Pneumatic side cutter: 

Where are pneumatic side cutter and traditional side cutter different? 

Traditional side cutter driven by the part from machine mechanism, so its means blade will continues moving when machine running .
However, about our design, we use a small cylinder to drive the blade working, operated with sensor and control box, about timing of cutter and number of cutting times are adjustable by control box, ex sample: we can adjust 2 times or 3 times of cutter working time at beginning or ending. Make blade more durable, it will not need to change blade very often.
This device operated with thread tension relax device ( adjusting thickness between threads, let thread out from needle plate smoothly then cut off, effectively save threads) and air blower (blow air assist makes the thread inhaled easier ) Easy to operate, no gesture request.
