Abstract
A sewing machine serves to form stitches on a curved work fabric by an upper and a lower thread through cooperation of a shuttle and a needle vertically reciprocally driven. The sewing machine includes a holder device for retaining the work fabric to be sewn. The holder device is supported by a support device and is rotatably within a plane in parallel to X axis. The support device is movable in a direction of Y axis. The X axis and the Y axis are perpendicular to each other within a plane extending substantially perpendicular to the driving direction of the needle. The holder device is rotated by an X axis drive mechanism within the plane in parallel to the X axis. The support device is moved by a Y axis drive mechanism in the direction of the Y axis. The holder device serves to retain the work fabric so as to provide a sewable area for substantially the entire circumferential surface of the work fabric.
