ABSTRACT:
Frames are described which can be made by plastics moulding and in which the (usually) four sides and the backing plate are moulded integrally in a single moulding operation. The backing plate does not quite fill the aperture between the four sides so it can be manufactured easily by injection moulding. The frame is suitable for the receipt of a sheet article such as a sheet of photographically sensitized paper between the backing sheet and flanges on the (usually) three sides other than that to which the plate is attached.
