The invention relates to a method for producing an adhesive closure element made of a thermoplastic synthetic material, by means of an extruder, which is produced without the need for screens, using a tempered forming cylinder () coated in rubber and a pressure cylinder in the form of a tempered pressure and smoothing cylinder. According to the invention, the synthetic material of a strip of film () is compressed by a wide split nozzle () of the extruder into pin holes () embodied as pocket holes in a rubber layer () which is arranged on the tempered forming cylinder (), said layer of rubber () and the pin holes being provided with a teflon covering. The pin strip () is guided by means of a tempered withdrawal cylinder () between a gap with a gap with a pression cylinder () heated to a temperature greater than 230&#xb0; C. and covered with PTFE at a low speed of between approximately 1 m/min. and 20 m/min. Alternatively, the pin heads () are formed by a plasma device () or by a plasma are () produced therefrom and the strip is displaced at a speed of between 12 m/min. and 200 m/min.
