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.
