Abstract
An embossing apparatus in an extrusion line for the production of sheet extrusions like vinyl siding, can include a revolver above the backing roll and supported in a pair of cradles so that selected embossing rolls can be juxtaposed with the backing roll and can define the embossing gap therewith. The revolver is indexed in position by pneumatically-operated locking members on the cradles. The revolver allows embossing roll change on the fly, if desired.
