Solutions for bridge sewing machine and broken thread

To solve the problem of bridge and disconnection, different methods of treatment should be adopted depending on the causes of bridge and disconnection:

Bridge and disconnection solutions caused by needle problems

(1) do not use blunt needles, they should be checked regularly and replaced in time.

(2) a blowing device is installed next to the needle to accelerate heat dissipation from the needle.

(3) use needles with a special surface treatment. The needle coated with Teflon film can reduce the resistance to friction between fabric and fabric when sewing, prevent the needle from generating too much heat, prevent the suture from melting by the heat of the needle and the fusion of chemical fiber thread debris, and prevent thread jumpers, disconnections and other phenomena.
