As previously mentioned, the axial feed is automatically generated when cutting a thread by means of the lead screw, which drives the carriage.

如前所述，当依靠驱动大拖板的丝杆切削螺纹时轴向进给是自动产生的。

With the synchronous spindle the spindle rotation and the feed motion are synchronized by an electronic regulation according to the lead of thread.

根据螺纹导程，电力控制，主轴旋转和进给运动都是同步的。

The easy thread pulling during the manual material feed enables convenient and trouble-free handling when sewing the workpiece.

当缝制缝片时，在手动输送面料过程中缝线可被容易地拉出，使达到简便无误的缝制操作。
