ABSTRACT:
A helical structure having a shaft defining an axis of rotation and a substantially helical flight extending about the axis of rotation and composed of a plurality of sections each having a segment disposed in substantially right angular relation to the axis of rotation. A method for manufacturing a helical structure or the like including the steps of producing a mold having a mold cavity defining a configuration for the helical structure having a substantially helical flight composed of a plurality of sections having segments disposed in substantially right angular relation to an axis of rotation for the helical structure, introducing a moldable substance into the mold cavity to form the helical structure in the configuration and removing the helical structure from the mold cavity by separating the mold along a path substantially aligned with the segments. An apparatus for manufacturing a helical structure or the like, the apparatus including a first mold body having a mold cavity defining a first portion of a configuration for a helical structure having an axis of rotation with a substantially helical flight extending thereabout, a second mold body having a mold cavity defining a second portion of the configuration, and a structure for releasably interconnecting the first and second mold bodies for movement to and from an assembled relationship only along a path substantially right-angularly related to the axis of rotation of the configuration.
