Definitions

  • This invention relates to a process for handling an unsupported package of thread in preparation for fluid treatment. More particularly the invention relates to the treatment of bucket cakes in the manufacture of artificial thread.
  • the artificial thread is withdrawn from the spinning baths and is carried in the form of a thread into the central portion of a bucket rotating at high velocity.
  • the thread is formed on the inside of the bucket into a cylindro-conical cake. After the cake has reached a given size it is removed from the bucket and purified. It is desirable to purify in the cake form but this has not been satisfactory with large and thick cakes because of the long time required; consequently, large, thick cakes have been usually reeled into skeins, washed, desulfured, and bleached, and then wound on spindles for transportation to the place of use.
  • the objects of the invention are accomplished by softening the bucket cake without causing substantial derangement of the interlacing structure of the threads.
  • This softening may be accomplished by kneading, by elongating, or by deforming the cake in any suitable manner.
  • the term soften is herein used to cover any method wherein a yarn package is subjected to mechanical treatment designed to soften it or to open the interlacing structures of the threads. In no case, of course, will the kneading or other softening be continued to a degree such that difiiculty will be experienced in unwinding the thread from the treated cake.
  • Figure 1 is a side view of one form of elongating mechanism in operation.
  • Figure 2 is an end view of the same mechanism.
  • Figure 3 is a diagrammatic showing of a cake before processing.
  • Figure 4 is a diagrammatic showing of the same cake after processing.
  • a bucket cake (4) is taken from the spinning bucket and is placed over a roller (2) and a guide roller (3).
  • a presure roller (I) is then moved to a position to bear upon the outside of the cake and one, or two, or all of the rollers are driven to revolve the cake until it is sufliciently softened and the interlacing of the threads is sufficiently opened 1931, Serial No. 524,308
  • My invention makes the processing of bucket cakes, whether of large or small dimensions, better and quicker because the opening of the interlacing of the threads permits the treating liquids, whether they be purifying, dyeing, washing, or other liquids, to penetrate the cake with greater facility. This is true whether a drip method of processing, or a vacuum method of processing, or a centrifugal method of processing is adopted.
  • the step which comprises mechanically working and elongating the bucket cake by passing the same be- 7 tween pressure rollers, and thereafter processing the cake by fluid treatment.
  • the step which comprises mechanically working and elongating the bucket cake by passing the same between pressure rollers, one of said rollers contacting the inner periphery of the bucket cake and 15 another of said rollers contacting the outer pe- .riphery of the said bucket cake, and thereafter processing the cake by fluid treatment.
