Description of the Related Art Conventionally, for example, in order to form curtain folds with a cloth and sew the cloth with a sewing machine, the cloth is supplied to a winding device for two, three or four windings by hand. If the folds of the folds are narrow, or if the fold width of the folds is narrow, various guides will be arranged in parallel from the cloth edge to be wound. The fabric is folded and rounded and supplied to the sewing device by hand, or when the fabric is short, the entire length is mechanically folded at once and supplied to the sewing device by hand.

However, it cannot be used for wide or long objects, and requires a complicated adjustment manual operation in which a skilled worker monitors and corrects the supply state.

Even when the conditions of the fabric are different or the fold width of the folds is large or small, the fold width of the folds can be set to a desired value without excess or shortage of the folds. An object of the present invention is to make it constant and adapt to the width of the folds of the pleats and the length of the fabric, and to omit a complicated manual adjustment operation of the supply.

【発明の効果】本願発明は、前記の構成を備え作用を生
ずるので、布地等の自動供給と捩り送りとにより布地等
の各種条件の相違と従来の手操作による布地等の供給の
不安定による欠陥を解消して、下記の効果を奏する。Since the present invention has the above-described structure and produces an effect, the automatic supply of the cloth and the like and the twisting feed cause the difference in various conditions of the cloth and the like and the unstable supply of the cloth and the like by the conventional manual operation. The following effects are achieved by eliminating defects.
【００２８】変角体によりひだの折り幅を自動的に可変
とし且つベルトの自動送りによって布地等を徐々に捩り
送るので、ひだの折り幅の変更調節が容易であり、ひだ
の左右のずれがなく均等化し、縫い目の布地からの逸れ
がない精度の高いひだを形成できる。Since the folding width of the pleats is automatically varied by the deformed body and the cloth or the like is gradually twisted by the automatic feeding of the belt, it is easy to change and adjust the folding width of the pleats, and the displacement of the pleats on the left and right is reduced. It is possible to form a high-precision pleat without equalization without deviation from the seam fabric.
【００２９】布地等を自動的に徐々に捩りながら送るの
で、ひだの折り幅の広狭に拘らず正確に折って縫着で
き、送り方向へ長い布地等であっても短かいものと同様
に安定したひだを形成できる。Since the cloth is automatically twisted and fed while being gradually twisted, it can be folded and sewn accurately regardless of the width of the folded folds. Even if the cloth is long in the feeding direction, it is as stable as a short cloth. Can form folded folds.
【００３０】上送り体とガイド体，押圧体とが布地等を
ベルトに弾圧しているので、布地等の左右のいずれかに
他の布地を重ねて縫着したり挿入し、または継ぎ合せ目
があって、左右の厚さが相違していても、支障なく搬送
できる。Since the upper feed body, the guide body, and the pressing body press the cloth or the like against the belt, another cloth is sewn or inserted on one of the right and left sides of the cloth or the like, or the seam is inserted. Therefore, even if the left and right thicknesses are different, they can be transported without any trouble.
【００３１】布地のひだ基部のミシンによる縫着時に
は、ひだの左右布地間にスペーサー５１を介在させたの

に起こる縫いしわの欠陥を解消できる。Since the spacer 51 is interposed between the left and right fabrics of the fold at the time of sewing the fold base of the fabric with the sewing machine, there is a margin for the tightening tension of the sewing stitches, and the defect of the wrinkle generated on the fabric can be eliminated. .
