more fully explained.
  • the inserts are constructed of any suitable material such as wood, bakelite and the like and are preferably hollow to reduce the weight thereof.
  • the size of these inserts is so chosen that they are slightly smaller than the space defined by the interior of the packages and they may be of any suitable length to support several packages thereon. Whereas it has been determined that excellent results are obtained by the use of an insert having the conformation of an equilateral triangle, it is within the scope of this invention to provide inserts of other shapes such as squares.
  • the wet packages are placed in a normal type hydro-extractor and triangular inserts fitted within the interior of each of the packages.
  • the packages are hydro-extracted for a sufficient time to eliminate the excess moisture and this may be determined by noting when the water has ceased to drip from the outlet of the extractor.
  • the centrifugal force set up within the extractor causes the packages to shape themselves to the contour of the triangular inserts and an exceedingly uniform triangular package is produced.
  • the packages are removed from the container and the inserts taken out of each package.
  • the deformed packages are placed in a drying tray so that each side of the package is in contact with one side of an adjacent package. It is obvious that if other shapes are desired, the packages may still be placed in a drying tray in a geometrical pattern. It has been found that the deformed packages of silk are in such close relationship that substantially inside outside drying may be accomplished when the top and bottom of the tray contain galvanized wire covered with cotton cloth.
  • the drying may also be carried out in a box-like container having holes in the top and bottom to correspond with the holes in the deformed packages.
  • a process of treating unsupported packages of artificial silk which comprises positioning the same in a hydro-extractor, incorporating polygonal shaped inserts Within each package, hydroextracting the packages whereby the excess moisture is removed with the simultaneous deformation of the packages to a shape conforming with that of the said insert.
  • a process of deforming unsupported packages of artificial silk which comprises positioning the packages on polygonal inserts in a hydroextractor and subjecting the packages to centrifugal action to thereby cause the same to assume the shape of the inserts while eliminating excess moisture therefrom.
  • a process of automatically deforming packages of artificial silk which comprises disposing unsupported packages onto triangular supports, arranging the same within a hydro-extractor, hydro-extracting the packages and deforming the same simultaneously by centrifugal force.
  • a process according to claim 3 which further includes the removal of the triangular shaped packages and geometrically arranging the same in a drying container to permit inside outside drying thereof.
