Definitions

  • Figure l is a schematic view in side elevation of a running point of a creel incorporating the apparatus of the present invention and illustrating the processes of the present invention
  • Figure 2 is a view similar to Figure 1 illustrating a modified type of apparatus
  • Figure 3 is a view also similar to Figure 1 but illustrating a further modified type of apparatus
  • Figure 4 is a view in front elevation of the apparatus of Figure 3.
  • Figures 5 and 6 are views in elevation to an enlarged scale for the purpose of demonstrating the direction of twist of crepe threads, Figure 5 illustrating a Z-twist and Figure 6 an S-twist.
  • the reference numeral l0 refers to asta- 0 tionary, non-rotating wound body of twisted rayon thread such as crepe.
  • the body I0 is shownvdiagrammatically but is intended to indicate bobbins, conical packages and other forms of wound twisted rayon thread of circular crosssection.
  • the numeral Il represents a warping beam at a point remote from the running point at which the thread body I0 is located.
  • the thread body I0 is supported in a stationary, nonrotating manner on a creel spindle I2 diagrammatically indicated in Figures 1, 2 and 3.
  • the beam ll is rotated at a peripheral speed of several hundred meters a minute, thread is drawn overhead from the body I0 and is wound on the beam. It will be understood that While but a single running point is illustrated in the Figures l, 2 and 3 of the drawings, a large number of such points are contemplated as is customary in the construction of creels.
  • the numeral I3 represents a thread guide that is prevent entanglement with the thread guide.
  • the numeral Il represents a brake combined therewith. This arrangement alone is benecial in preventing tangles and the like but it has ben found, as a part of this invention, that superior results are attained if the thread is taken of! overhead in such manner that the twist imparted thereto during the ballooning incident to unwinding is in the same direction and additive to the original twist of the component thread of the package I0.
  • the high twist to which the initially parallel laments are subjected may be in either of two directions. In one direction the twist is called a Z-twist and in the other it is called an S-twist. These twists are illustrated in Figures 5 and 6.
  • the yarn When the yarn has been wound on a cylindrical bobbin it can be withdrawn overhead from either direction.
  • disc I6 shown in Figure 2, said disc being associated with a thread guide such as I1.
  • disc I6 may have a at or conical shape and tends to baille the balloon in such a way as to
  • a unitary structure such as IB may be used.
  • This structure consists of a disc having a central tone at I9 which func- If desired, the opening at I9 may be dened by some special material
  • the discs I8 are so chosen with respect to diameter ,Y that when the creel frame is filled, adjacent discs I8 almost touch one another. In this regard becoming entangled on the left side of the disc,
  • the thread guide must be disposed close to the bobbin or package which is being unwound, the distance between the end of the bobbin adjacent the guide, and the guide being less than the radius of the fully wound bobbin at that end. In actual measurement thm distance is ordinarily two centimeters or less.
  • the thread guides and/or discs may be arranged for sliding movement toward and from the end of the bobbin.
  • the improvement that comprises supporting in a stationary, non-rotating unwinding position, a wound body of twisted rayon thread of circular cross section, drawing oif thread from an end of said wound body while augmenting the existing twist of the component thread thereof, and guiding succeeding portions of the unwound thread at a point spaced axially from the draw-off end of the wound body a distance that is less than the radius of the fully wound body at its draw-off end.
  • the improvement that comprises supporting in a stationary, non-rotating unwinding position, a wound body of twisted rayon thread of circular cross section, drawing oil thread from an end of said wound body while augmenting the existing twist of the component thread thereoi, and passing succeeding portions of the unwound thread through a small circular guiding zone located at a point spaced axially from the draw-oil end of the wound body a distance that is less than the radius of the fully wound body at its draw-off end.
  • the improvement that comprises supporting in a stationary, non-rotating unwinding position, a wound body of twisted rayon thread of circular cross section, drawing off thread from an end of 'said wound body while augmenting the existing twist of the component thread thereof, and guiding succeeding portions of the unwound thread at a point spaced axially from the draw-off end of the wound body at a distance that is less than the .radius of the fully wound body at its draw-oil end, and conning the axial extension of the ballooning thread to a distance from the unwinding end of the wound body not greater than the distance of said guiding point therefrom.
  • apparatus for the warping of rayon threads which includes means forsupporting in a stationary, non-rotating unwinding position, a wound body of rayon thread of circular crosssection, and draw-oil device for drawing thread axially from one end of a wound body supported on said means, the improvement that comprises thread guiding means disposed in the thread path between the wound body and said draw-off device a distance from the draw-oil end of the wound body that is less than the radius of the fully found body at its draw-off end whereby high spetei warping ci' high twist thread may ⁇ be e!- !ec d.
  • apparatus for the warping of rayon threads which includes means for supporting in a stationary, non-rotating unwinding position, a wound body of rayon thread of circular crosssection, and draw-off device for drawing thread axially from one end of a wound body supported on said means, the improvement that comprises /a-disrrhaving a central thread guiding aperture,
  • said disc being" disposed in a plane normal to the thread path between said Wound body and said draw-off device a distance from the draw-oil' end oi' the wound body that is less than the radius of the fully wound body at its draw-olf end whereby high speed lwarping of high twist thread may be eifected.
  • apparatus for the warping of rayon threads which includes means for supporting in a stationary non-rotating unwinding position, a wound body of rayon thread of circular crosssection, and draw-off device for drawing thread axially from one end of a wound body supported on said means, the imp-ovement that comprises thread guiding means disposed in the thread path between the wound body and said draw-off device a distance from the raw-01T end oi' the wound body that is less than the radius of the fully wound body at its draw-off end, and disc means surrounding said guiding means whereby high speed warping of high twist thread may be efi'ected.
  • apparatus for the warping of rayon thread which includes a plurality of closely spaced means, each for supporting in a stationary, nonrotating unwinding position a wound body of v rayon thread of circular cross-section, and a common draw-ofi device for drawing thread axially from the same end of each wound body supported on said means, the improvement that comprises a plurality of disks each having a substantially central thread-guiding aperture therein, each of said disks lying in the thread path between each of said wound bodies and said draw-oil device a distance from the draw-off end of each Wound body which is less than the radius of the respective fully wound body at its draw-off end.
  • diameter of said disks being almost equal to the distance between adjacent supporting means.
