ABSTRACT:
A device for sewing tubular material workpieces comprises a sewing machine mounted in a fixed location adjacent a workpiece holder which, for example is shaped to hold a cylindrical workpiece such as a skirt. The holder is engageable in a rotation drive which rotates the holder at a selected speed. A first setting device is connected to the holder so as to move it upwardly and downwardly in respect to the sewing machine. A second setting device is connected to the first setting device and moves it together with the holder toward and away from the sewing machine as desired. The construction includes a pedal control for regulating the speed of rotation of the workpiece and also the operational speed of the sewing machine.
