1、具有针距与差动量同步功能：针距变化时可实现上差动量的同步变化。

2、送料方式：采用送料压脚和下牙齿复合送料，上送布量可调。

3、具有同步与差动功能：上差动送布量由控制面板上加减符号调节，并按需求调节同步送料或差动送料，实现了低张力缝制抑制了起皱、缝制错位等问题。

1. lt has the synchronization function ofneedle pitch and differential momentum:when the needle pitch changes, the upper differential momentum can be changedsynchronously.

2. Feeding method: The feeding presser foot and lower teeth are used for compositefeeding, and the upper feeding amount is adjustable.

3. With synchronization and differential functions: the upper differential feed amountis adjusted by the plus and minus symbols on the control panel, and synchronousfeeding or differential feeding, can be adjusted as needed, realizing low-tensionsewing and suppressing wrinkles, sewing misalignment, etc. question.
