The invention relates to a double chain stitch sewing machine comprising an upper machine section (10) and a lower machine section (12), which sections together define a sewing product plane (14) and can be displaced in a synchronous manner parallel to said plane. According to the invention, the upper machine section (10) comprises a needle rod (18), which can be displaced perpendicularly to the sewing product plane (14) by means of a drive (28) and which holds a needle (20), and the lower machine section (12) comprises a hook (40), which cooperates with the needle (20) to form the stitch and which can be displaced back and forth on a plane that runs parallel to the displacement direction of the needle rod (18). At least one needle stabilizer (42, 44) is located in the lower machine section (12). Said stabilizer can be displaced synchronously with the needle rod and hook displacements between a first needle position that lies close to the needle path, in which it supports the needle (20) that is lowered into the sewing product against a deflection that is transversal to the displacement path of the hook (40) and a second position at a distance from the needle path.
A double chain stitch sewing machine with a machine upper section (10) and a machine lower section (12), which sections between themselves define a sewing product plane (14) and are moveable in synchronism parallel to said plane, the machine upper section (10) having a needle rod (18) movable perpendicularly to the sewing product plane (14) for holding a needle (20) and the machine lower section (12) having a hook (40) cooperating with the needle (20) for forming stitches, which hook is movable back and forth in a plane parallel to the movement direction of the needle rod (18), characterized in that at least one needle stabilizer (42, 44) is arranged in the lower machine section (12) and is movable in synchronism with the needle rod movement and the hook movement between a first position near the needle path, in which first position it supports the needle (20) plunging into the sewing product against a deflection laterally to the movement path of the hook (40), and a second position remote from the needle path.
