Claims
- 1. An apparatus for aiding the removal of an adhesively coated web from a surface of a rotating roll at a first temperature, the apparatus comprising:
a moveable belt disposed about at least a portion of the surface of the roll defining a contact region, the belt having a second temperature that is different from the first temperature such that as the web passes between the surface of the roll and the belt, the adhesively coated web is cooled to third temperature that is different from the first temperature.
- 2. The apparatus of claim 1 wherein the belt is air permeable.
- 3. The apparatus of claim 1 further including a means for cooling the belt.
- 4. The apparatus of claim 1 further including a vacuum plenum disposed adjacent at least a portion of the belt.
- 5. The apparatus of claim 4 wherein the vacuum plenum cools the belt by passing air over at least a portion of the belt.
- 6. The apparatus of claim 4 wherein the vacuum plenum provides a vacuum that can be used to help remove a web that is passed between the belt and the roll from the surface of the roll.
- 7. The apparatus of claim 1 wherein the contact region is at least about 10 degrees of the surface of the roll.
- 8. The apparatus of claim 1 wherein the roll has a first width and the belt has a second with that is less than the first width.
- 9. The apparatus of claim 1 wherein the difference between the first temperature and the second temperature is at least about 28° C.
- 10. The apparatus of claim 1 wherein the belt includes one or more of the following: steel, alloys of steel, Aluminum, alloys of Aluminum, stainless steel, or alloys of stainless steel.
- 11. The apparatus of claim 1 wherein the belt includes a filler including one or more of the following: alumina, limestone, silica, gypsum, metals or metal oxides in powder or filament form.
- 12. The apparatus of claim 1 wherein the filler has a heat capacity of at least about 0.09 cal/gm oC.
