Abstract:
Method of manufacturing an adhesive fastener with a plurality of interlocking means in the form of stems having thickened parts at their terminal end and formed in one piece with a substrate,in which process a shapeable material in a plastic or liquid state is fed to the nip between a pressing tool and a shaping tool and these are driven such that the substrate is formed in the nip and conveyed in a transport direction, in which a screen having throughgoing cavities is used as the shaping element on the shaping tool, and in which the interlocking means are formed in that the shapeable material hardens at least partially in the cavities of the screen, characterized in that the side of the screen facing away from the pressing tool has a second shaping element interacting with its cavities, by which the shapeable material is shaped in the area of the outer ends of the stems characterized in that a film with projections which extend into the cavities of the screen is used as the second shaping element arranged on the inside of the screen and in that depressions in the ends of the stems formed from the plastic are created by these projections.
