Abstract
A sewing system serves for sewing seams which the multi-dimensionally in space. A needle-bar upper part of a sewing head is mounted so as to be pivotable in a driven manner about a needle-bar longitudinal axis. A gripper lower part is mounted so as to be pivotable in a driven manner, and in a manner synchronous with the needle-bar upper part, about the needle-bar longitudinal axis, in the sewing-head lower part. Motor components for driving the movement of a needle bar, for pivoting the needle-bar upper part, for driving a gripper in a manner synchronous with the needle bar and for pivoting the gripper lower part are disposed outside the needle-bar upper part and outside the gripper lower part. Parts to be sewn that are topographically non-uniform are also rendered accessible.
Claims10
A sewing system for sewing seams which lie multi-dimensionally in space, the sewing system comprising:
- a sewing head comprising a needle-bar upper part, a sewing-head upper part, a gripper lower part and a sewing-head lower part, wherein a needle bar is mounted in the needle-bar upper part so as to be driven in an upward and downward manner along a longitudinal axis of the needle bar, at least one sewing needle being held as a stitch-formation tool on the needle bar, the needle-bar upper part being mounted in the sewing-head upper part so as to be pivotable in a driven manner about the longitudinal axis of the needle bar, at least one gripper being mounted on the gripper lower part as a stitch-formation tool that is driven in a manner synchronous with the at least one sewing needle, the gripper lower part being mounted in the sewing-head lower part so as to be pivotable in a driven manner, and in a manner synchronous with the needle-bar upper part, about the longitudinal axis of the needle bar;
- motor components for driving upward and downward movement of the needle bar, pivoting the needle-bar upper part, driving the at least one gripper in a manner synchronous with the needle bar and pivoting the gripper lower part, the motor components being disposed outside the needle-bar upper part and outside the gripper lower part.
