The subject of the invention is a method of framing pictures, especially paintings on canvas, in a frame protecting the picture against slipping out of frame composed of channel sections, ends of which, bevelled at appropriate angles and adhering to each other are connected in the resulting corners by means of angle brackets inserted into channels of said sections. The essence of the method consists in that to the inner surfaces of all sides (16) of a polygonal picture canvas (15) with its corners (17) cut off at angle (?), strip-like stiffening elements (18) are glued, and after wrapping the stiffened picture sides (15) around outer surfaces of channel section elements (2) of folding frame (1) and folding them over upper faces of outer wings (19) of said elements, said stiffened picture sides are located in channels (6) of section elements (2), and then tightened along their whole length by means of string tightening elements (1 1) located also in channels (6), and further, in each corner of frame (1) created by adjoining section elements (2) and their channels (6), flat bar elements (7 and 8) of bendable angle brackets (5) are planted, bent earlier at appropriate angle (ß, ß' or ß"), together with elastic strips (9) joining said flat bar elements, that, together with their protruding ends, adhere to the stiffened picture canvas sides (15). |
