Abstract
A sewing machine for forming running-stitch seams, comprises a needle provided, proximate to its tip, with an open eye and orientated so that its axis is substantially perpendicular to a surface for supporting the item being sewn. The needle is actuated with a reciprocating motion along its own axis passing cyclically through the supporting surface. A thread take-up wheel is provided below the supporting surface and is composed of a fixed part, with a magazine for the taken-up thread, and a rotatable part, rotationally actuated about its own axis. The rotatable wheel part supports a lower looper engaging the thread loop below the supporting surface to load the thread in the magazine formed in the wheel fixed part. Pneumatic tensioning means for the thread portion lying below the supporting surface are further provided.
