Use Of A Splitter Bar; Presetting The Tension - SEAL 62S Betriebsanleitung

4. Push both sides of the shaft firmly into their supports.
5. Turn the shaft until the grippers lock in.
6. Position the film and the scrap core in the middle and align them.
Note:
When both upper and lower section are used, place both films at exactly the same
position.
7. Make sure the films (and scrap cores) are set up and aligned properly.

Use of a splitter bar

The splitter bar has two functions:
• When processing film with release liner, it is used to split the release liner from the film.
• When processing heat sensitive film it is used to reroute the film to increase the
contact surface with the heated roller.
Figure 16: Use of a splitter bar.
Film with release liner (A) is running via the splitter bar where the release liner is split off.
Pressure sensitive film without release liner (B) would leave adhesive remains behind on
the splitter bar, so this is lead over the splitter bar
Heat activated film (C) needs as much contact surface with the heated roller as possible.
Therefore this film is lead underneath (via) the splitter bar.

Presetting the tension

To enable the film to unwind without wrinkles tension (brake) can be set to the roll.
On the right-hand side of the machine you will find tension control knobs, corresponding
with each shaft.
Turn the tension control knob clockwise to set the tension or counter clockwise to release
the tension.
Note:
The unwind/wind-up shafts in the bottom half have a split tension setting: Turn
clockwise for unwind tension and counter clockwise to release the unwind tension.
Turning further counter clockwise will set wind-up tension (see also section 0).
When the film is webbed, it is recommended to set a low tension to each shaft by turning
the knob clockwise until you feel some resistance.
On the unwind shaft this will prevent film from unwinding without tension. On the motor-
driven wind-up shaft it allows the shaft to slip and adapt its rotation speed to the speed of
the film.
