Output (English): The present invention relates to an apparatus for producing a shaped polymer frame (20, 52) on a flat part (1) having top and bottom main surfaces (22, 52) and a peripheral edge (23), which apparatus comprises: an extrusion head (25, 40, 55) having a body that defines a recess for receiving the peripheral edge (23) of the flat part (1) and portions of the main surfaces (22, 21) adjacent thereto; at least one sealing ledge (31, 42), which is movable between the (1) retracted position, which allows entry of the flat part edge into the recess, and (2) an engaged position in contact with one of the main surfaces (22, 21)  of the flat part (1) wherein an open area is defined between the extrusion head (25, 40, 55) body, the sealing ledge (31, 42) and the flat- part (1) in the shape corresponding to that of the polymer frame (52). The extrusion head (25, 40, 55) is either fixed or movable only in vertical direction and the apparatus further comprises means (66) for moving the flat part (1) relative to the extrusion head (25, 40, 55), whereby the moving means (66) advances the flat part (1) through the recess and during movement of the flat part (1) a polymer is put in said recess, defined between the extrusion head body, said at least one sealing ledge and the flat part (1), on the flat part (1) edge (23) and on a portion of at least one of the adjacent main surfaces (22, 21) thereof forming thus the polymer frame (52) of the flat part (1).
