Definitions

  • the artificial filaments or fibers are, according to one method of manufacture, spun into a bucket, thus forming what is known as a cake of artificial fibers on the interior surface of the bucket.
  • it has been customary to reel the wet artificial fibers into skeins and then treat the skeined fibers to washing, desulfuring, bleaching and other steps, the fibers in skein form being less liable to inJury than in the cake.
  • Another method has been attempted, namely, to wash the fibers free from impurities while in the cake after placing an insert in the cake in order to maintain its shape.
  • the artificial fibers in this stage of manufacture i e., the wet stage,'
  • Figure 1 is a plan view of a cake of artificial fibers with a protective covering applied thereto.
  • Figure 2 is a vertical sectional view through a cake with the covering about to be applied thereto.
  • Figure 3 is a view similar to Figure 2 but showing the covering in final position on the cake, this figure being a vertical sectionthrough Figure 1.
  • the gist of my invention resides in providing a rotective covering for the cake of artificial bers at this stage in the process of manufacturing the fibers.
  • the covering I should be of a material which will protect the cake from the ill effects of handling and which will also keep away substantially all of the dust and impurities which are in the air.
  • the material forming the covering must be such as to permit the passage of water or other liquid therethrough and to permit liquid to be passed from the cake.
  • a fabric such as cheese-cloth forms a satisfactory material for such a covering, although other materials may be used if found satisfactory.
  • the covering is formed by taking a length of fabric as indicated by the numerall and placing it around a cake 2 in the approximate manner shown in Figure 1, so that it will overlap at 3 to completely surround the cake.
  • the length of fab- IlC is wider than the depth of the cake and preferably the lower portion 4 of the covering below the cake is longer than the upper portion 5 above the cake.
  • This top portion 5 s brought around over the cake as indicated in Figure 3.
  • the lower portion 4 is then brought over the top of the cake and up through the interior thereof, it being noted that the lower edge 7 overlies the top edge 6.
  • the lower portion is pulled completely through the cake, thus insuring a continuous covering for the interior.
  • the cakes are usually washed while hanging upon rods,
  • the step cake of artificial fibers which comprises covering it with a fabric.

  • the method of treating a cake of artificial fibers which comprises providing it with covering in the method of treating anessnoa 7 aprotective covering which will permit the passa gle1 QfJiqIuids.
