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.

It is configured such that the position can be adjusted in the left-right, up-down, and front-rear directions via mounting plates 33, 34, 35 having a and screws 36, respectively. Predetermined sewing is performed while aligning the edges of both the upper and lower sides of the folded fabric by bringing the folded portion and the edges of the upper and lower sides of the folded fabric into contact with each other and transporting them toward the needle drop portion. It is a thing.

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.

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. Furthermore, prior to the start of sewing, the folded portion of the bi-folded fabric is ironed and an accurate crease is formed in the folded portion, so that the upper and lower fabric portions are not misaligned during sewing. Although it is also considered to suppress the generation, in this case, a separate step of manual work such as ironing is required, which is not preferable in terms of productivity and cost.

According to the first aspect of the present invention, the second guide and the bending protrusion are separated from the first guide, and the first guide is manually folded into about two folds.
After being set on the guide side, the drive mechanism is operated to integrally move the second guide and the bending projection piece along the horizontal plane to the first guide side. This movement consists of a forward movement in which the tip of the above-mentioned bending projection enters into the inside of the bent portion of the first guide, and immediately after that, a backward movement over a distance corresponding to approximately half the total width of the fabric. With the forward movement, the cloth set in the above-described two-fold structure is folded into a predetermined two-fold shape by the pushing force of the folding projection piece, and the folded half-folded cloth is On the inner surface of the bent portion of the first guide where the bent portion is curved in an almost inverted shape,
Further, the edges of the upper and lower side portions are respectively brought into contact with the inner surfaces of the bent portions of the pair of upper and lower guide portions in the second guide which is curved in a substantially U shape. After that, the main sewing material is overlaid on the half-folded fabric and the predetermined sewing is performed while feeding the both in the same direction. The state where the first guide and the second guide are in contact with the upper and lower guide portions is surely maintained, and the upper and lower both side portions of the half-folded cloth are displaced relative to each other in the width direction during sewing, resulting in disengagement of the sewing. It is possible to prevent the occurrence of poor sewing such as.

Next, the operation of the above configuration will be described. First, the air cylinder 16 is contracted so that the second guide 11 and the bending projection 12 are separated from the first guide 10 as shown in FIG. Is folded in half manually and set on the first guide 10 side. In this state, the air cylinder 16 is extended to move the second guide 11 and the bending projection 12 toward the first guide 10 side along the horizontal plane. Here, this movement is, as shown in FIG. 3B, a forward movement in which the tip of the bending projection 12 enters into the inside of the bent portion of the first guide 10 and immediately after that, a forward movement. As shown in (c), the second guide 11 comprises a backward movement so as to stop at a position corresponding to almost half of the entire width of the fabric A, and the second guide 11 is roughly folded in two with the forward movement. The fabric A set at is folded into a predetermined two-fold shape by the pushing force of the folding projection 12, and the folded-fold fabric A is folded as described above at a position stopped by the backward movement. The outer surface of the portion A1 is brought into contact with the inner surface of the bent portion of the first guide 10, and the respective end edges of the upper and lower side portions A2 and A3 thereof are paired with the upper and lower guide portions 11 of the second guide 11.
A. The inner surfaces of the bent portions of 11B are brought into contact with each other to establish a predetermined cloth edge guiding action.

Then, the sewing operation by the sewing machine is started in a state where the end portion of the main sewing material B set so as to be transferred and guided by the roller group 21 is overlapped on the folded fabric A. Predetermined sewing is performed by sewing the vicinity of both end edges of the half-folded fabric A to the main sewing fabric B. At this time, the folded portion A1 of the half-folded fabric A and the respective end edges of the upper and lower side portions A2, A3 are respectively Upper and lower guide portions 11 of the first guide 10 and the second guide 11
The contact state of the A and 11B with the inner surface of the bent portion is maintained, and therefore, the upper and lower side portions A2 and A3 of the half-folded fabric A are relatively displaced in the width direction during sewing. The main sewing material B can be sewn on the main sewing material B with the edges thereof aligned.

As described above, according to the first aspect of the present invention, the folded portion and the edges of the upper and lower side portions of the bi-fold fabric to be sewn are curved in an inverted V shape and an inverted V shape. Since it is configured to contact the inner surfaces of the bent portions of the first and second guides respectively for guiding the transfer, it is possible to prevent the cloth portions on the upper and lower sides from being relatively displaced in the width direction while sewing. That is, the upper and lower edges can be reliably aligned, and the main sewing material can be sewn reliably and satisfactorily without causing sewing defects such as disengagement. Moreover, in order to align the edges, it is not necessary to manually perform another process such as ironing, or to reduce the sewing speed, and labor-saving sewn products with good finish can be made.
In addition, there is an effect that it can be obtained with high productivity.

According to the second aspect of the present invention, during the sewing operation of the above-mentioned folded fabric, the feeding direction of the folded fabric can be properly adjusted according to the characteristics of the fabric. Therefore, regardless of the characteristics of the cloth, it is possible to surely exhibit the function of preventing the misalignment of the upper and lower sides of the folded cloth.
