(19) In an embodiment, the invention can involve a process where a reinforcing layer is placed between at least two layers of polymer. The reinforcing layer includes continuous wire filament in an orthogonal or an irregular arrangement and a grid like mesh.

(20) This embodiment reinforces polymers, such as high density polyethylene, low density polyethylene, and polypropylene, in a spiral wound extrusion process. This embodiment may see use in other processes of manufacturing such as injection molding, compression molding, vacuum molding, and the like. The reinforcing or mesh layer extends between layers of heated polymer as the extruder moves along, continually wrapping the polymer and mesh upon the mold.

(21) A roller gang presses a later layer of polymer upon the mesh and fuses it to a prior layer. The mesh generally extends for the length of the desired finished product. The mesh has a grid like form with filaments of a flat cross section, bonds and merges with the polymer, and provides additional strength against compressive loads.

(22) In this embodiment, the mesh materials may have a coating of polyethylene, polypropylene, polyvinyl chloride, ultra high molecular weight polyethylene, polyvinylidene fluoride, Kynar, or have no coating. In an alternate embodiment, the mesh is replaced with a glass rope, metallic wire, Kevlar, or other continuous material.

(23) In this embodiment, when the drum rotates with the spiral wound strip applied to it and the extruder moves slowly to the length of the desired cylinder, the extruder emits a strip of polymer, often seven inch wide by inch thick. During the wrapping of a spiral strip, reinforcement material enters the strip automatically from a spool of glass rope, metallic wire, Kevlar, or other continuous material.

(24) The reinforcing material embeds between a first layer of polymer or mesh and a second adjacent layer of polymer or mesh. The width of the reinforcing material may measure larger or smaller than the strip of applied polymer. The reinforcing material may have a mesh structure and bonds one strip to an adjacent strip. The reinforcing material undergoes a fusion, chemical bond, or physical bond with the polymer under action of the roller gang.

(25) The roller gang presses the molten polymer through the openings of the mesh of reinforcing material. This pressing of polymer into the mesh creates a full fusion between a first layer of polymer, reinforcing material, and a second layer of polymer. The innermost layer of a strip has solely polymer while layers outwardly merge reinforcement between every other layer.

(26) The placement of reinforcement continues between a second and third layer of polymer strip, a third and fourth layer of polymer strip, and additional layers and the embodiment continues this process until the desired thickness appears for the finished product of pipe.

(27) The embodiments have mesh reinforcement that increases the strength of the polymer cylinder, pipe, or flat sheet in compression resistance, shear resistance, elongation, and creep prevention. The reinforcement allows for reducing the thickness of the polymer in a finished product while maintaining the desired structural properties. The reinforcement can influence the expansion and contraction coefficient of the polymer. For example, adding a metal mesh will decrease the expansion and contraction of the polymer due to raising temperature environment.

(28) The embodiments can allow for creation of cylinders for a pipe and flat sheets made by cutting a warm plastic cylinder along its length, measure upon the drum. The cut former cylinder, warm and viscous, then is pulled off the drum and set upon a flat surface for cooling. A flat sheet then has dimensions of the length of its parent cylinder, a width of pi times the diameter of the parent cylinder, and the thickness of the parent cylinder's wall.

The layer A 200 was placed upon the cylinder 2 ahead and before the layer B 201 by the roller gang. The roller gang then compresses layer B 201 upon layer A 200. The compression continues as the drum turns and the cylinder moves laterally to the right, as previously shown in FIG. 10.
