Abstract (en)
In a method for producing a tubular article (1) having a circumferential accumulation of material, the tubular article (1) is formed with first engagement means (6) for engaging corresponding second engagement means on a separate ring (5), which is pushed over the article (1) to the position where the accumulation of material is to be provided until the engagement means are brought into permanent engagement with each other, so that axial displacement of the ring (5) is prevented and the accumulation of material is formed. The method is especially well suited for producing such bottles as are to have a circumferential thick flange at the opening (4). A device for carrying out the method comprises a tool having means (7) for expanding the ring (5) and applying it on the article (1) in the position where the accumulation of material is to be provided, thus establishing the engagement between the cooperating engagement means. <IMAGE>
