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.
Apparatus for applying sheet material around an edge or corner of a carrier member, said apparatus comprising a frame, a support arrangement for the carrier member for supporting it in a predetermined position, a pair of end supports rotatable in unison, a pair of laterally offset primary frame members extending between and attached to the two end supports, an applicator bar extending along the required length of the support arrangement, means carried by one of said primary frame members for urging the applicator bar towards the surface of a carrier member supported by the apparatus, and away from said primary frame member, means for causing rotation of said end supports which causes lateral movement of the applicator bar relative to said surface while remaining in contact therewith, and lateral restraining means carried by the other primary frame member for inhibiting uncontrolled or undesired lateral movement of the applicator bar.
