If the sewing cartridge 5 is removed from the swing arm 40 in a state where the opening / closing lid 87 is located at a position other than the closed position, first, the lock member 110 is switched to the locked position without locking the opening / closing lid 87. Is the engaging portion 110c of the lock member 110.
Is formed at the left end portion thereof with a downwardly tapered portion.
Is rotated to the closed position. At this time, the engaged piece 87d temporarily pushes the lock member 110 to the unlocked position side via the tapered portion to enable switching to the closed position.

Next, the sewing operation of the sewing apparatus 1 and the stitches formed on the cloth 70 by the sewing operation will be described with reference to FIG.
7 to 32 and FIGS. 33 and 34.

With the embroidery frame 4 with the cloth 70 attached to the sewing apparatus main body 1 and the sewing cartridge 5, the cartridge driving mechanism 12 swings the sewing cartridge 5 up and down. At this time, the hollow needle 81, the needle cover 83 (when the needle cover 83 is not in contact with the cloth 70), the thread spool 82, the anti-spin mechanism 91 and the like move up and down integrally with the housing case 86. The opening and closing cover 87 is supported by the pin 19a with respect to the sewing apparatus main body 2, and the backflow prevention mechanism 92 provided therein hardly moves up and down.

When sewing is carried out for the first time after the sewing cartridge 5 is mounted on the swing arm 40, as shown in FIG. 27, the sewing is performed in a state where the thread T is fed out from the lower end of the hollow needle 81 to a certain length. When the storage case 86 is lowered from this state, as shown in FIG. 28, first, the needle cover 83 as the presser foot presses the cloth 70 and presses the upper thread T on the cloth 70. The needle cover 83 stops substantially when the cloth 70 is pressed,
Subsequently, the hollow needle 81 descends with respect to the needle cover 83 and pierces the cloth 70. The moment when the hollow needle 81 pierces the cloth 70 is substantially perpendicular to the cloth 70, and the most distal end of the hollow needle 81 is located at the end of the hollow needle 81 on the swing center side of the swing arm 40. Prevent displacement.

The hollow needle 81 pierces the elastic film body 73,
When the thread T extending from the hollow needle 81 contacts the cloth 70, the cloth 7
The thread T at the portion penetrating through the cloth 70 is held by the thread holding force of the elastic film 73, particularly the elasticity of the elastic film body 73. In this state,
When the hollow needle 81 (the thread spool 82 and the spinning prevention mechanism 91) further descends, the thread T is pulled out from the thread spool 82 against the yarn pull-out resistance by the spinning prevention mechanism 91 and the backflow prevention mechanism 92,
A free loop 75 is formed below the cloth 70. At this stage, about half the thread T of the free loop 75 is inside the hollow needle 81.

While the hollow needle 81 pierces the cloth 70 and descends to the lower limit position, the thread T previously fed from the hollow needle 81 is pulled below the cloth 70 and the thread T is pulled out from the thread spool 82 side. A free loop 75 is formed below the cloth 70. Even before the descending hollow needle 81 pierces the cloth 70, the thread T extending from the hollow needle 81 remains in the needle cover 8.
After being pressed by the cloth 70 in Step 3, the thread T that has been fed in advance is restrained from being pulled to the lower side of the cloth 70 to some extent.

Next, when the storage case 86 is lifted, FIG.
As shown in FIG. 9, the hollow needle 81 rises from the lower limit position, the tip of the hollow needle 81 comes off from the cloth 70, and then the cloth presser by the needle cover 83 is released and moves up to the upper limit position together with the hollow needle 81. The hollow needle 81 rises so as to pass through the thread T in a fixed state connecting the backflow prevention mechanism 92 stopped at a certain position and the cloth 70, and the free loop 75 formed below the cloth 70 is held. All of them are exposed to the outside in the state. On the other hand, when the hollow needle 81 moves to the upper limit position,
2 and the anti-spin mechanism 91 also move to the upper limit position. At this time, however, there is no drawing out of the thread T from the back-flow preventing mechanism 92 to the hollow needle 81 side. Since the resistance is applied, the thread
The thread T between the backflow prevention mechanism 92 and the backflow prevention mechanism 92 becomes slack.

Thereafter, as shown in FIG. 30, when the cloth 70 moves in the horizontal direction, the thread T extending from the hollow needle 81 is
Since the thread T is held at 0, the thread T is pulled by the thread holding force, and the slack thread T between the thread spool 82 and the backflow prevention mechanism 92 is pulled out via the backflow prevention mechanism 92. At this time, the yarn holding force of the cloth 70 is much larger than the yarn pull-out resistance of the backflow prevention mechanism 92 alone, so that the free loop 75
There is no danger that the thread T of the above will be pulled toward the hollow needle 81 and come off.

After the cloth 70 moves in the horizontal direction, the storage case 86 is lowered, and the needle cover 83 presses the cloth 70 and the hollow needle 81 pierces the cloth 70 as shown in FIG. When the hollow needle 81 descends from the upper limit position to the lower limit position,
When the slacked remaining thread T is pulled out between the backflow prevention mechanism 92 and the backflow prevention mechanism 92, the thread spool 82 subsequently rotates and the thread T is paid out. The yarn T has an idling prevention mechanism 91 and a backflow prevention mechanism 92.
The yarn pull-out resistance acts, but the anti-spin mechanism 91
Since the yarn pull-out resistance of the backflow prevention mechanism 92 is smaller than the yarn holding force of the cloth 70, the yarn T can be pressed against the cloth 70 by the needle cover 83, so that the free loop 75 formed last time is pulled. The current free loop 75 is formed without falling off the cloth 70.

Next, as shown in FIG. 32, the hollow needle 81 and the needle cover 83 are raised, and thereafter, FIGS. 30 to 32 are repeated. In this manner, the sewing is performed while leaving the thread on the cloth 70 for each sewing processing by the thread holding force due to the elasticity of the cloth 70, and a large number of threads are formed on the back side of the cloth 70 by the upper thread T as shown in FIG. Of the embroidery pattern 76 is formed on the surface of the cloth 70. When a double-sided tape 77 as a fixing material for fixing a large number of free loops 75 is adhered to the back surface of the cloth 70, FIG.
The pattern sewing cloth 78 which is a pattern workpiece shown in FIG.

The double-sided tape 77 allows the free loop 7
Since the thread 5 is not extracted, the embroidery pattern 76 on the surface of the cloth 70 is stabilized without fraying without fixing the thread with another thread or a thread before and after the thread. Then, the pattern sewing cloth 78 can be used as an emblem and adhered and fixed to various objects via the double-sided tape 77. Note that, in addition to the double-sided tape 77, various adhesives or adhesives may be applied in layers on the back surface of the cloth 70 where the free loops 75 remain,
A tape of these various adhesives or adhesives may be formed, and the plurality of free loops 75 may be fixed to the back surface of the cloth 70 with the tape.

Since a large number of the free loops 75 are located on the back side of the cloth 70, the double-sided tape 7
When 7 is attached, irregularities occur on the double-sided tape 77. Therefore, when the cloth 70 is applied as an emblem or the like to the garment via the double-sided tape 77, the garment to be affixed is soft and such an emblem is easily peeled off. Can be improved. Whether the unevenness is formed for each individual free loop or a plurality of free loops depends on the material of the thread or the double-sided tape.
