Abstract

A method for producing an elongated article with a sheath. The sheath is extruded with a predetermined wall thickness in an extrusion unit. Following the extrusion unit in a feeding direction, a part of the still moldable material is built up with the aid of a molding unit during a molding process such that a molded part forms integrally on the sheath. The molding unit is moved according to the following working cycle: the molding unit is accelerated from a starting position in the feeding direction, then it is advanced in the direction of the elongated article and the molded part is formed, the molding unit is withdrawn from the elongated article, and the molding unit is decelerated and moved from an end position, counter to the feeding direction, back in the direction of the starting position.
