With high performance of No.781,the highest sewing speed is 3600rpm;With the use of computer servo motor and direcl-driven way,it can start up sewing rapidly,save resources effectively,and reduce cost,which can saves about 50%when compared with ordinary machine.Thick materials can be sewed easily through strengthening 550V servo motor,even if the penetrating power is strong;without crashes between starting bract and upper wheel,rapid electromagnet draw bar starting mode can lighten laborsfatigue and improve work efficiency.Control functions of cloth-feed cam with the use of optical inductor,so that adjustment becomes much more simple and convenient.Mechanical wear is avoided through programming of electric cabinet.
