At this time, the upper and lower peripheral portions 70a, 70b in the height direction of the hat of the embroidery area 69 are substantially equal because, for example, the pressing band 3 does not correspond to the rising amount of the sewing portion 77 from the upper surface of the receiving frame 2. If it cannot be held down with a sufficient strength, the hook 38 is removed from the hook 14 and the wing nut 49 is loosened. Then, the relative length between the second band piece 32 on the top of the head and the first band piece 31 on the eaves side is adjusted, and the hook 38 is connected to the hook 14 again. By appropriately repeating this, the pressing band 3 is adjusted so as to press the upper and lower peripheral portions 70a and 70b in the hat height direction of the embroidery range 69 with substantially uniform strength.
Similarly, when the pressing band 3 does not correspond to the size of the embroidery area 69, the second band piece 32
The relative spacing between the first band piece 31 and the first band piece 31 is adjusted.

In this state, as shown in FIGS. 7 and 8, in addition to the seam allowance of the cap portion 62, the seam allowance of the mesh portion 63, and the seam allowance of the sweat stop portion 64, the sweat stop portion 64 and the mesh portion 63 also have the first window. It fits inside the part 24. For this reason, the floating of the embroidery area 69 from the receiving frame 2 on the side of the eaves portion can be reduced as compared with the related art.

The pressing band 3 presses the peripheral portion 70 and the eave portions 6 by the connecting portions 36 and 37.
6 so as to press the cap portion 62 in the vicinity of the base side of the both sides so that the both sides approach each other. At this time, since the small opening 25b is provided on the upper surface of the receiving frame 2 corresponding to the position pressed by the connecting portions 36 and 37, the eaves 66 are provided in the small opening 25b.
Can be pushed into the vicinity of the root side of both sides and the cap portion 62 in the vicinity thereof, and the both sides of the eaves 66 can be pressed closer to each other. In this manner, when the both sides of the cap of the eaves portion 66 are pressed in a direction approaching each other, the eaves portion 66 is bent in an arc shape as shown by a two-dot chain line in FIG. 11 and inclined in a direction away from the embroidery area 69. Therefore, as shown in FIGS. 6 to 8, the hat 61 is held by the hat frame 1 in a state of being inclined in a direction away from the embroidery area 69.

According to the hat frame 1 for an embroidery sewing machine of the present invention configured as described above, the pressing band 3 is
, And the cap portion 62 near the root of the both sides and the cap portion 62 near the both sides so that both sides of the eaves portion 66 approach each other. For this reason,
When the holding band 3 is attached to the receiving frame 2, the eaves 6
6 are bent in an arc shape and inclined in a direction away from the embroidery area 69. Therefore, unlike the related art, there is no need to forcibly tilt the eaves. Therefore, a device for forcibly tilting the eaves portion 66 becomes unnecessary. Further, the operation of forcibly tilting the eave portion 66 can be omitted. Since this operation can be omitted, the mounting position of the hat 61 with respect to the hat frame is not shifted during the operation, and it is not necessary to re-attach the hat 61 at all.

Further, since the pressing band 3 is provided with the first positioning pieces for positioning the cap portions near the roots on both sides of the eaves portion 66, the connecting portions 36 and 37 as the pressing portions of the pressing band 3 are formed. The vicinity of the base side of both sides of the eave portion 66 and the cap portion 62 in the vicinity can be reliably pressed.

The receiving frame 2 is provided with a small opening 25 on the upper surface at a position corresponding to the base on both sides of the eaves 66.
b, the eaves 6 are provided in the small opening 25b.
6 can be pushed into the vicinity of the base side of both sides and the cap portion 62 in the vicinity thereof, and the both sides of the eaves 66 can be pressed so as to be closer to each other. Therefore, the inclination of the eaves 66 in a direction away from the embroidery area can be increased.

Further, since the receiving frame 2 is configured such that the size of the small opening 25b is adjustable, the size of the small opening 2b can be adjusted according to the structure of the hat 61 and the type and thickness of the cloth of the hat 61.
5b can be set to an appropriate size.

It should be noted that the present invention is not limited to the above-described embodiment, and can be embodied by appropriately changing the scope of the invention as follows, for example, as follows. (1) A recess is provided on the upper surface of the receiving frame 2 instead of the small opening 25b. Further, the size (width) of the recess is adjustable. (2) The holding band 3 hat is configured so as to hold the tip side rather than the root side of the eaves on both sides of the eaves.
