The method involves determining flexible resetting force related to continuous deformation at a continuously extruded seal strand (1) transverse to a longitudinal direction of the strand. The resetting force is adjusted to a predetermined range by varying ...

The method involves extruding a sealing thread as a bent thread and bending the sealing thread after extrusion by plastic deformation and cooling of extruded material. Calibration elements (10) are directly arranged downstream in connection to extrusion of...
