Abstract A plastic laminating apparatus for laminating plastic sheet material to a countertop core having a backsplash attached at right angles thereto during a single pass through the apparatus. The apparatus consists of a plurality of longitudinally spaced work stations through which the work is successively moved for progressively shaping and adhering the plastic laminate to the work, such work being guided through the apparatus by receipt of a downwardly projecting portion from the work in a guide track extending the entire length of the apparatus. A back die bends the laminate to conform to the general shape of the backsplash and countertop after heating, and fingers and pressure rolls are used to progressively bend and press the projecting edges of the laminate into firm contact with the edges of the countertop and backsplash. Floating cutters are also used to trim the excess laminate material extending beyond the countertop and backsplash edges, and such excess material may be picked up by a suction blower or removed by a rotary brush prior to passage through final pressure rolls.
Edge trimming apparatus for removal of any excess plastic laminating material projecting beyond an edge of a workpiece comprising a stationary base plate, a movable support plate having one end pivotally connected to said stationary base plate, spring means interposed between said stationary base plate and movable support plate for urging said movable support plate away from said stationary base plate, said support plate having a guide shoe thereon urgeD into engagement with the workpiece by said spring means, and a cutter blade carried by said support plate for trimming any excess plastic laminating material from the workpiece when engaged by said guide shoe, and means for advancing the workpiece past said cutter blade.

The apparatus of claim 1 further comprising support rails for the workpiece, and holddown means for pressing against the workpiece in opposition to said spring loaded support plate to maintain the workpiece in engagement with said support rails.
Claim 4
Dependent Claim
23 words
The apparatus of claim 2 further comprising plural rollers on said support rails providing rolling engagement of the workpiece along said support rails.
Claim 5
Dependent Claim
116 words
The apparatus of claim 1 wherein there are two of said stationary base plates with movable support plates pivotally connected thereto and urged away therefrom by spring means interposed between said stationary base plates and movable support plates, and guide shoes and cutter blades on each of said support plates, one of said support plates being mounted for vertical pivotal movement about a horizontal pivot toward the bottom of a workpiece for trimming any excess plastic laminating material therefrom, and the other support plate being mounted for horizontal pivotal movement in spaced relation from said one support plate about a vertical pivot toward one side of the workpiece for trimming any excess plastic laminating material therefrom.
