Abstract

A picture such as a photographic print is formed to a concave/convex configuration for aesthetic reasons by fixing the flat print to a flat sheet or mount with an interposed adhesive, the assembly then being press formed between heated matched dies to provide the curvature. The heating prevents unsatisfactory results due to air bubbles. <IMAGE>

Description

MOUNTING PICTURES TO PRODUCE A DOMED SURFACE This invention relates to a method of mounting pictures. The term "picture" is used herein to relate principally but not exclusively to photographic prints.
Pictures are normally mounted to provide a required rigidity, and usually a flat surface is provided. The object of the invention is to mount the pictures on a domed surface for aesthetic reasons.
My previous Patent Application No. 8701576 describes a method of mounting a picture which involves assembling the picture to a sheet metal mount with an interposed adhesive, and then pressing the assembly between matched dies so that the sheet metal assumes a domed configuration, for example is generally convex/concave and the picture is maintained in that configuration as it adheres to the sheet metal mount. An essential feature of the said previous Patent Application was the provision of a hole in the sheet metal, and it was found that that hole was necessary to avoid entrapped air forming air bubbles in the adhesive causing the picture to have a lumpy appearance.
The present invention aims to solve the lumpiness problem without the necessity of providing a hole in the sheet metal.
According to the invention, a method of mounting a picture comprises assembling a picture on a flat sheet metal mount with an interposed adhesive, and pressing the assembly between matched heated dies. Preferably a temperature of the order of 500C is used, and the assembly is held between the dies for a short time, typically of the order of 30 seconds.
By these means, it is unneccessary to provide the hole and lumpiness is still avoided.
The invention has been practiced experimentally with fine art reproduction prints and also with photographic prints. In the latter case, modern photographic paper is usually resin coated and it is thought that the heating effect of the resin coating helps to maintain the pressed shape.
Also, in the case of photographic prints, the invention has been practiced successfully with both glossy and matt prints, although the latter are easier in that there is a possibility of some surface bruising occurring which may be visible on a glossy print.
The invention is more particularly described-with reference to the accompanying drawings wherein: Figure 1 shows the picture and the flat sheet metal plate of similar size and shape.
Figure 2 shows the plate and picture being assembled together after one or the other has been coated with a contact adhesive, possibly after the adhesive has been allowed to dry to a tacky state, depending upon the characteristics of the employed adhesive.
Subsequently, the picture and metal plate are applied together, and possibly additional pressure is used for example by rolling, squeezing or pressure between flat dies.
Figure 3 shows the assembly marked out so as to provide a generally elliptical picture, which may then be cut from the assembly, as shown.
Figure 4 shows a flat mounted picture being moved between a pair of matched dies which are then moved together and held to form the assembly into the required curvature.
The picture may be on the concave side of the assembly but more usually will be on the convex side.

Claims (5)

1. A method of mounting a picture comprises assembling a picture on a flat sheet metal mount with an interposed adhesive, and pressing the assembly between matched heated dies.
2. A method as claimed in Claim 1 wherein a temperature of the order of 500C is used, and the assembly is held between the dies for a time, of the order of 30 seconds.
3. A method as claimed in Claim 1 wherein the assembly of print and mount are trimmed to a circular or oval shape prior to pressing.
4. A picture assembled to a mount and formed to a concave/convex-by the method as claimed in any of Claims 1-3.
5. A picture assembled to a mount and formed to a concave/convex configuration substantially as described.
