【考案の詳細な説明】 この考案はミシンにおける被縫布の位置決め装置に関す
る。[Detailed Description of the Invention] This invention relates to a positioning device for a cloth to be sewn in a sewing machine.

第１図に示すようなポロシャツＰの胸元を形成する上下
前立布１，２はそれらの側縁を相互に正確に位置決めし
た重ね合わせた後に基部を四角形にサイクル縫いＣして
縫い合わされている。As shown in Figure 1, the upper and lower fly fabrics 1 and 2 that form the chest area of a polo shirt P are overlapped with their side edges positioned accurately, and then sewn together by cycle stitching C into a square shape at the base. .

しかしながら、従来は上下前立布１，２の重ね合せの位
置決め及び縫合部への位置決めは作業者の目測により行
っていたので、下前宣布２の側縁が上前宣布１の側縁よ
りづれて重ね合されそのまま縫合されてしまい縫い合せ
部分の下前宣布２が上前宣布１よりはみ出てしまったり
、下前宣布２と上前宣布１をが縫合されない部分が生じ
たりまたサイクル縫目が上前宣布１，２の両側縁から一
定の位置に形成されず商品価値が低下するという欠点が
あった。However, in the past, the overlapping position of the upper and lower front fabrics 1 and 2 and the positioning of the seams were performed by the operator's eye, so the side edge of the lower front fabric 2 was shifted from the side edge of the upper front fabric 1. If they are overlapped and sewn as they are, the lower front declaration 2 of the sewn part will protrude from the upper front declaration 1, or there will be a part where the lower front declaration 2 and the upper front declaration 1 are not sewn together, or if the cycle stitch is on the upper side. There was a drawback that it was not formed at a fixed position from both side edges of the previous proclamations 1 and 2, resulting in a decrease in commercial value.
