Abstract
A material casting assembly for a pipe lining apparatus, the assembly having a housing mounted onto an extension/retraction arm and containing an impingement block controlled by an impingement valve, and a static auger bounded by a rotating cylinder which defines a mixing path to an extrusion chamber. The rotating cylinder has exit ports through which lining material is expelled from the extrusion chamber onto a pipe wall.
