Description

[Detailed Description of the Invention] The present invention relates to a bobbin for winding fiber threads for dyeing, heat treatment, etc.

In particular, when frusto-conical or cone-shaped packages are stacked on a spindle, the spacers previously used are unnecessary and the number of packages processed per spindle is increased.

Figure 1 shows an elastic wire 1 bent by alternating directions in the axial direction, and adjacent bent portions 2 of the large diameter portion partially overlap each other so that adjacent wires in the axial direction overlap. The bent part of the small diameter part of the cone-shaped elastic body formed by the above process is fixed to the fixed diameter ring 5, and the overlapping part of the large diameter part is partially fixed as shown in 3, and the part is connected with the band 4. It is formed into a cone shape by changing the length of the bent portion of the larger diameter portion or by changing the length of the overlapping portion.

Instead of fixing, a recess may be made in the bent portion and the bent portion 2 may be connected with a continuous wire so that it does not move.

In FIG. 2, contrary to FIG. 1, all the overlapping portions of the large diameter portion are fixed, and the bent portions are fixed and connected so that the small diameter portion can be contracted.

FIG. 3 shows the elastic body shown in FIG. 2 in which the small diameter portion and large diameter portion are partially fixed at the overlapped portions of the bent portions so as to be contractible, and partially connected with a band.

FIG. 4 shows an elastic body similar to that shown in FIG. 3, formed into a cylindrical shape so that it can be contracted.

Talk about the action.

After winding yarn around the bobbin shown in FIG. 1 to form a cone package, the bobbin is moved to the smaller diameter side of the package and the cone package is inserted into the spindle.

The winding thread moves toward the large diameter side due to the contraction of the large diameter part of the bobbin, and the small diameter part of the bobbin enters the large diameter part of the upper bobbin.At 0, the upper surface of the cone package touches the lower surface of the upper package, and the packages are stacked without any gaps.

Also, since the small diameter portion has a constant diameter and matches the spindle diameter, the packages can be stacked correctly and no spacer is required.

Further, when the thread is wound on the bobbin shown in FIG. 2, the wound thread may be moved by contracting the small diameter portion so that the small diameter portion after shrinking matches the spindle diameter.

For yarn that shrinks due to heat treatment, the yarn is wound around the bobbin shown in FIG. 3, and after the small diameter portion is shrunk together with the yarn to the diameter of the spindle by heat treatment, the same procedure as in FIG. 1 is carried out.

Alternatively, after the winding yarn has been moved, it may be inserted into a spindle and heat treated.

If the bobbin of the present invention is configured not only in a cone shape but also in a cylindrical shape with a contracting diameter as shown in Fig. 4, it is effective as a bobbin for parallel cheese with threads that shrink by heat treatment, and the overlapping part of the bent part is fixed. Because of this, the cylindrical shape is stable.

Since the diameter after contraction is regulated by the number of fixed points, the small diameter portion after contraction can be determined to match the spindle diameter.

Furthermore, even if the small diameter portion shrinks, if the maximum diameter is the same as the spindle diameter, it can be used for threads that do not shrink due to heat in the same way as those with a constant diameter.

Note that the wire used is a straight wire that is bent vertically or horizontally into a wavy shape.

Alternatively, a similar elastic body may be formed of a thin plate-like material.

The present invention is made by bending an elastic wire in a zigzag pattern in the axial direction of the bobbin, reducing the distance between adjacent bent parts, and fixing and connecting the overlapping parts of an elastic body with overlapping bent parts. It is easy to manufacture, low-lying, and has high elasticity because the distance between the bent parts is shortened.

The bobbin of the present invention also eliminates spacers when stacking cone packages, increasing the number of packages per spindle.
