ABSTRACT:
A method for forming a coved backsplash system, comprising two adjacent perpendicular wall sections joined by a curved corner joint. In particular, a designed relief, or groove, is formed on the rear surface of the material at a predetermined depth. The grooved material is placed on a shaped mandrel having the capacity of maintaining controlled heating, limited to the area being formed on the material. The grooved area is also heated by a device in conjunction with the surface area being heated by the mandrel. The solid surface material is brought to a thermoforming temperature by conductivity of the heat generated in the mandrel and heating devices. A wiping arm is used to form the solid surface material to the mandrel, the solid surface material being brought in contact with a flat work surface by the wiping arm. The non-grooved, flat surface areas of the material are then held in place by the wiping arm while the solid surface material begins the cooling process. After cooling, the heating devices are retracted, the material returning to its original rigidity. A back up piece is affixed to the solid surface with an adhesive strengthening the area of the thermoforming.
