摘要

A curved cloth stretch frame device for an embroidery sewing machine comprises a substantially cylindrical frame body with an embroidery window, a reciprocation transmission to transfer the frame body axially and a rotation transmission to rotate the frame body. A curved cloth workpiece, such as the arm of a shirt, is put into the frame tightly. The frame is driven axially and in rotation and a wide curved area of the workpiece can be embroidered continuously.
