Operation
Sleeper option
The Sleeper option shuts down the machine after a certain time.
The default setting is 10 minutes. If you wish to change this time,
please contact your supplier.
4.3 Sealing System
The sealing system closes the opening(s) of the bag to retain the vacuum and/or gas in the bag.
The end of the bag can optionally be cut off by the sealing bar.
Figure 2: Overview of the Sealing System
1.
Sealing bar
The sealing bar consists of the following components:
•
Sealing wires: during the sealing process, the sealing wires are heated for a certain time
causing the edges of the vacuum bag to melt together.
•
Cut-off wires (optional): A cut-off wire is heated in such a way that the foil of the bag
partially melts, allowing the excess foil of the vacuum bag to be removed easily.
•
Teflon tape: sealing and cut-off wires are covered with Teflon tape to prevent the bag from
sticking to the sealing bar.
Consult Replacing the Sealing Wire on page 55 for more detailed information about
maintenance.
2.
Silicone holder
Opposite the sealing bar is a silicone holder which provides counter pressure on the seal bag
(Replacing the Silicone Rubber of the Silicone Holders on page 56).
3.
Sealing mechanism
The sealing bars are pressed onto the vacuum bag by bellows. By connecting the inlet of
the bellows with the atmospheric pressure outside, they press the sealing bar onto the bag.
Additional sealing pressure (optional) may, depending on the model you have, be used if
additional pressure force is needed. See Technical Data on page 66 and Connecting the
Machine on page 21 for more information.
