Abstract
A pressurizing roller for use in a laminator to bond a film to a panel has a hollow outer shell and flanges on both ends. A roller shaft extending through the flanges and the outer shell transfers its angular moment of force via bearings directly to the flanges and via the flanges to the outer shell to provide uniform distribution of pressure by the roller outer shell to the film and panel. The outer shell is heated to a uniform temperature throughout.
Claims7
A pressurized roller for bonding a film to a panel by application of substantially uniform heat and pressure to the film and panel, comprising:
- a roller outer shell;
- a pair of flanges at opposite ends, respectively, of said roller outer shell;
- a roller shaft, to which an angular moment of force is applied, passing through said flanges and said roller outer shell and extending axially from both ends thereof;
- bearings located between said shaft and an inner diameter of said flanges to transfer said angular moment of force to said flanges and thereby to said roller outer shell;
- a shell heater located within said shell circumscribing said shaft;
- and
- a rubberized layer covering said roller outer shell.
