The invention relates to the technical field of strip steel rolling, in particular to a control method and equipment for stitching centering of thin strip steel in a continuous annealing furnace. The present invention adopts a set of centering devices and a set of side measuring devices before and after the sewing equipment. Whether the running strip and the rear strip are aligned, that is, whether the centerline of the strip is parallel to the centerline of the unit. At the same time, a transverse hydraulic cylinder and a rotary hydraulic cylinder are respectively installed at the front and rear of the sewing equipment. Through the cooperation of the first deviation correction roller and the second deviation correction roller, the front and rear strips of the sewing equipment can be aligned and centered, which can greatly improve the sewing quality. Accuracy, reduce the risk of belt breakage of the unit, and make production run more smoothly. The invention solves the technical problem that the stitching accuracy of the existing control method is poor, especially when the width of the front and rear strips is inconsistent, and there is a risk of strip breakage.

The invention discloses a sewing method for a shoulder joint, which divides the sewing track of the sleeve joint into an upper sewing track and a lower sewing track; wherein, the upper sewing track is set to extend upward and the lower sewing track is set to extend downward; The left and right ends of the upper sewing track have a first extending edge extending toward the sewing edge, the left and right ends of the lower sewing track have a second extending edge extending toward the sewing edge, and the second extending edge is located above the first extending edge, So that: the left and right ends of the upper sewing track and the lower sewing track are correspondingly cross-connected; in this way, it is spliced ​​through two sections of cross-stitch sewing to avoid the entire sleeve and shoulder interface from being completely closed, ensuring the sewing quality of the sleeve and shoulder interface , which improves the simplicity and yield of sewing processing, is more suitable for automatic sewing processing, and has good processing feasibility.

The disposable internal opening cutting and enclosing anastomat is skillful in design, and has a good application prospect; by adopting the disposable internal opening cutting and enclosing anastomat, a plurality of use problems in the prior art can be solved effectively.

The invention relates to an automatic bag patching machine, comprising a station switching mechanism, which includes a driving component and a first bearing component; In the circumferential direction, a folding station, a suspended station, a blanking station and an upload station are arranged in sequence. The transfer component is set on the suspended station, and the upload station is provided with an upload component; The bag patching station is provided with a bag patching component, and the output station is provided with an output component; the uploading station is located just above the bag patching station; the invention solves the problem that the bag patching process of the automatic bag patching machine is controlled After the system is programmed, various operations are automatically completed. Since it is automatic, if the program is wrong, the feeding board will hit other equipment during the movement, resulting in technical problems of mechanical damage.

The invention discloses a mold for sewing a back waist band, and relates to the technical field of sewing machines. The mold comprises a first guiding piece and a second guiding piece, the first guiding piece comprises a base plate, a semi-U-type hook with a rightward opening is arranged on the left side of the base plate, the second guiding piece comprises a support, the upper face of the support is provided with an upper U-type hook with a leftward opening, the lower face of the support is provided with a lower U-type hook with a leftward opening, and a lower half U-type hook body of the lower U-type hook is fixed on the base plate. The mold is simple in structure and low in manufacturing cost, the steps of ironing, seam reversing, seam allowance and the like are omitted, an open thread is directly sewed, the sewing quality can be guaranteed, the sewing speed is greatly quickened, and the work efficiency is greatly improved.

The invention discloses a clothing manufacturing template machine which comprises a template machine base. A working table is fixed to the outer surface of the top end of the template machine base through bolts. Guide grooves are formed in the positions, close to the two sides, of the outer surface of the top end of the working table respectively. A movable plate is movably installed on the innersurface of each guide groove. A control box is fixed to the position, close to the center, of the outer surface of the top end of the working table through bolts. By means of the clothing manufacturing template machine, tools can be more conveniently stored; meanwhile, a placement box can be stored, and the space is prevented from being occupied; the placement box can be more freely and rapidly moved, the activity range of workers is enlarged, the clothing manufacturing template machine can be more conveniently used by workers, and work efficiency is improved; a template shell can be better fixed, it is avoided that the template shell and inner clothing slide relatively during sewing, the sewing precision is better improved, and better use prospects are achieved.

The invention relates to a collar pressing die, collar sewing equipment and a collar sewing method. The collar pressing die comprises a base, a first outer side pressing piece, a second outer side pressing piece and a middle pressing piece. The first outer side pressing piece, the second outer side pressing piece and the middle pressing piece are all movably connected to the base, and the first outer side pressing piece and the second outer side pressing piece are located on the two sides of the middle pressing piece correspondingly.
