METHOD AND APPARATUS FOR CHANGING THE INCLINATION OR ORIENTATION OF A LONGITUDINAL TAB OF AN EXTRUDED WEATHER STRIP FOR MOTOR VEHICLES DURING ITS EXTRUSION AND WEATHER STRIP THUS OBTAINED

Mfg. elastomeric strip with variable section lip - using two movable, opposing needles on die ring to cut into extrudate lip before vulcanisation

The process involves (i) extruding the strip (3) at the max cross-section; (ii) cutting grooves in the extrudate lip (12) with two opposing needles (10,11), the operating level of which can be progressively varied by a cam (5); (iii) removing the excess material after extrudate vulcanisation. The appts. includes an adjuster (4) in front of the extruder die ring (1) with metal needles (10,11) inclined relative to one another. The adjuster is spring-tensioned (7) against a plunger (6) in contact with the cam (5) the profile of which corresponds to the change in lip contour height. Raised projections on the cam (5) surface cause the needles (10,11) to make vertical cuts in the lip at the predetermined strip length. USE/ADVANTAGE - For mfg. profiled elastomeric strips of defined length, having a lip with varying cross-section along the length. The cutting action does not cause any further deformation of the unvulcanised lip and a clean cut edge is obtained.

Extrusion of tubes and sheaths

In the prodn. of extruded branched pipes or sheaths, a second retractable die with at least two moving parts (9B) is at the outlet of the die (2) at the extruder tube head, which can be moved together and apart from each other. A main mandrel (7), at the tube head, has at least two dividing mandrel rods (8a, 8b) extending in parallel from the extrusion die (2), from the end of the main mandrel (7). When the moving parts (9B) of the second die are brought together, their shape structure divides the cross section of the extrusion from the main die (2) with two extra dies round the dividing mandrel rods (8a, 8b), to give simultaneous extrusion of two tubes (T2, T3). When the moving parts (9B) are separated, the main die (2) extrudes a single tube (T1). Also claimed is an appts. with an extruder tube head with a second retractable die with at least two moving parts (9B) which can be moved towards and away from each other. The parts, when brought together, divide the cross section of the extrusion from the main die to form at least two dividing dies. Two dividing mandrels (8a, 8b), in parallel, are in front of the main die at the end of the main mandrel (7).

The invention relates to the processing of polymeric materials and can be used in the manufacture of corrugated floor slabs for livestock buildings. The purpose of the invention is to expand the technological capabilities of the head. The extrusion head comprises a housing made from upper and lower plates. The working surface of the top plate is made with protrusions. The top plate is driven by a horizontal reciprocating rotation relative to the bottom plate. The side surfaces of the plates are cylindrical and interconnected. Due to the possibility of the upper plate turning during extrusion relative to the lower one, zigzag wavy longitudinal stripes are formed on the product surface. 5 il.

Tapered hollow pole extruder

Hybrid extruded articles and method

The present invention discloses extruded articles, such as tubing or multilumen catheters, having hybrid composition, an axial length and a transverse cross-section orthogonal to the length. The extruded articles have unitary construction and require no assembly. The composition of each cross-section of the article along the length of the article is homogeneous and comprises a first extrudable material and/or a second extrudable material. The percentage of the two extrudable materials in any cross-section varies along the length of the article in a controlled, either continuous or discontinuous manner. The first and second extrudable materials are preferably elastomers having different durometers, color or radiopacity. The weight percentage of one of the two extrudable materials in a cross-section may vary abruptly, smoothly and/or periodically along the length of the article.
