The invention relates to a machine (M) for sewing, embroidering or quilting, comprising: a needle bar which is arranged above a needle plate (SP) and can be moved up and down and to which a needle (N) is fastened; a gripper system which is arranged below the needle plate (SP) and can be moved back and forth and to which a gripper is fastened; a presser foot (NF) which is arranged above the needle plate (SP) and by means of which a portion of a textile structure can be pressed against the needle plate (SP), wherein the needle plate (SP) has at least one opening or hole (A0) for the passing of the needle (N) through the needle plate (SP) downward and back, and wherein the needle plate (SP) can be stationarily mounted on a needle plate receiving region (AB) of the machine (M). According to the invention, a) at least one sub-region (TSP) of the needle plate (SP) is magnetic and one sub-region (TAB) of the needle plate receiving region (AB) corresponding to the sub-region (TSP) of the needle plate (SP) is magnetic or magnetizable; and / or b) at least one sub-region (TAB) of the needle plate receiving region (AB) is magnetic and one sub-region (TSP) of the needle plate (SP) corresponding to the sub-region (TAB) of the needle plate receiving region (AB) is magnetic or magnetizable.

This invention belongs to the field of down jacket anti-feather leakage technology, and discloses a device for reinforcing and securing the seams of down jackets to prevent feather leakage. The device includes a work platform with a sewing machine head installed in the center. A needle is installed at the end of the sewing machine head. Through the coordination of structures such as a down-pressing plate, a fabric-pressing plate, a pusher block, and a needle plate, the device facilitates precise positioning and sewing of the filled down jacket fabric. During positioning, the sewn edges of the fabric are aligned with the pusher block. Then, the down-pressing plate is inserted between the two layers of fabric to press in the down filling. The upper fabric is held by the fabric-pressing plate, and the lower fabric is pressed against the base plate by a clamping plate. Both ends are pressed tightly by the needle plate to prevent displacement. The pusher block is pushed at a uniform speed according to the sewing speed. At this time, the entire fabric moves forward with the base plate, and the down filling is continuously and evenly pressed inward by the down-pressing plate, facilitating overlock sewing and ensuring no down is trapped at the seam, thus reinforcing the seams.

The utility model discloses a kind of pinhole plate and template machine, pinhole plate includes pinhole plate body, first boss, first through hole and pad high block, pinhole plate body is used to connect with the needle plate of template machine;First boss is protruded to the side of first plate body away from needle plate along first direction, first boss is used to support cloth located in the side of first boss away from pinhole plate body;First through hole is through pinhole plate body and first boss along first direction, first through hole is used to be provided with the needle of template machine, to carry out sewing to the sewing position to be located in first through hole in cloth;Pad high block is protruded to the side of first boss away from pinhole plate body along first direction, pad high block is used to support cloth after needle sewing, and move to the side of pad high block away from first boss;Wherein, when a previous sewing position to be moved to the side of pad high block away from first boss after needle sewing, a subsequent sewing position is moved into first through hole;The flatness of cloth is improved.

The utility model provides a needle plate and sewing machine thereof belong to sewing machine part technical field, a needle plate, include: board body, the board body has needle hole, the needle hole is used for the needle passes through, the board body has at least one through groove, the through groove is used for the movement of the feeding tooth, be provided with passageway on the board body, the outlet of passageway is aligned with needle hole, and the passageway is used for transmission for banded material, the utility model has the advantage that the sewing effect is better.

To make the finish of a cutting part favorable.SOLUTION: In a needle plate 40, a needle plate hole 44 is constituted by including a hole side cutting side 44A for cutting a cutting object 50 together with a blade part 34, and an escape side 44B for allowing a cutting part 52 of the cutting object 50 to escape. Specifically, the needle plate hole 44 has the hole side cutting side 44A for shearing the cutting object 50 together with a blade side cutting side 34A of a blade part 34, and the escape side 44B for forming a gap G1 between itself and the blade part 34 to be inserted. Thereby, the cutting object 50 can be cut by the hole side cutting side 44A and the blade side cutting side 34A in the early stage of the cutting processing. Also, in the later stage of the cutting processing, the cutting part 52 to be inserted in the needle plate hole 44 by the blade part 34 is allowed to escape to the escape side 44B side, and the blade part 34 and the cutting part 52 can be arranged in the needle plate hole 44. Thus, the finish of the cutting part 52 of the cut object 50 can be made favorable.SELECTED DRAWING: Figure 3
