摘要:
A sewing machine (1) comprising a frame (2) onto which a main motor (3) is mounted, the latter being connected through main driving means (4) to first actuating means (5) acting directly upon stitch-building means (8). Said sewing machine (1) further comprises means for conveying a fabric (17), which shift the fabric onto which seams are made, and second actuating means (15), and it is characterized in that it comprises a secondary motor (11), which is also mounted onto the frame (2), whose operation is driven by control means (20) and secondary driving means (12) for transmitting motion from the secondary motor (11) to the second actuating means (15).
摘要:
The machine comprises a needle (1) with an open eye (2) orientated perpendicular to a supporting surface (3) for the sewn item (4) and actuated with reciprocating motion to pass cyclically through the supporting surface and the sewn item, carrying a thread loop; a thread take-up wheel (5) having a fixed part (6), with a magazine (8) for taken-up thread (12), and a rotatable part (7); a lower looper (11) engaging the thread loop below the supporting surface (3) and loading the thread (12) into the magazine; and comprises a thread handly unit (31,32) allowing correct formation of the stitches.

摘要:
A sewing machine for forming running-stitch seams, comprises a needle (1) provided, proximate to its tip, with an open eye (2) and orientated so that its axis (1a) is substantially perpendicular to a surface (3) for supporting the item being sewn. The needle (1) is actuated with a reciprocating motion along its own axis (1a) passing cyclically through the supporting surface (3). A thread take-up wheel (5) is provided below the supporting surface (3) and is composed of a fixed part (6), with a magazine (8) for the taken-up thread, and a rotatable part (7), rotationally actuated about its own axis (5a). The rotatable wheel part (7) supports a lower looper (11) engaging the thread loop below the supporting surface (3) to load the thread (12) in the magazine (8) formed in the wheel fixed part (6). Pneumatic tensioning means (14,15,16) for the thread portion lying below the supporting surface are further provided.

The rotatable part (7) supports a lower looper (11) engaging a portion (12a) of the loop that protrudes from the eye (2) along one side of the needle (1). A thread disengager (13) is provided for disengaging the thread (12) from the needle (1) which engage the portion (12b) of the loop of thread (12) protruding from the eye (2).
