Sewing machine head including a rotary housing

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.
