It please refers to shown in Fig. 7 C, two sewing cloths 51 is mutually coincided, and by two sewing cloths 51 along sewing path D1
The accommodating space 14 for moving into sewing machine body 10, in this embodiment, the right side edge of two sewing cloths 51 is set as one can quilt
The suture block 511 that bound edge material 50 covers, as shown, when the suture block 511 of two sewing cloths 51 is close to curler
When 30 opening 311, interior presser feet 421 is close to each other by upper axis and lower axle respectively with feeding tooth 41 so that interior presser feet 421 with
The common clamping bound edge material 50 of feeding tooth 41 and two sewing cloths 51, and then interior presser feet 421 is made to drive two jointly with feeding tooth 41
Sewing cloth 51 is moved along sewing path D1, while interior presser feet 421 and feeding tooth 41 drive bound edge material 50 first jointly
Moved along pan feeding path D2, after again by guidance part 31 along discharging path D3 moved, cause two sewing cloths
The lower sections that material 51 first passes through the first eedle 22, after using the second eedle 23 lower section, and allow two sewing cloths 51 far from seam
The thread direction of operators is removed in accommodating space 14, while bound edge material 50 is merely through the lower section of the second eedle 23, and same
It is removed with the direction far from sewing operators in accommodating space 14, wherein wrapped when interior presser feet 421 drives jointly with feeding tooth 41
When sapwood material 50 and two sewing cloths 51 are moved, guidance part 31 can also synchronize with feeding tooth 41 carried out with interior presser feet 421 it is past
It is multiple mobile.
When interior presser feet 421 is with the common clamping bound edge material 50 of feeding tooth 41 and two sewing cloths 51, the first eedle 22 and
Second eedle 23 is carried a suture secretly simultaneously respectively and is moved down, so that the first eedle 22, which passes through, sutures block 511, and the second machine
Needle 23 passes through bound edge material 50 and suture block 511, then, interior presser feet 421 is cooperated to drive bound edge simultaneously jointly with feeding tooth 41
Material 50 it is synchronous with two sewing cloths 51 respectively along discharging path D3 and sewing path D1 is moved, allow the first eedle 22 into
It is about to the two mutually fixed sewing operations of suture of sewing cloth 51, and the second eedle 23 is carried out 50 liang of sewings of bound edge material simultaneously
The bound edge operation of suture block 511 is fixed in the edge suture of cloth 51, in this embodiment, bound edge material 50 and two sewing cloths
When material 51 is moved respectively along discharging path D3 and sewing path D1 simultaneously, the first eedle 22 also can be same with the second eedle 23
Step is moved back and forth along Y-axis.
When completing sewing operation, the surface of sewing cloth 51 forms a first stitching L1 for being located at suture block 511, and
And when completion packet is changed into industry, bound edge material 50 is covered in suture block 511, and then makes in the first stitching L1, and bound edge material
50 surface forms a second stitching L2 being located on the right side of the first stitching L1, in this embodiment, when completion sewing operation and packet
When each needle mesh of side operation, the first eedle 22 and the second eedle 23 can be away from needle plate 43, at this point, interior presser feet 421 can be separate
Feeding tooth 41 is without pushing down bound edge material 50 and sewing cloth 51, and outer presser feet 422 can allow outer presser feet close to needle plate 43
422 are clamped on two sewing cloths 51 and bound edge material with needle plate 43 jointly, mobile wrong to avoid sewing cloth 51 and bound edge material
Position.
However, the right side that the second stitching L2 is located at the first stitching L1 only facilitates purposes of discussion, that is, such as Fig. 8 A and Fig. 8 B institute
Show, by 22 tandem of the first eedle in the second eedle 23, so that the first eedle 22 and the arrangement of the second eedle 23 are formed and put down
Row is folded the second stitching L2 in the first stitching L1 in the straight line pattern of sewing path D1, or as shown in Fig. 8 C and Fig. 8 D,
By the first eedle 22 close to the pillar 12 of sewing machine body 10, and the second eedle 23 is away from the pillar of sewing machine body 10
12, so that the first eedle 22 and the arrangement of the second eedle 23 form deviation and favour sewing path D1, and then allow the second stitching L2
In the left side of the first stitching L1.
Above explanation and examples are merely exemplary, does not constitute any restrictions to the scope of the utility model.This
Field technical staff should be understood that can be to the utility model technology under the spirit and scope without departing from the utility model
The details and form of scheme are modified or are replaced, but these modifications and replacement are each fallen in the protection scope of the utility model.
