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、送料压脚具有倒缝送布量调节功能：在差动送料倒缝时可实现与下牙齿的同步送料，实现加固缝的平整美观。

1.lt has the function ofsynchronizingthe stitch length and differentialmomentum: when the stitch length changes, the upper differentialmomentum can besynchronously changed.

2.Feedingmethod: The feedingpresserfoot and lowerteeth are usedfor composite feeding,and the upper feedingis adjustable.

3.The feedingpresser foothasthe function ofadjustingthe fabric feedamountforreverse stitching: during differential feedingand reversestitching,it can realize synchronous feedingwith the lower teeth to achievea smooth and beautifulreinforced seam.
