Description

Detailed Description of the Invention (Field of Industrial Application) This invention relates to a pre-drying device for a warp sizing machine, and in particular to a pre-drying device for a warp sizing machine, and in particular a pre-drying device for sizing and drying warps for yarn-dyed fabrics and then winding them onto a loom beam. Used in gluing machines.

(Prior art) In order to prevent undried sizing yarns from adhering to each other in a warp sizing machine, there is a known one in which cylinder drying is used for preliminary drying and final drying. For example, Japanese Patent Publication No. 57-43651 discloses a sizing tank equipped with dipping rollers and squeezing rollers in front of a creel for installing a warping beam, two series of upper and lower pre-drying cylinders, and one series of pre-drying cylinders. A finishing drying cylinder and a winding device are arranged in this order, and the warp threads drawn out in a sheet form from a small number of warping beams on a creel are dipped into a size liquid in a size liquid tank in a single sheet form using a dipping roller. After squeezing with a squeezing roller, it is divided into two upper and lower sheets, increasing the distance between adjacent warp threads.
The upper sheet-like warp is dried in the upper series of pre-drying cylinders.
In addition, the lower sheet-shaped warp yarns are pre-dried in the lower series of pre-drying cylinders to the extent that the sizing yarns no longer adhere to each other, and then they are combined into a single sheet again and finished dried in the finish-drying cylinder. A method is disclosed in which the material is applied and wound onto a pre-beam using a single winding device.

(Problems to be Solved by the Invention) In the conventional warp sizing machine described above, when the number of warp threads is relatively small, pre-drying is performed on the pre-drying cylinder at wide intervals such that the sizing threads do not come into contact with each other. However, on the other hand, the number of warp threads to be glued at one time is smaller than the number required for weaving, so in order to make a JFI machine beam, it is necessary to glue from multiple pre-beams wrapped with the above-mentioned glued threads. It was necessary to pull out the attached thread, overlap it, and rewind it around the loom beam.

On the other hand, if a large number of warping beams are set up to obtain the number of warps required for I2 weaving and the sized yarns are wound onto the loom beam, the sized yarns may come into contact with each other on the pre-drying cylinder. Therefore, when the yarns were separated using a dividing rod after finishing drying, the fluff of one yarn was often left behind on the other yarn. Therefore, for yarn-dyed fabrics, a large number of beams dyed in different colors by beam dyeing are mounted on a creel, and a mixture of yarn-dyed yarns of different colors is pulled out for sizing. If the yarn is made up of different colors, the fluff of the yarn of a different color will adhere to one of the yarns, which will stain the pattern of the finished fabric. When dyed threads were mixed, the stains mentioned above were noticeable and the product was sometimes inferior.

In order to prevent such contamination, the entire warp threads are divided into dark and light colored warp threads and one is pre-dried in the upper row and the other in the lower row, or the entire warp threads are mixed in color or density. Divide into 4 sheets accordingly.

It is sufficient to perform pre-drying separately using four groups of pre-drying cylinders, but when drying by winding sheet-like warps around multiple drying cylinders, it is easier to divide into two sheets rather than four. Good drying properties and improved drying efficiency. Therefore, it is desirable to perform pre-drying using the same gluing machine and selecting 2-sheet division or 4-sheet division depending on the number of colors.

In addition, when using a mixture of warp yarns with different counts, number of twists, twist directions, materials, etc. depending on the type of fabric, if all the warp yarns are wound around the same drying cylinder and dried, over-drying or under-drying may occur depending on the warp yarns. It is instructive to control the heating temperature for each cylinder and select 2-sheet or 4-sheet division for drying.

The present invention provides a pre-drying device for a warp sizing machine that is capable of pre-drying warp threads necessary for winding them around a loom beam into two or four sheets, and has good operability. be.

(Effects of the Invention) This invention is capable of converting the rotation direction of a total of four pre-drying cylinders arranged in two rows, one above the other, on the winding side between the forward direction and the reverse direction. The pasted sheet-like warp can be divided into two or four sheets and pre-dried. Therefore, there are up to 4 groups for each group with different warp colors, material number 1, twist, etc. 1. It can be pre-dried, and especially when used for sizing yarn-dyed yarns, it prevents fluff of a different color from adhering to the warp threads of the corresponding color and staining the pattern. Furthermore, since the pre-drying cylinders are arranged in two rows at the top, four each, there is no need to dig down into the floor during installation, and the height is lower than in the case where the cylinders are arranged in four rows above and below.

Threading the pre-drying cylinder is easy;
Moreover, the length of contact of the warp yarns with the predrying cylinder when dividing into four sheets can be increased.
