Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weft selvage processing method in which the kasuri weft is folded back at the correct turning point and the kasuri weft is accurately expressed in a predetermined manner. To explain with reference to the attached drawings, a glue 4 is applied and fixed on the upper and lower surfaces of the edges of both edges of the weft winding plate 2 on which the weft yarn 1 is wound for Kasuri printing, leaving the end surfaces 3 of both left and right edges. A fixed ear portion a is formed.

Generally speaking, when weaving kasuri fabrics, it is important that the kasuri be matched accurately, but for the kasuri to be accurately matched, the weft threads must be folded back at the correct position.

However, in reality, the pattern may become slightly misaligned due to various causes such as changes in the tension of the thread, expansion and contraction of the thread, and changes in the popping force of the shuttle, and if these factors accumulate, the pattern will become misaligned to the point where it becomes mismatched.

In this regard, in the present invention, adhesive is applied and fixed to the upper and lower surfaces of the edges of both edges, leaving only the end sides of the left and right edges of the weft winding board on which the weft is wound for Kasuri printing, to form fixed edges. Fixed selvages are formed on the left and right sides of the weft winding board, leaving only the thickness of the end side of the weft winding board, and the fixed selvedges hardened with glue are located on the left and right sides of the correct folding point. Even if the folding position is slightly deviated, the fabric will always be folded back at the correct folding position between the easily folded fixed ears located right next to each other, so that the kasuri pattern can be automatically and accurately matched.

Moreover, the formation of the fixed selvage is done by applying glue to the upper and lower surfaces of the selvages on both sides, leaving only the left and right end sides of the weft-wound board around which the weft is wound, and fixing it in place. It exhibits an excellent feature of being able to form a fixed ear part.
