た。 For this type of tension frame, the fabric is layered on a ring-shaped tension frame, a circular core with a slightly smaller diameter is placed on top of the fabric, and the fabric is sandwiched between the inner surface of the tension frame and the outer surface of the core. The cloth was being pulled. Thereafter, by connecting a connecting portion provided on a part of the tension frame to a drive attachment, the tension frame is moved back and forth and left and right on a plane to embroider the cloth surface. However, the above-mentioned tension frame cannot be used if the eaves piece is attached to the above-mentioned hat, and in the case of cylindrical sleeves, the tension frame is first inserted into the sleeve, leaving a space for inserting the pot. This had the major disadvantage that only an extremely small tension frame could be accommodated, and in the end, only a small amount of fabric could be embroidered.

そこで本発明は、上述の欠点を除くようにした
