The primary component of a sewing machine needle that clamps into the needle holder is the shank. In the context of a 134 needle, a standard industrial sewing machine needle type, this element provides the secure connection between the needle and the machine. Its cylindrical form allows for insertion and fixation, facilitating the transfer of motion necessary for stitching.
The integrity of this specific needle section is critical to consistent stitch formation and prevents needle breakage. A properly designed and manufactured one ensures the needle remains aligned during high-speed operation. Historical development in sewing machine technology has focused on refining its design for better compatibility with various industrial sewing machine models.
