A method and device are provided to change the curvature of the seam of the tip of stockings wherein a sewing machine is utilized in correspondence with a rotating, circular, horizontal plane for supporting the flattened tip of the stocking to be sewn with a suspended coaxial plate with alternating vertical motion and jointly rotating for holding the tip of the stocking steady during the sewing. A device is disclosed for gripping in several points, separately, the free end of the flattened tip of the stocking to be sewn which projects beyond the rotating sewing plane (4). A pneumatic arrangement is provided for activating and deactivating, respectively, the gripping device. A device is provided for moving the gripping means (14) in a longitudinal direction from the sewing plane (4) for obtaining an elastic extension of the fabric from the tip of the stocking having been gripped and a motion of approach to the rotating sewing plane to obtain the rectilinear motion of return in the initial position having allowed the gripping of the stocking: structure is also provided for synchronizing the actions of the gripping device of the stocking with those of the above-mentioned plate of the sewing machine.
