    This machine is adopted with industrial computer control, screen displaying, imported double servo, three-servo or four-servo etc. Systems, synchronous length photo-electricity correcting deviation, two sets of frequency inverter, upper and lower heating sealing automatic control. It can make border-material adjustable and automatic winding, and make batch quantity output automatic with rational structure, simplicity of operation, stable performance, ease of maintenance, high precision, etc. Excellent performance.


    1. Use industrial computer or PLC to control servomotors and treat signals.

    2. Automatically unwind by tension control, automatically recity by EPC, automatically feed by variable frequency.

    3. Import double servo-control traction.

    4. Seal and press AC variable frequency motor driver.

    5. Use PC to control temperatures.

    6. Boast the function of producing double seeding bags, with precise producing bags, long tension control, smooth material putting, high production speed, long service life, and stable performance.

    7. Automatically accumulate quantity and batches, with presetting function.

    8. Punch by setting continuily, interval, or stop, and preset the punching time.

    9. Feed from one to six times.

    10. Preset the batch-sending quantity. The workable has the function of batch sending.
