The invention provides a covered edge width adjusting device and an overedger with the same. The covered edge width adjusting device comprises a needle plate, needle falling holes are formed in the needle plate, a thread sliding piece is arranged on the side edge of the needle plate and provided with a thread hanging end for suspending a sewing thread, the thread hanging end of the thread sliding piece is located at one side, parallel to the surface of the needle plate and perpendicular to the feeding direction, of the needle falling holes, and the thread sliding piece is fixed through a thread sliding piece fixing and adjusting part and can move in the direction parallel to the surface of the needle plate and perpendicular to the feeding direction. According to the covered edge width adjusting device and the overedger with the same, as the thread sliding piece with the adjustable position and the thread hanging end is arranged, multiple covered edge widths can be adjusted, the overedger provided with the needle plate of one specification can achieve multiple covered edge widths, and the covered edge width adjusting device is simple in structure and convenient to install and adjust.
Description
technical field [0001] The invention relates to the field of sewing machines, in particular to a hemming width adjusting device and an overlock sewing machine with the adjusting device. Background technique [0002] Sewn fabrics of different thicknesses correspond to different hemming widths, and the existing overlock sewing machines can only realize one hemming width when equipped with a needle plate of a certain specification. If the hemming width needs to be adjusted, needle plates of different specifications need to be replaced, which brings inconvenience to the adjustment of the hemming width. Moreover, different hemming widths need to be equipped with needle plates of different specifications, which leads to the need for a sewing machine to be equipped with different needle plates, which brings corresponding storage problems, and frequent replacement of needle plates leads to high cost and low sewing efficiency Wait for a series of questions.
