Abstract (en)
[origin: CA3002269A1] A sewing unit (1) for sewing seams located multidimensionally in space has a sewing head. The latter has a needle bar upper part (12) in which a needle bar (11) is mounted so as to be driven up and down along its longitudinal axis (13). At least one sewing needle (9, 10) is held, as a stitch-forming tool, on the needle bar (11). The needle bar upper part (12) is mounted in a pivotable manner in a sewing head upper part (14) so as to be driven about the needle bar longitudinal axis (13). At least one gripper is mounted, as a stitch-forming tool driven synchronously with the sewing needle (9, 10), on a gripper lower part (17) of the sewing head. The gripper lower part (17) is mounted in a pivotable manner in a sewing head lower part (18) so as to be driven about the needle bar longitudinal axis (13) synchronously with the needle bar upper part (12). Motor components (19, 69) for driving the up and down movement of the needle bar (11), for pivoting the needle bar upper part (12), for driving the gripper synchronously with the needle bar (11) and for pivoting the gripper lower part (17) are arranged outside the needle bar upper part (12) and outside the gripper lower part (17). This results in a sewing unit with which even parts that are to be sewn in a topographically irregular manner are made accessible for sewing.
