At 19a, sweat removal 86 enters the gaps 41a, 48a, 49a so that the embroidery area of the front portion 84 is positioned at the window hole 7. The depth of the covering is determined by visually observing the relative positional relationship of the back surface 85a 'of the base portion 85a of the eave 85 to the two position confirmation members 48 and 49, as shown in FIGS. Former 85
The process is performed until the back surface 85a 'of a is brought into contact with the receiving portions 50 of the left and right position confirmation members 48 and 49. By performing the covering in this manner, the hat C is directly covered at a predetermined position with respect to the hat frame A.

Next, the holding member 25 is put on the front portion 84 of the hat, and the fastening member 32 is hooked on the fastening member 21 and tightened, as is generally known. In this case, as shown in FIG. 11, the contact portion 28a of the member 28 of the presser 25 is the surface at the base 85a of the eave 85.

Next, as shown in FIG. 10, the string-shaped body 53 is hung on the eave 85, and it is laid in a retracted state.
This completes the mounting of the hat C on the hat frame A. Next, the hat frame A in which the hat has been mounted is removed from the holder B. To remove the cap frame A, the cap frame A may be separated from the holder B so that the abutting member 15 comes out from between the receiving member 62 and the fitting body 71. Then, the hat frame A is connected to the drive unit of the embroidery sewing machine and attached to the embroidery sewing machine as is well known.
In this case, the proper attachment state of the hat C can be reconfirmed by visually checking the relationship between the back surface 85a 'of the eave 85 and the position confirmation members 48 and 49.
After mounting, embroidery is performed on the embroidery area of the front portion 84 as is well known. In the case of the embroidery, since the base portion 85a is sandwiched between the abutting portion 28a and the receiving portion 50 as described above, the base portion 85a serves as an anchor, and the integrity of the hat with respect to the hat frame is kept extremely high. Even if the front part 84 is thick, which gives a large resistance as in the case of the needle, the embroidery can be performed accurately by preventing the embroidery area from being displaced with respect to the window hole 7.

Next, when it is not required to sandwich the base portion 85a of the eave 85, as in the case where it is expected that the possibility of occurrence of the above-mentioned misalignment does not occur or is very small during the embroidering, The position confirmation members 48 and 49 may be configured to visually confirm the distance from the back surface 85a 'of the eaves. In this case, the receiving portions 48a and 49a in the above description are replaced with a position checking portion, and the cap is covered with the same distance between the back surface 85a 'of the eave 85 and the left and right position checking portions 48a and 49a. Do what you do to depth.

Next, FIGS. 11 and 12 show different examples of the structure of the cap frame holding member. In the figure, the holding member 55e is formed in a semi-cylindrical shape so that a large through hole 59e for inserting a hand is formed.
In order to make the connecting member 61e for connecting the hat frame obliquely upward or obliquely downward, the base member 56e is pivotally attached to the base member 56e using a screw rod 101, and a fixing fastener such as a knob screw 102 is used. Can be fixed at a desired position. Reference numeral 103 denotes an elongated hole for allowing the screw 102 to move. In such a case, the orientation of the holding member 55e is set in accordance with the preference of the worker, and the work of putting on the hat can be performed in a state where the work is easy.

Next, FIG. 14 shows a state in which the position confirmation members 48e and 49e are provided on the hat frame holder, for example, as shown in FIGS.
