摘要:
A sewing machine having a reciprocatory needle (9) and a reciprocatory thread-take-up device (17) to deliver thread (11) to the needle (9) 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 (11). The thread control device (16) can have an opposed plate (25) and spring wire (24) between which the thread runs and which cooperate to apply spring pressure to the thread. Downstream thereof a thread brush (27) can be employed through which the thread runs. The thread (11) can be further lightly tensioned and laterally positioned by the thread brush (27). The guide plate or other device can include catcher structure to catch thread escaping the take-up device. The thread control device can help control premature descent of the thread and improperly tensioned stitches.
