Sealing of Valve Bags |
 |
To enhance the sealing accuracy
of the AMO Valve Sealer, a separate press belt conveyor is necessary.
This applies pressure to flatten bags that have become rounded while
filling. It cleans the valve to improve the strength of the adhesive
and coordinates the timing for sending bags to the sealing machine.
AMO engineers all aspects of conveyors needed before and after sealing
processes. |
 |
The AMO Valve Sealer applies
a heater plate and cooler plate in turn to the valve. (The diagram
to the left illustrates the progressive stop-start method of sealing.)
To obtain the highest sealing efficiency, AMO offers solutions based
on consideration of type of bag, valve and adhesive, temperature,
the state of the valve after the bag has been filled, and other factors. |

High-Capacity Type |
 |
Capacity of the sealing process can be further raised with a high-capacity
sealing machine.
Angling the bag enables continuous movement of the line. This method
allows processing of about 1,400 bags per hour. Moreover, the high-capacity
sealing machine can be adapted for bags of various sizes, arriving
at random on the same line. |

The AMO Valve Sealer automatically
closes adhesive-type valves and seals the bags. Having
achieved automation
