Abstract
A double chain stitch sewing machine includes an upper section () and a lower section (), which can be displaced synchronously parallel to a sewing product plane () The upper section includes a needle rod () holding a needle (), and a drive () for displacing the needle rod perpendicularly to the sewing product plane. The lower section has a hook (), which reciprocates in a plane parallel to the displacement direction of the needle rod and cooperates with the needle to form the stitch At least one needle stabilizer (or) in the lower section can be displaced synchronously with the needle rod and hook displacements between a first needle position close to the needle path, in which the needle stabilizer supports the needle against deflection transverse to the displacement path of the hook ,and a second position offset from the needle path.
