ABSTRACT:
A sewing system that is smaller and more simple in construction than the prior art. The cloth holding means and cloth clamping means are part of a X-Y-Z motion apparatus that is supported solely from the top arm of the sewing system frame.
Because the spaced twin needles of the sewing system will be required to penetrate up to 14 layers of thick cloth in some anticipated applications, considerable rigidity and stability is imparted to the single needed clamp that supports the two needles by reciprocating the needle clamp with two symmetrically spaced needle bars. This minimizes canting of the needle clamp and bending of the needle bar, thereby assuring more uniform stitch lines and minimizes missed stitches.
