An apparatus and method for applying stitches to a decorative component having a three dimensional configuration is provided. A head for applying stitches to a decorative component having a three dimensional configuration, including: a needle bar assembly operatively coupled to the head; a looper configured to cooperate with the needle bar assembly in order to prove a plurality of stitches in the decorative component, the looper rotating in a plane parallel to the decorative component; a post assembly configured to drive the looper in a reciprocating fashion in the plane, wherein the post assembly is operatively coupled to a motor configured to drive the needle bar assembly in a reciprocating fashion, the post assembly being operatively coupled to the head via a cylinder arm assembly and a downshaft assembly; and wherein the cylinder arm assembly is rotated in a synchronized manner with a rock frame through mechanical linkage connecting a rock frame drive shaft to the cylinder arm assembly.

This single chain stitch sewing device is provided with a sewing mechanism provided on a front end arm of a delivery robot. The sewing mechanism comprises a sewing motor for supplying power to sewing needles and loopers. When the sewing motor is energized, power is transmitted to the sewing needles via a first power transmission mechanism, this causing the sewing needles to move reciprocally. At the same time, power is transmitted to the loopers via a second power transmission mechanism to rotate the loopers. Accordingly, sewing is performed. The loopers are provided at an end of a post bed on the side closer to the sewing needles.

In a first step, a needle pierces into an object to be sewed by reciprocal motion and leaves from the object to be sewed after the tip of the needle has penetrated therethrough. At this time, the needle is placed in a state of being stopped relative to the object to be sewed. In a second step, the needle leaves from the object to be sewed. At this time, the needle is moved relative to the object to be sewed along a sewing direction (sewing line).

A sewing machine frame includes a pillar frame and an extending frame. The extending frame extends from one end in a longitudinal direction of the pillar frame, in an extending direction orthogonal to the longitudinal direction. The extending frame includes a first extending plate, a second extending plate, and an extending intermediate plate. The first extending plate extends in the extending direction. The second extending plate is separated from the first extending plate in the longitudinal direction. The second extending plate faces the first extending plate and extends in the extending direction. The extending intermediate plate extends in the longitudinal direction and the extending direction. The extending intermediate plate couples the first extending plate and the second extending plate in the longitudinal direction, and the extending intermediate plate has a curved surface.
