Abstract
A spinner apparatus for applying lining material to the interior of a pipe, the spinner apparatus having a cylindrical material accelerator coaxially positioned about a distribution manifold, the distribution manifold having a plurality of equally spaced, radially oriented slots extending from an axial chamber that receives lining material, wherein lining material is extruded through the slots onto the interior of the material accelerator and slung onto the pipe interior in an annular pattern. Movement of the spinner apparatus along the pipe produces a tubular lining member.
