Device for producing plastic pipes
The device for producing corrugated plastic pipes comprises an extruder (1) with a die head (2), and a corrugator (3) with mold jaws (10) running in pairs. In order to form the pipe, the plastic melt tube is introduced into the molding section (55). In the region of the inner mold surface (200), the mold jaws are subjected to vacuum by a vacuum device (50) through vacuum channels, which are formed in a section of the mold jaws delimited by a parting surface (100) and cooperate with channel inlets on the outer side. In the section delimited by the rear side of the mold jaws, coolant channels (40) are formed which form a net-type and / or grid-type structure composed of sections connected to one another in a zigzag and / or serpentine.

Textured core sheets for fluid drainage unit
A core sheet includes a primary textured surface and separate secondary cuspations or corrugations. The core sheets are configured for use within a fluid or wastewater treatment unit that typically includes one or more fabric layers. The primary textured surface enhances retention of wastewater fluid received by the unit, which over time causes an increase in build-up of biomatter on the surface, which in turn enhances the efficacy of treatment of the wastewater. An inline process of making the core sheet includes extrusion forming a smooth flat sheet from raw polymeric material and immediately feeding the smooth flat sheet through texturizing rollers, followed by rolling flat textured sheets. Cuspations are added to the flat textured sheets, optionally at a different site, and then cut to preferred dimensions for incorporation into a wastewater unit.
