In the conventional cap frame described above, it is necessary to hold the base frame with one hand, cover the cap with the other hand, apply a tension spring, and fix the cap frame. Therefore, there are problems that it is very difficult to work and that it takes a long time. Further, when the above-mentioned hat frame is used for a multi-head sewing machine, for example, a 20-head sewing machine, the number of hat frames is 40 during the embroidery work and when the cap is attached in advance to prepare for the embroidery work. However, there is a problem that the cost for the tension spring is very high because all of them have a tension spring, and any cap frame is bulky due to the existence of the tension spring. However, there was a problem that a large space was required to accommodate it.

The present invention has been made in order to solve the above-mentioned problems (technical problems) of the prior art, and the work of attaching the hat to the hat frame can be carried out very easily and quickly, and many When using the cap frame of No. 1, the cost for the tension spring in the cap frame is significantly reduced by enabling the cap to be in a tensioned state even if the cap frame does not have a tension spring. It is an object of the present invention to provide a hat frame holder capable of reducing the space for housing the frame.

[0006]

In order to achieve the above object, the cap frame holder according to the present invention is a space for laterally positioning the cap frame with the embroidering window hole in the cap frame facing upward. The holding member for a hat frame provided with is provided with a base member for making the holding member self-supporting in a part thereof, and further for connecting the connecting portion of the hat frame base portion to the side surface of the holding member in a detachable manner. When a part of the peripheral wall of the hat is covered on the connecting member and the window hole, a tension spring for pulling the peripheral wall of the part to the window hole is provided.
