Abstract: To improve embroidery precision by preventing the front end of an embroidery frame from being pulled down by the weight of cloth workpiece, the embroidery sewing machine comprises: at least one cylindrical bed disposed on the upper portion of a machine frame; a table disposed on the upper portion of the machine frame and divided into a fixed table and an up-and-down table; a mechanism for supporting the up-and-down table vertically movably at an upward position roughly flush with the cylindrical bed and at least two downward positions of different height; and a mechanism for holding the up-and-down table at the upward position and the at least two downward positions, respectively.

Abstract: An embroidery frame mounting device is provided for an embroidering machine. The mounting device comprises: a rear mounting member for mounting the rear portion of an embroidery frame on a frame, which is disposed on a table of the embroidering machine; and a front mounting member for mounting the front portion of the embroidery frame on the same frame. The rear mounting member is constructed to include a rear bracket mounted on the embroidery frame, a rear positioning unit for positioning the rear bracket transversely with respect to the frame, and a spring for urging and holding the rear bracket on the frame. The front mounting member is constructed to include a front bracket mounted on the embroidery frame, a front positioning unit for positioning the front bracket longitudinally and transversely with respect to the frame, and a magnet for attracting and holding the front bracket on the frame.

Abstract: A cloth spreading frame is joined to a driving frame so that the cloth spreading frame projects horizontally therefrom. This cloth spreading frame is supported at the free end portion thereof on a leg which can be moved horizontally therewith. Accordingly, even when the cloth spreading frame is formed to a large size so that a cloth having a large region to be embroidered can be set thereon, and, moreover, even when the cloth spreading frame is formed with material of a large diameter and a large thickness so that the cloth spreading frame can follow up a movement of a driving frame without being vibrated laterally, the lowering of the free end portion of the cloth spreading frame can be prevented, so that the embroidering of a cloth can be done properly.

Abstract: A fabric holding frame consists of a bed plate and a presser frame connected to the bed plate for vertical movement relative to it. The bed plate is provided with a positioner to locate a fabric and plural windows. The presser frame is provided with strap holders at positions where the strap holders face the respective windows. The fabric is put and located on the bed plate and the presser frame is lowered to fix the fabric. The both end portions of plural straps are loaded into the respective plural strap holders. Thus the both end portions of every strap become located at prescribed sewing positions on the fabric. When the bed plate is horizontally moved on a table of a multi-head sewing machine and the sewing machine is operated, the end portions of the straps are sewn on the fabric through the windows of the bed plate.
