Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for winding selvage yarn in a partial warping and sizing machine.

In a partial warp sizing machine, a group of warp threads pulled out from a creel are sized, dried, and wound around a partial warp drum, and several groups of sewing threads are sequentially wound adjacent to the partial warp drum.

Then, a required number of selvage threads are wound adjacent to the outer sides of the first group of warp threads to be wound first and the final group of warp threads to be wound last on the warping drum. The required number of partial warping drums, which have selvage yarns on both sides and several groups of warp yarns wound between them, are manufactured.
The method for winding the selvage threads is to first place the required number of selvage thread cheeses on one side of the creel, pull out the selvage threads from the cheeses, and at the same time pull out the first group of selvedge threads from the warp thread cheeses. Draw out the selvage yarns, glue and dry the selvage threads and warp threads together, and wind them onto a warping drum.Then, move the selvage thread cheese to the opposite side of the creel, and when winding the final group of warp threads, The selvage thread is pulled out from the selvage cheese, the selvage thread and the warp thread are glued together, dried, and wound onto a partial warping drum.

Furthermore, when winding the first group of warp threads onto the second partial warping drum, the selvage thread cheese is moved to the opposite side of the creel to pull out the selvage threads. However, in this conventional method, each time the selvage thread is wound, the selvage thread cheese is moved to the opposite side of the creel, the selvage thread is pulled out from the cheese, and the selvage thread is passed through the creel's many guides and the coin needle. During the process, the selvedge yarn must be passed sequentially through a large number of rollers in the lake section and the drying section to be forwarded to the partial warping drum, and the selvedge yarn must be reloaded into the warping and sizing machine each time, which requires a great deal of effort. Furthermore, when the selvage yarns are forwarded, the warp yarns are also forwarded together, resulting in a large amount of wasted warp yarns. Therefore, a method was invented in which the selvage thread is allowed to escape to the side of the warping and sizing machine while the selvage thread is not being wound, thereby preventing the selvage thread from being fed forward.

As shown in Japanese Patent Publication No. 48-981, this release method involves gluing and drying the warp yarns of the first group and the selvedge yarns placed next to them together, and winding them around a partial warping drum. After that, move the selvage yarn on each roller onto a small roller with a flange that is rotatably installed at the end of the roller, cover the selvage yarn in the sizing section with a tube to prevent the adhesion of size liquid, and then move The selvage threads are moved onto an isolating member provided over the end of the drying cylinder to prevent forward feeding of the selvage threads, and when winding the last group of warp threads, the side of the warping and sizing machine is The selvage threads that were waiting in the past are returned to their original positions, the selvage threads and the warp threads are forwarded together, and the selvage threads are wound around the outside of the last group of warp threads. However, in this conventional method, after winding the warp yarns of the first group and before winding the warp yarns of the final group, the selvage yarns set in the partial warp sizing machine are moved to the side, and the sizing liquid is removed. Since the anti-adhesion tube must be attached and detached, it takes a lot of effort.

Furthermore, since the selvage threads are always placed on the same side of the partial warping and sizing machine, when winding the warp threads of either the first group or the last group, the selvage threads are always located just before reaching the warping drum. The warp threads have to be crossed at the position of , making it difficult to advance the selvedge threads.The purpose of the present invention is to improve the drawbacks of the conventional method as described above, and to provide a partial warping glue that does not require much labor. An object of the present invention is to provide a method for winding selvage yarn in a winding machine.

Next, examples of the present invention will be described. As shown in FIGS. 1 and 2, a partial warping and sizing machine that implements the selvage yarn winding method of this example is provided with a sizing section 2 at the front of a creel 1, and a sizing section 2 at the rear of the creel 1. A size box 5 containing a coin 3, a guide roller 4, a size box 6, a dipping roller 7, and two pairs of squeezing rollers 8 and 9 are provided, and a drying section 10 is provided in front of the pasting section 2.
A rear guide roller 1, a large number of drying cylinders 12, and a front guide roller 13 are provided in the drying section 10, and in front of the drying section 10, a widthwise strip 14, a side roller 15, and a partial warping drum 16 are provided.

Furthermore, on the front lower side of the front guide roller 13 of the drying section, there is a mark "
A beam 17 and a machine 18 are provided for the selvage yarn. When carrying out the selvage yarn winding method of this example, first, a required number of selvage thread cheeses (not shown) are placed on one side of the creel 1, and the selvage threads are pulled out from the cheeses, and at the same time, the warp thread cheese (not shown) of the creel 1 is pulled out from the creel 1. As shown in FIG. The first group of warp threads and selvage threads A are passed through a long neck roller 5 and wound around one end of a warping drum 16 to a required warping length.

Next, the warp yarns and selvage yarns of the second group are glued and dried on the same machine as the warp yarns of the first group, and as shown in FIG. While the warp yarns A of the group are wound in a lengthwise manner adjacent to each other, the selvage yarns E pass through the front guide roll 13 of the drying section and are then wound in the warp i as shown in FIGS. 1 and 3.
8 and then wound onto a selvage thread beam 17. When winding the warp yarns after the third group, the selvage yarns E are similarly attached to the selvage yarn beam 1.
7, and before winding the last group of selvage threads or when the winding length of the selvage threads reaches the required length, the selvage threads E are cut at the rear position x of the glued part 2. When winding the last group of warp threads, as shown in Fig. 4, the selvage thread beam 1
7 is placed behind the selvage yarn winding position of the partial warping drum 16, and the selvage yarn E unwound from the selvage yarn beam 17 is forwarded together with the final group of warp yarns, and Then, the final group of warp threads and selvage threads Z are wound up to a required warping length, and winding is completed for the first partial warping drum. When subsequently winding onto the second partial warping drum, as shown in FIG. The selvage thread E unwound from 17 is forwarded together with the first group of warp threads Y, and the first group of warp threads and selvage threads A' are wound up to the required warping length at one end of the partial warping drum 16.
Thereafter, as in the first partial warping drum,
Repeat winding of each group of warp threads. The third and subsequent partial warping drums are wound in the same manner.

Note that a conventionally known means is used for winding and unwinding the selvage thread on the selvage thread beam. In the illustrated embodiment, the warp threads are drawn out from the cheese, but they may also be drawn out from the warping beam.

The selvage yarn winding method of the present invention involves winding the glued and dried selvage yarn together with the warp yarn onto a selvage yarn beam, and each time the selvage yarn is wound onto a partial warping drum, the selvage yarn beam is rotated. The selvage yarn is placed behind the selvage winding position of the partial warping drum, and the selvage yarn unwound from the selvage beam is wound onto the end of the partial warping drum together with the warp yarn, so the selvage yarn is removed every time the selvage yarn is wound. This method requires much more effort than the conventional method of reloading the machine into the partial warping and gluing machine, or by moving the selvedge threads installed in the partial warp and gluing machine to the side and attaching and detaching the size liquid adhesion prevention tube. It doesn't hang.

Furthermore, each time the selvage yarn is wound onto the partial warping drum, the selvage beam is placed behind the selvage winding position of the partial warping drum, so that the selvage yarn crosses the warp just before it reaches the partial warping drum. Unlike the conventional method, the selvage thread is advanced smoothly and effortlessly.
