ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a process for manufacturing a decorated sheet or plate and specifically to a process for manufacturing a decorated sheet or plate in which the decorations are applied in liquid or semiliquid form.
DESCRIPTION
The object of the present application is to obtain a new product for ornamental use and interior decoration, in a practical, rapid manner that can be applied industrially.
The subject matter of the present invention is a process as described herein. A product and a device as described herein also form the subject matter of the present invention.
According to the new process, a base plate or sheet of transparent or translucent plastic material or glass is prepared, for example a sheet of rigid polymethylmetacrylate (Plexiglas) or of flexible polyester, preferably 76 or 100 &mgr;m thick. Dots or areas of paint are then applied to said sheet, using, for example, a so-called nitrosynthetic paint, preferably transparent and colored, and allowed to dry. The paint is applied using a board with pointed projections in a punctiform or linear pattern, which will hereafter be called the “cliché”. The cliché is partially immersed in a tank containing the paint or plastic, then raised and lowered onto the base sheet. The cliché is them raised and the sheet with the application is allowed to dry. The sheet with the decoration can then be used alone, or incorporated into a panel with transparent surfaces, or else incorporated into a panel with a mirror surface facing the sheet; or otherwise a plurality of sheets, preferably with a different arrangement of the applications, can be assembled to form a panel. The sheet and the panel constitute new products. The process and the device make it possible to obtain the product industrially, in a practical and economical manner.
An exemplary embodiment will be described hereunder with reference to the attached drawings in which:
FIG. 1
