Introduction:
1.Expansion and contraction of patterns: The pattern can be expanded or contracted part by part by 50—200% horizontally or vertically;
2.Frame driving: No quilting seam means only that the frame is moving along with the route of quilting seam;
3.Resetting of original points: Reset the initial point of patterns by its button at the original point;
4.Automatic patching: The quilted part can be back up and patched during working, and needn’t re-patch the finished products; 
5.Efficiency: The operation can be adjusted if the rotating shuttle is employed, so as to raise working performance;  
6.Structure: There is a high accuracy for patterns by using an AC motor and digital control for working. Prep stand for semi-automatic working;
7.Safety device: Computer, motor, machine, etc., which can shut down automatically if they are abnormal; the stoppages appear on the screen;  
8. 15-inch color-screen display: The color screen’s catalogue is processed in Chinese character, with easy operation. More information such as working process, stitch length, patterns and coordinate ＆#118alues can be displayed on the screen;
9.1G in-built harddisk: The 1G harddisk is used in an easy input way. One piece of disc can store 220 pieces of patterns at least;。
10.Memory: When the power is cut or power supply is cut off during working, it can continue to operate the prior working when re-switching on. In addition, patterns input in the memory are also maintained safely.
