Abstract
Apparatus for applying a two component coating material to a surface defining a cavity. The apparatus includes injection means for injecting coating material into the cavity and means for generating a turbulent region into which region the coating material is injected and for dispersing the coating material radially outward toward the surface. The present invention also employs a novel method for applying a coating to the surface of a symmetrical cavity comprising the steps of advancing a coating apparatus mounted at the end of an elongated support member into the cavity to be coated and applying the coating to the interior surface of the cavity.
Claims2
An apparatus for applying coating material to a surface defining an essentially symmetrical cavity comprising:
- a first means for injecting a resin coating component having a first plurality of outlets;
- a second means for injecting a catalyst coating component having a plurality of outlets each one of said plurality of outlets of said second means being associated with one of said first plurality of outlets;
- a rotatable shaft;
- a turbine comprising a disc coupled to said shaft, a plurality of radially disposed blades, each of said blades being mounted for rotation on said disc such that said plurality of outlets is spaced from said blade;
- and
- means for rotating said rotatable shaft;
- wherein said first and second means inject the resin coating component and the catalyst coating component into the region of turbulent air a spaced distance from said blades, such that the first coating component and the second coating component are mixed together and said mixture is dispersed radially outward toward the surface to be coated.
An apparatus for applying a coating material to a surface defining a cavity comprising:
- injection means for injecting coating material into the cavity, said injection means including means for providing a first coating component and means for providing a second coating component, said first and second means being coupled to plurality of output ducts;
- a rotatable shaft;
- means for rotating said shaft, including means for selectively reversing the direction of rotation of said means for rotating;
- and
- a turbine comprising a disc attached to said shaft and having a plurality of radially disposed blades each having an end, each of said blades being attached by its end to said disc, wherein said output ducts for said coating components are spaced from said blades.
