The unwinding using magnetic powde r brake and rewinding tension control system transmits the signal from to the inverter the precision encoder variablefrequency motor. It can realize closed-loop vector control. Main traction is controlled by variable frequency motor and inverter, the tension is stability. The unwinding device adopts no-shaft pneumatic conic type. The rewinding device adopts pneumati c slip shaft. Advanced photoelectric automatic correction controller and meter counter can realize automatic inspection, deviation rectifying, counting and alarm. This machine is suitable for longitudinal slitting plastic materials like OPPN BOPP、 PE、PP, etc.
Applacation:GFQ1200 high speed longitudinal slitting machine is suitable for longitudinal cutting OPP, BOPP,PE, PP and so on.
