  • a normal warping system or a sectional warping system is conventionally employed depending on process conditions.
  • the normal warping method about several hundred or thousand warp yarns are wound directly around a warping beam.
  • warp yarns from a plurality of the warping beams obtained are wound all together around a weaving beam comprising several thousand warp yarns. Subsequently, the weaving beam thus obtained is supplied to a weaving machine for weaving.
  • the normal warping system is suitable for mass production in which a large number of warp yarns are warped but is not suited for small lot machining in many kind production.

  • Such a sectional warping machine is disclosed in, for example, the Unexamined Japanese Patent Application Publication (Tokkai-Hei) No. 7-118981 (p.2 to 5, Figure 1).
  • yarns are drawn out from a large number of (about several dozen to several hundred) yarn supplying packages disposed on a warping creel, to form a first band at a tapered end of a warping beam having a tapered winding surface. That is, the yarns are wound into one yarn layer having a width smaller than the axial width of the warping beam so that the yarns run obliquely to a shaft of the warping beam.
  • a second band is similarly formed adjacent to the first band. Moreover, this operation is repeated until a total number of yarns required are wound around the warping beam.
  • a sectional warping beam having a plurality of bands is formed.
  • one weaving beam is formed by simultaneously drawing out yarns from the sectional warping beam around which a number of yarns required for weaving have been wound.
  • one weaving beam can be formed using yarns from a plurality of sectional warping beams.
  • each yarn When a weaving beam is formed, each yarn may be wound up in a specified order in accordance with the sequence of the constituent yarns corresponding to the pattern of a woven fabric. In this case, yarns drawn out from yarn supplying packages installed on the weaving creel are sequentially passed through a reed and then wound around the beam.
  • the conventional sectional warping machine forms a sectional warping beam simply by drawing out yarns from yarn supplying packages of the same type in which the yarns are dyed in one color and winding them as warp yarns.
  • the conventional sectional warping machine can use a small amount of yarn supplying packages to form a weaving beam having a large number of warp yarns so as to deal with small lot machining in many kind production.

  • the knots in the respective yarns can be aligned with one another utilizing the slits.
  • An aspect of the present invention according to Claim 2 provides a warping machine that draws out yarns from a large number of yarn supplying packages and winds them around a beam, characterized in that the yarns are passed through a slit formed by a fixed member and a moving member that can contact with and separate from the fixed member, and when knots in the yarns drawn out from the respective yarn supplying packages are aligned with one another, an interval of the slit is set to be wider than the thickness of each yarn but is narrower than the thickness of the knot in the yarn, and when the aligned yarns are wound around the beam all together, the moving member is separated from the fixed member to open the slit.
  • all the yarn supplying packages can be set at mutually consistent respective winding start positions, by moving the moving member closer to the fixed member to form a slit and engaging the knots in the respective yarns with the slit. After the alignment, the yarns can be smoothly taken up by opening the slit.
  • the slit comprises paired rollers including a fixed roller and a moving roller, collars are installed at respective ends of one of the rollers, each of the collars having a larger diameter than the roller, and the paired rollers are tightly contacted with each other to form a slit, whereas the paired rollers are separated from each other to open the slit.

  • the slit is formed by placing the moving roller on the fixed roller so that the moving roller can fall freely, the moving roller having the collars installed at the respective ends and having a larger diameter than the roller.
  • the collar portions at the respective ends can be reliably contacted tightly with the fixed roller to make the gap of the slit uniform all over its axial length.
  • An aspect of the present invention according to Claim 5 is characterized in that neither the fixed roller nor the moving roller rotates.
  • the yarn can be stopped with the knot in the yarn sandwiched between the rollers.
  • An aspect of the present invention according to Claim 6 is characterized in that each of the yarn supplying packages are obtained by continuously winding predetermined lengths of yarns of various colors and types into the yarn supplying package in a longitudinal direction of the yarns while measuring the predetermined lengths.
  • the yarns from such yarn supplying packages can be wound around the beam by using mutually consistent mutually consistent respective winding start positions and maintaining mutually consistent mutually consistent respective sequences.

  • the moving roller 1 on which the collars 3 have been installed is abutted against the fixed roller 2 to form the slit S, constituting a gap T corresponding to the difference between the diameter of the collar 3 and the diameter of the moving roller 1.
  • the plural yarns Y of the plural yarn supplying packages P are passed through the slit S and drawn in the direction of an arrow 5. Then, a knot YN in the yarn Y is caught in the slit S to stop only that yarn Y because the slit S is wider than the thickness of the yarn Y but is narrower than the thickness of the knot YN.
  • those yarns Y having their knots YN engaged with the slit S are stopped and are no further drawn.
  • those yarns Y not having their knots YN engaged with the slit S yet continue to be lightly drawn out. In this manner, all the yarns Y have their knots YN engaged with the slit S and are the stopped at mutually consistent respective winding start positions.
  • the knots YN in all the yarns Y are aligned with one another (all the yarns Y are set at mutually consistent respective winding start positions) by drawing the yarns Y in the direction of the arrow 5. Then, the bundled yarns Y start to be simultaneously wound around the beam 4 in the direction of an arrow 6.
  • FIG. 2 shows a sectional warping machine W in which the knot aligning device 10 according to the present invention is employed.
  • Yarns Y are drawn out from the respective yarn supplying packages installed on a warping creel K.

  • the sectional warping beam 4A winds the yarns Y drawn out from the several hundred yarn supplying packages P installed on the warping creel K, into a predetermined band width L defined by the space reed 30. Once the yarns Y have been wound until a yarn length equal to one band is reached, winding for the next band is started. At this time, the several hundred yarns Y must be newly set at mutually consistent respective winding start positions (starting ends). To set the yarns Y at the mutually consistent respective starting ends, the moving roller 1 is lowered and abutted against and contacted tightly with the fixed roller 2.
  • knot aligning device 10 will be described with reference to Figures 3 and 4.
  • Each of the vertical guides 12, 13 is extended vertically from both sides of a supporting base 11.
  • a fixed shaft 2 is secured to the vertical guides 12, 13 so as to span them.
  • Each of the vertical guides 12, 13 has a U-shaped cross section and comprises a groove portion that is open in one direction.

  • the moving roller 1 abuts against the fixed roller 2 owing to its own weight.
  • the collars 3, installed at the respective ends of the moving roller 1 are tightly contacted with the fixed roller 2 to form the slit S of the gap T.
  • the slit S is parallel to the rollers 1, 2 all over its length in its axial direction. Accordingly, its gap T can be uniform all over its length in its axial direction. Therefore, the slit S is suitable for allowing a large number of yarns Y to pass through the slit S in parallel.
  • the gap T of the slit S must be varied depending on the thickness of the yarn Y.
  • the slit S can be changed so as to form the optimum gap T, by raising and removing the moving roller 1 from the U-shaped grooves in the vertical guides 12, 13, replacing the collars 3, installed at the respective ends of the moving roller 1, with ones of the appropriate size, and then installing the moving roller 1 in the vertical guides 12, 13 again.
