Abstract (en)

A sewing machine having a reciprocatory needle (9) and a reciprocatory thread-take-up device (17) to deliver thread to the needle employs a thread control device (16) located between the thread take-up device (17) and the needle (9) to engage and apply light tension to the thread. The thread control device can have two opposed plates (24,25) between which the thread runs and which cooperate to apply spring pressure to the thread, for example, a guide plate (25) and a spring plate (24). The guide plate (25) or other device can include catcher structure (37) to catch thread escaping the take-up device (17). The thread control device (17) can help control premature descent of the thread and improperly tensioned stitches.
