Description

[Detailed description of the invention] <Industrial application field> This invention is a device for aligning both ends of warp yarns during drying in a sizing machine, more specifically, a device for aligning both ends of warp sheets during the drying process using a simultaneous sizing method. The present invention relates to a device for controlling the spread of nearby yarns in the width direction of the sheet, drying the yarns at both ends of a warp sheet without disturbing them, and preventing any inconvenience in subsequent processes.

[Technical Background of the Present Invention] Generally, in the case of spun yarn, from the sizing process to the drying process, several warp yarns at both ends of the warp sheet are It is well known that yarns tend to spread outward in the sheet width direction. When the threads at both ends of the sheet spread outward in this way, the threads are dried while being entangled during the drying process, and as a result, excessive tension is applied to the spread threads in the next dividing process, causing thread breakage. There are various disadvantages such as the tension being loosened when the wire is wound around the beam.

However, no technology has been disclosed to date to correct this inconvenience.

<Purpose of the invention> This invention restricts the yarns near both ends of the warp sheet from spreading outward in the width direction of the sheet during the period from the pasting process to the drying process as described above.
It is an object of the present invention to provide a device for aligning yarns at both ends during drying in a sizing machine, which does not cause the above-mentioned inconvenience.

<Basic structure of the device> In order to achieve the above object, the basic structure of this device is to control the lower side, that is, the spread, of both ends of the warp sheet S, as shown in FIGS. 1 and 2. Warp sheet S from a predetermined position below the end threads.
At least one pair of guide members 1 are provided at both ends of the warp sheet, and the guide members 1 are inclined at a predetermined angle toward the outside and upward in a direction that intersects (preferably perpendicular to) the yarn ends of the warp sheet.

<<Example>> The guide member 1 is attached to a holder 3, and in order to preferably correspond to each width dimension of each warp sheet S, as shown in FIG. Install it so that it can be moved in any direction. Note that 5 in the figure is a tightening screw for fixing the base 10 of the guide member 1 to the holder.

The inclination angle of the guide member 1, ie, the angle θ at which it intersects with the warp sheet S, is preferably within the range of 15 to 75 degrees, and experiments have shown that the most preferred setting is about 45 degrees. In addition, over 75 degrees (90
It was found that if the threads were to overlap (up to a degree), the threads would overlap, which was undesirable.

The inclination angle θ of this guide member 1 is determined by the warp sheet S
Since the difference will depend on the running speed of the vehicle, it is necessary to design the inclination angle so that it can be changed freely.
Alternatively, it is necessary to prepare multiple pieces having different inclination angles.

In the above embodiment, the guide member 1 is rod-shaped, but it is needless to say that the guide member 1 is not limited to this and may be plate-shaped.

Furthermore, although the above device has been explained as being provided in a pair on the left and right sides of the warp sheet, if multiple pairs are provided,
The effect increases accordingly.

<<Effect of the invention>> As described above, according to this invention, it is possible to prevent the yarn pitches near both ends of the warp sheet S from spreading in the width direction, so that the spread yarns are dried while being entangled in the drying process, and are not used in the next process. Yarn breakage and fuzzing can be prevented during the barrel dividing process. In addition, as the yarns at both ends of the warp sheet S spread in the width direction of the sheet, the spread yarns elongate, which prevents the winding tension from becoming too loose during winding and prevents warp preparation. Therefore, it is possible to improve the quality of the fabric.
