Features
| The pressure on the web is equalized spacially. |  |
Sheet quality is maintained even with a worn belt. |
|---|---|---|
| Thermo bars can be adjusted even if the hot plates are deflected. | |
Because the web edges are not needlessly pressed, warping is less likely. |
| Heat conductivity is efficient because the Doublefacer belt is pressed | |
High speed double facing is possible even for heavy combinations and double walls. |
| Optional thermo weights can be installed in the cooling section | |
Will further suppress noise and flute crushing. |
Themo Bar Type and Weight Roll Type（Comparative Table）
Comparison Chart showing advantages of the thermo bar system over the conventional Weight Roller system
| Thermo Bar Type | Weight Roll Type （Convent.Type） | |
|---|---|---|
| Variation of Pressure on the web | GOOD: Variation among various web width. | Pressure varies among various web width |
| On Deflected Hotplates | GOOD: The Thermo Bars can conform to the deflection, so there is no crushing on the edges. | Web edges will get crushed on deflected hot plates. |
| Heat Conductivity Efficiency |
GOOD: Good heat transfer because the bars press by pads, not by rollers. | Heat transfer is not as good because the area of pressing is smaller. |
- On heavier webs, speed increases of 5 to 10 percent have been achieved.
- Easier to contain warping
- Noises have decreased by 5 to 10 dbs.
- Decreased need for steam shower.
- 50 percent less edge crush.
