Abstract:
1. A perforator/skimmer tab former having a plurality of edges and surfaces each edge of said plurality of edges being configured each relative to each other edge and each surface configured in relative position and geometry with each of said edges, said perforator/skimmer tab former comprising: said plurality of edges having a first edge, a fourth edge and two second edges, said first edge and said fourth edge being substantially at two opposing positions and said first edge elevated above said fourth edge, each of said two second edges substantially opposing each other and with the one end of each contacted with said first edge and the other end of each contacted with said fourth edge and wherein said first edge is the first cutting edge, each of said two second edges being the second cutting edges and said fourth edge being the roll edge, said first edge, when in use is advanced into said plastic within a valley region, and pierces and cuts through the material along one said edge and as said perforator/skimmer tab former is further advanced, each of said two second edges cause cuts and at the same time the plastic material within the cut region is pressed and rolled into the interior of the conduit by a roll surface while being substantially attached or hinged as a consequence of said actuatable perforator/skimmer tab former which may be sequentially and timely actuated to cause the perforation of the wall of pipe to be hinged along one edge particularly along the fourth edge called the roll edge; and said roll surface causing the rolling of said material being pierced and cut, having four ends and each of said four ends being substantially in contact with one portion of said edges, said rolling being directed into the interior region of said conduit being created with aperture/skimmer tabs, which said perforator/skimmer tab former, upon activation causes the creation of said aperture/skimmer tab as part of a conduction component for a leach processing system.
