The present invention relates to an embroidery and a shuttle for a sewing machine.

In particular, the present invention relates to a shuttle used for an embroidery machine of the type as described in Austrian Patent No. 380,905. In this type of needle embroidery machine, the driving device, part of the embroidery machine, periodically moves the shuttle up and down along the steep slope of the shuttle support. The operation of this embroidery machine is that the needle slot is arranged at the weak point of the track of the shuttle support stand so that the pointed end of the shuttle is located below the needle slot at its associative position, and the pointed end of the shuttle during the ascending stroke is the needle thread. To pass through the loop. In its upper position, the rounded end of the shuttle passes completely through the needle slot, allowing the needle thread to pass over the shuttle in the downstroke and to be pulled during the back stroke of the needle. Of course, the stroke of the needle and the up-and-down movement of the shuttle are completely synchronized so that mutual movement is related. The needle loop is formed at the beginning of the reverse stroke of the needle. Therefore, shuttles move up and down constantly along their course through the loops formed by the needles during the embroidery operation, and when the colors change or the pattern is repeated again and again, the needles are at rest but the shuttle is in the vertical direction. Continues to vibrate. Therefore, the north chamber may be stuck between the active surface and the shuttle's moving path or adhered to the lower side of the cover. This entanglement of the bobbin thread interferes with maintaining the uniformity of the embroidery pattern, and also causes the drum thread to be broken.

Wood of the present invention is to provide a shuttle that can prevent the thread is pinched in this type of embroidery machine.

This object can be achieved according to the present invention in which the slits from which the thread is released instead of the annular opening exit provide a new shuttle formed in the side wall. In the present invention, the slits are configured to be inclined upward toward the rear end of the shuttle.

Referring to the present invention in more detail based on the accompanying drawings as follows.

As can be seen in FIG. 1, the shuttle 1 is located on the shuttle track or track 2 which is schematically shown. The moving path 2 is formed with a needle slot 21 for allowing the needle to be inserted during the embroidery operation. When the shuttle is moved specifically along the path 2 it passes through the loop formed by the needle. While the shuttle moves back down to its initial position, the drum f of constant length is released from the slits 11 and caught. The slits 11 are formed to be long, unlike the circular holes formed in the side of the shuttle. The slits of the present invention, in which the north thread is released, are inclined upward toward the rear side of the shuttle and the shuttle F is slipped from the slits to the rear side by the inertia effect because the shuttle accelerates rapidly during the upward movement. Therefore, the north room can be pulled out of the shuttle's active surface, thereby greatly reducing the risk of the room being jammed.

The slits of the present invention, in which the bobbin thread is released, may have an angle of 5 ° -45 ° with the active surface of the shuttle, but an angle between about 12 ° -45 ° is better. 1 to 3 show each embodiment formed at various angles. In FIG. 1, the slits 11 of the present invention formed on the shuttle 1 have an angle of 12 ° with the shuttle active surface. Shown. In the shuttle of FIG. 2, an embodiment in which the angle of the slits 11 'is 23 ° is shown, and FIG. 3 is an embodiment in which the angle of the slits 11 "is 45 °. As can be seen from the embodiment, the angle of the slits formed in the shuttle may be formed by selecting the angle of right within the scope of the present invention.The lower end of the slanted slits is larger as shown in FIG. It is close to the height of the back side of the parent 2.

The slits according to the present invention may also be slightly curved, as indicated by the dashed lines in FIG. 3, which will further maintain.

As described above, although the present invention has been described in relation to several specific embodiments and various details have been described for the purpose of description, those skilled in the art of the present invention may be added without departing from the basic principles of the present invention. Modifications to the embodiments and changes to other configurations are possible.
