A paper baking-pan for cooking cakes has a pleated containing portion (3) provided with an upper rim (7) folded to the outside and defining a loop (12a) within which a string (12) pulled along the whole perimetrical extension of the upper rim is housed. According to the process for producing the baking-pan, the string is introduced into a longitudinal folded rim (7) of a flat paper strip (14) before pleats (13) are carried out thereon. Afterwards during the pan assembling steps, the paper strip (14) is wrapped according to a frusto-conical configuration around a flat element (19) forming the pan bottom and fastened thereto. By a final die-forming step the upper rim is folded over externally of the pan, causing the complete opening of the pleats in the vicinity of the upper rim and the simultaneous tensioning of the string. <IMAGE>
