Definitions

  • a laminated textile yarn core with a breakaway stringup slot features a circumferentially disposed groove in the outer surface of the core for initiating stringup and a second Circumferentially disposed groove on the inside that is longitudinally inward from the stringup groove.
  • the two grooves have overlapping depths to cut one common bond line between layers of the core.
  • the incorporation of the second groove permits removal of the section of the core between the stringup slot and the end of the core by shearing the ply bond layer between the stringup slot and inner groove.
  • Modern high speed production methods entail efficient processes in both the initial winding and in the unwinding of textile yarns from packages during subsequent processing.
  • Of particular usefulness in the initial winding operation have been textile. cores of the types disclosed in Sowell, U. S. Pat. No. 3,284,023 and in Heatherly, U. S. Pat. No. 3,103,305 which use traps and/or a circumferential V-groove in the core end to effect the initial engagement of the yarn therewith. Yarn placed in position to enter the groove during yarn stringup is engaged by the groove or trap and is quickly severed, the initial windings thenforming a transfer tail for use in subsequent processing.
  • the core is fabricated from spirally wound paper or paperboard sheets using an adhesive to bond the paper plies 20 at glue lines 22 as shown in FIG. 3.
  • the grooves l2, 13 are cut into the surfaces of the core in a plane perpendicular to the axis of the core, are thus parallel to each other and separated by the distance x, and are generally of similar'depth, the depths being such that they cut at least one common glue line 24 between plies. ,
  • the core may then be sheared along this glue line at the desired time.
  • the distance x between grooves is selected so that the core has sufficient strength for performing its stringup and winding functions, but also so that the end may be sheared and removed when desired by twisting, pressing, pulling, or by the preferred means of wedging, usinga suitable tool in conjunction with the hole 18. Removal of the core end frees the transfer tail for easy tie-in in a continuous unwinding operation and. eliminates the groove 12 which can catch or snag theyarn during yarn transfer. It has been found that the useful rangefor dimension'. ⁇ - for a core with a 2 inch inner diameter and with a wall thickness'of 5/32 inch should not be less than 0.030 inch to maintain the structural integrity of the core wall, and for ease of removal,
  • FIG. 1 is a cross-sectional'view of a portion of a core constructed in accordance with the invention.
  • FIG. 2 is an isometric view of an alternate embodiment of the invention.
  • FIG. 3 is a cross-sectional view through 33 of FIG. 2.
  • FIG. 4 is a side view of a being removed. I
  • core 10 is a hollow cylindrical body containing grooves 12 and 13 placed near core end 14.
  • Groove 12 is located in the outer surface I5 ofthe tube and groove 13 is located in the inner surface 16 of the tube.
  • Groove 13 is located longitudinally inward of groove 12 by a distance .r.
  • the contour of the groove 12 encircling the outer surface of the core is generally V-shaped and of the type disclosed in Heatherly. US. Pat. No. 3,103,305 comprising a wide portion and a narrow portion.
  • core showing the core end should not exceed 0.250 inch. Dimension will vary depending-on the strength of the glue/paper bond and with the possible glued area between grooves which is related directly to the diameter of the core.
  • the preferred means for removing the core end is by prying with a tool comprised ofa handle 26 and a blade 28 with an end contoured to fit hole 18.
  • the end of the blade is inserted into the hole from'the-inside of the tube and pivoted across the opposite edge of the tube as indicated in FIG. 4.
  • the end, sheared along a glue line, comes'cleanly away from that core section carrying the yarn package, leaving no groove or end roughness to snag an unwinding threadline.
  • a laminated yarn core comprising superposed bonded layers and having outer and inner surfaces, said core having a circumferential stringup groove in its' outer surface located adjacent one of its ends to effect the initial engagement of the yarn on the core, said core also having a circumferential groove in its inner surface located longitudinally inward from said stringup groove, said grooves being of such a depth as to cut one common bond line between said layers.
  • the yarn core of claim 1 said yarn core having a diameter of about 2 inches,'thegroove on t'heinne'r surface being located longitudinally inward from the stringup groove a distance of. from'about 0.030 inch to one common adhesive line between said layers.
