US Classification:

4251331, 2642098, 425381, 425382 R, 4253824

Abstract:

A pipe extrusion die may be provided having an inner flow passageway having a first cross-sectional area, and an outer flow passageway having a second cross-sectional area, both being in communication with an inlet flow passageway. A ratio adjusting tube may be movably disposed in blocking engagement between the inlet flow passageway and the inner flow passageway. The ratio adjusting tube and the outer flow passageway both may be substantially concentric with the inner flow passageway. Material may be distributed from the inlet flow passageway to the inner and outer flow passageways. The method and apparatus may allow for the manual and automatic control of the proportion of material distributed between the inner and outer flow passageways by adjusting the position of the ratio adjusting tube in relation to a passageway between the inlet flow passageway and the inner flow passageway, based on various operating parameters.

B28B 3/12

US Classification:

26417129, 425363, 156391

Abstract:

A method of pressing an outer wall of polymer pipe is provided. The method includes extruding a layer of polymer onto a pipe to form an outer wall of pipe; conveying the pipe including the outer wall of pipe through a pressing apparatus having a pressing element configured to rotate about the pipe; and urging the pressing element against an exterior surface of the outer wall as the pressing element rotates about a pipe conveyed through the pressing apparatus. An apparatus for pressing an outer wall of polymer pipe is also provided.

US Classification:

264505, 264515, 264571, 264154, 264155

Abstract:

A method of deforming an outer wall of polymer pipe is provided. The method includes: forming dual-wall pipe having a smooth wall and a corrugated wall; extruding an outer wall of pipe onto the corrugated wall of the dual-wall pipe; penetrating the outer wall of pipe with a vacuum punch; and drawing a vacuum between the corrugated wall and the outer wall via the vacuum punch; wherein the vacuum drawn between the corrugated wall and the outer wall causes the outer wall to deform in a direction towards the corrugated wall. An apparatus for forming an outer wall of pipe and a mold configured to form a coupling preform in a segment of continuously-extruded and molded polymer pipe are also provided.

International Classification:

B29C 47/20

US Classification:

4251331, 425192 R, 425380, 425466

Abstract:

A method and apparatus is provided for distributing material through a multilayer pipe extrusion die. A first flow passageway, having a first cross-sectional area and extending along a first flow direction, may be connected to a second flow passageway, having a second cross-sectional area substantially the same as the first cross-sectional area of the first flow passageway, to provide a second flow direction different from the first flow direction of the first flow passageway. A conical passageway may extend from the second passageway toward a dispensing outlet. Material may be distributed from the first flow passageway into the second flow passageway. The method and apparatus may generally maintain the same flow properties of the material at a point before and after the connection of the first flow passageway and the second flow passageway. The flow properties of the material may be altered proximate to the outlet.

Abstract:

A system is disclosed for manufacturing multi-wall corrugated polymer pipe. The system includes an extruder configured to co-extrude concentric annular tubes; a corrugator configured to form the concentric annular tubes into a dual-wall pipe having a smooth wall and a corrugated wall; a cross-head die configured to extrude an outer wall of pipe onto the corrugated wall of the dual-wall pipe; a vacuum punch configured to penetrate the outer wall of pipe and draw a vacuum between the corrugated wall and the outer wall, such that the outer wall of pipe deforms inward toward the corrugated wall of pipe between bell and spigot portions of the corrugated wall; and a cutter configured to cut the pipe into sections where the vacuum punch deformed the outer wall between the bell and spigot portions of the corrugated wall. A method of manufacturing multi-wall corrugated polymer pipe is also disclosed.
