the workpiece 3 together with the workpiece cut 4 to the intermediate point 164 after termination of the seam 163 and without sewing from the end point 119 of the seam 163 while the workpiece holder 29 together with the workpiece 3 and the workpiece cut 4 moves from the end point 165 to the intermediate point 164 the rotary housing 33 and the hook bearing 63 are returned into a neutral starting position due to the correspondingly profiled groove 57 fig3 the needle feed motion is performed extending in a vertical plane with respect to the plane of the drawing as it is commonly known from sewing machines provided with a feed drive the action of the jogging gear 93 causes a superposition of the oscillatory motion of the needle 35 with a vibratory motion of the needle bar bearing frame 90 so that the not illustrated point of the needle 35 performs a closed elliptical path i e the needle 35 performs the already described needle feed motion the needle 35 receives in its upper respectively lower dead center of the elliptical path a usual vertically directed position which corresponds to the axis 34 the largest angle of deviation of the needle 35 with repsect to the axis 34 measures about 1 u00b0 the feeding device 2 continuously displaces the workpiece holder 29 in such a manner that the workpiece 3 together with the workpiece cut 4 is moved relative to the needle 35 according to the course of the seam.
