る。2. Description of the Related Art When sewing a folded fabric such as the rib knitted fabric described above onto a main sewing material such as a trainer, conventionally, a hitting ruler as shown in FIG. 4 is arranged at a position before the needle drop portion. It was designed to guide the feeding of bifolds. This abutting ruler is attached to the fixed guide 31 having a rising re-guide piece 30 at the free end with which the folded portion of the half-folded fabric abuts, and the fixed guide 31 so as to be opposed to the rising re-guide piece 30 so that the relative spacing can be adjusted. Movable guide piece 32 with which the upper and lower edges of the folded fabric
And a pair of guide pieces 30 and 32 on the left and right,

まねいて、縫製品に多くの不良品を発生するという問題
があった。However, in the case of the conventional cloth edge guide device composed of the ruler having the above-mentioned construction, the edges of the upper and lower sides of the folded state are set at the start of sewing. However, in view of the shapes of the guide pieces 30 and 32, the upper and lower cloth portions are likely to be relatively displaced in the width direction as the sewing progresses. In particular, the shift of the upper part of the folded fabric can be visually recognized by the operator well, but the shift of the lower part is difficult or invisible to the operator, and the sewing is continued without noticing the shift. There is a high possibility that, as a result, the half-folded cloth will not be sewn to the main-sewn fabric in a predetermined manner, leading to a sewing failure such as an unsewn stitch, resulting in many defective sewing products.

ない。In order to eliminate such defective sewing such as miss-sewn, it is possible to reduce the sewing speed and proceed with the sewing while aligning the edges repeatedly.
In this case, not only is the sewing work efficiency inferior, the productivity of the sewn product is extremely reduced, the skill is required for the work, and this is not practical.

の面で好ましくない。Further, prior to the start of sewing, an iron is applied to the folded portion of the half-folded fabric to form an accurate crease in the folded portion, so that both upper and lower fabric portions at the time of sewing are sewn. Although it has been considered to suppress the occurrence of misalignment, in this case, a separate manual process of ironing is required before sewing, which is not preferable in terms of productivity and cost.

させるものである。Further, in order to solve these problems, the present applicant has proposed a cloth edge guide device for a double-fold cloth sewing machine as shown in Japanese Patent Application No. 3-7292. There is. The cloth edge guide device for the sewing machine for bi-fold fabric sewing proposed earlier is generally placed on one side of the front part of the needle drop part and is substantially reversed so as to abut on the folding part of the bi-fold fabric. A first guide member curved in a V shape, and an upper part and a lower part of the bi-folded fabric, which are arranged on the other side of the front part of the needle drop portion facing the opening side of the first guide member. Is disposed between a pair of upper and lower guide portions that are curved in a substantially U-shape so as to be in contact with respective end edges of the second guide member, and these guide portions are arranged between the pair of upper and lower guide portions. And a bending protrusion protruding toward the first guide member,
By moving the folding protrusion and the second guide member closer to the first guide member along a horizontal plane, the cloth set in the approximately two-fold state is pushed by the pushing force of the folding protrusion into a predetermined two-fold shape. While being folded in a fold shape, the edges of the upper and lower both sides of the folded double-folded fabric are brought into contact with the inner surfaces of the bent portions of the pair of upper and lower guide portions of the second guide member to guide the feed.

があった。According to the above-proposed cloth edge guide device, the edges of the upper and lower sides of the folded fabric can be surely aligned and the finished sewing can be performed without lowering the sewing speed. However, in the previous proposal, since the installation location of the first guide member is fixed, there is little room for the operator to set the roughly folded fabric and take it out after sewing. There was room for improvement in that it was difficult to do the setting and removing work.
