Pressure Setting - SEAL 62S Betriebsanleitung

Pressure setting

Thin images
When processing thin images (printer output, posters, etc.) pressure is preset when the
upper and lower material is webbed.
When the leader panel or release board is through the nip, the nip is set to zero and
pressure is preset.
The best pressure setting for thin films is about 80%.
During processing the pressure can be adjusted.
Panels
When processing panels, a leader panel is used to web the film(s). This leader panel is at
the same time used to preset the pressure.
Use a leader panel of the same material, thickness and width as the panels to process.
1. Set the nip to the thickness of the panel.
2. Feed the leader panel into the nip in slow mode.
3. When the edges of the film(s) are through the nip, set the pressure to approximately
80% for full-width panels.
CAUTION:
For narrower panels set the pressure proportional to the width between 40%
and 80%. E.g. half width equals 60%.
Mounting boards
The panel to be mounted can be used to set the nip and pressure.
1. Set the nip to the thickness of the panel.
2. Feed the panel into the nip in slow mode.
3. When the panel is halfway in the nip, set the pressure between 70 and 80% for full-
width panels.
CAUTION:
For narrower panels set the pressure proportional to the width between 40%
and 80%. E.g. half width equals 60%.
4. Back-up the panel out of the nip
Note:
The image will add approximately an additional 5 to 10% to the pressure.
