Device for guiding a lower thread in a sewing machine |
摘要 |
A device for guiding a lower thread in a zigzag stitching sewing machine is provided with a lower thread guiding unit that determines two lower thread drawing positions in accordance with a selected pattern. The lower thread guiding unit includes a lower thread guiding part which, at one of the two positions, acts on the lower thread to guide a lower thread drawing position to a center of a needle amplitude. A lower thread releasing element, at the other of the two positions, cooperates with the lower thread guiding unit to release the lower thread engaged with the lower thread guiding part.
