1. Touch screen is adopted for input control and machine status display, so as to finish machine

correction easily.

2. Equipped with originally imported SIEMENS electrical system and servo motor drive, to make the

machine run steadily.

3. Germany SICK photoelectric detector is used to track the material to be printed, reduce the

adjusting time and improve production efficiency

4. Separate single-station unwinding rollstand with hydraulic lifting device; Convex-type inflatable shaft

for loading material (or shaftless loading); Magnetic powder brake for unwinding and automatically

constant tension controller for unwinding tension control; EPC web guide control system for material

alignment; alarm function for reminding replacing material and stopping-machine device for

detecting material broken.

5.   The handle making component is an independent machine, which is driven by servo motor and

synchronized with the main motor; handle length is adjustable according to bag size.

6. The cutting and gluing of paper handles are controlled by servo motors, as synchronous as the tub

cutting of the main machine; contact rollers transfer pattern is adopted in gluing paper handles;

vacuum suction pattern is adopted in transferring handles onto conveyer belt; handles are

compressed onto the paper web with a series of pneumatic rollers, to ensure the pasting strength.

7. Adjustable forming mould structure (side sealing is above the forming mould); automatic

glue-spraying device with automatic disengaging function is used for side gluing.

8. Rotary serrated cutter (or flat-blade cutter) with elliptical gears is used for cutting; the cutting length

can be corrected by SICK photoelectric detector; Multi-layers bottom forming drum, center grippers,

second tuck clamps, and drum grippers are adjustable for ease of changeover; automatic

disengaging function (bottom gluing is prevented for empty feeding to avoid contamination to the

surface of the drum).

9. Paper bags are delivered by belt, and collected at side workbench, which is easy for operations;

automatic counting function.
