A rubber strip manufacturing method that includes a step of extruding a rubber from an extrusion orifice of an extruder includes: a step of forming a long rubber member by extruding the rubber from the extrusion orifice that is circular; and a step of forming a rubber strip by passing the long rubber member through a gap between a pair of rotating rollers. The gap has a shape that is the widest in a central portion in a direction parallel to rotation axes of the rollers and that narrows as a distance from the central portion increases.

Disclosed herein is a method of forming a bioadhesion resistant article comprising extruding a material through a die bearing a pattern of protrusions such that the extruded material has a surface having a series of parallel splines above a base surface, and applying pressure with a first patterned template to the surface of the extruded material such that the series of parallel raised splines are formed into discrete raised segments of varying length; where the patterned template comprises grooves that are inclined at an angle α to the splines. The method further comprises applying pressure with a second patterned template to the surface of the extruded material, where the second patterned template contains grooves that are inclined at an angle β to the splines.

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then it is advanced in the direction of the elongated article and the molded part is formed, the molding unit is withdrawn from the elongated article, and the molding unit is decelerated and moved from an end position, counter to the feeding direction, back in the direction of the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.
