ABSTRACT:
Apparatus for applying a surfacing sheet such as a plastic sheet, veneer or the like to an optionally radiused edge of a panel, or to a column or the like, in which an applicator bar which is, optionally heated and is preferably flat, is urged against the surfacing sheet to press it onto the surface of the panel column or the like. Means are provided for ensuring that lateral movement of the applicator bar takes place relative to the panel or column to stretch and smooth the surfacing sheet onto the surface of the panel or column. The applicator bar is preferably carried on an arm arrangement held between two spaced rotatable end supports and the biasing is carried out by a number of spaced pneumatic or hydraulic piston and cylinder assemblies acting transverse to the arm arrangement. The biasing means is preferably carried on a frame member carried by the rotatable end supports. The surfacing sheet being applied, which may easily be subject to damage, is protected by a protective sheet interposed between the surfacing sheet and the applicator bar.
