Method of operation:
The WV (angle sealer) and the GV (straight-on sealer) are 3-lug sealers for cartons.
In the case of the WV the carton enters the machine with the short side leading as the top lid is being bent down. Afterwards glue (or hot air) is being applied to the long side to be sealed and the main lid is being closed. During the second step, after the 90° angle, glue or hot air is being applied to the short sides and the side lugs are being closed.
In the case of the straight-on sealer GV the closing of the main lug is similar, but as the speed is much higher so the cartons are being fed in continuously. After the 90° turning station the side lugs are being closed in a similar manner as in case of the WV.
Optionally a lug-control system is available to be located at the outfeed of the machine.
