    摘要: At a sewing automat the sewing head is provided with a rotary housing incorporating a needle bar, a needle bar jogging mechanism and a thread take-up mechanism and a rotatable hook bearing receiving a hook, in order to generate a tangentially directed needle feed movement of the needle relative to the seam to be produced. In order to achieve constant lengths of stitches at swivel motions of the rotary housing and the hook bearing a rotary position indicator associated to a central control unit is connected to a main drive shaft, wherein the rotary position indicator puts out a pre-given number of pulses per revolution of a main drive shaft. The main drive shaft and an adjusting shaft are operably connected to the rotary position indicator via a differential gear in such a manner that at swivelling of the adjusting shaft the rotary position indicator generates a number of pulses corresponding to the swivelling of the adjusting shaft.

    摘要: An automatic sewing machine has a guiding device by means of which workpieces can be guided, on the one hand, from a taking over position to a sewing position under a sewing head and, on the other hand, under this sewing head in two coordinate directions. To enable the handling of large workpieces in the case of a particularly simple design, the whole guiding device is arranged above a workpiece receiving plate for the workpieces, a free space for large workpieces being provided on the side of the workpiece receiving plate lying opposite an operator's side.

    摘要: A sewing device with a sewing head and a feeding device for generating a two-axis-relative motion of a constant velocity between a workpiece to be stitched wherein the sewing head has a rotary housing pivoted about an axis of rotation at the sewing head. In the housing, a needle bar including a needle is pivoted and the needle bar essentially extends about the axis of rotation. The housing further has a common drive for a thread take-up means and a crank including a jogging gear, wherein the two latter cooperate to produce a needle feed movement. The rotary housing is rotatably controlled together with a bearing bracket including a hook, in order to render possible sewing of a stitch contour, wherein the needle feed movement is tangentially guided relative to the individual sewing direction.

    摘要: An automatic sewing machine for sewing workpieces of different sizes is described, in which relative movement between a workpiece and the needle of a sewing head is controlled by a computer receiving the program according to the contour to be stitched. A measuring device is provided for automatically matching the relative movement of the sewing process with the size adjustable workpiece receiving elements. The measuring device continuously detects the size adjustment of the workpiece receiving elements and feeds the size adjustment into an adapting electronic unit converting analog information into digital information used by the computer controlling the stitching operation.
