Abstract
In a process for manufacturing finite extruded profiles (3) from elastomer material with at least one projecting sealing lip (12) of different contour (32) over the length of the profile, for simple and very accurate manufacture the invention proposes that by means of two needles (10, 11) which act laterally on the sealing lip (12) and whose depth of contact (a) is controlled by a cam disk (5), the specified contour configuration (32) in the corresponding profile area (12) is incised in the form of grooves and the projecting profile section (38) severed after vulcanization (FIG. 1).
