Abstract
The disclosure is of a method and means for applying a flowable coating material, such as relining, to a tubular stack; e.g. chimney, flue or the like, by means of a distributor moved upwardly into the stack while supplying coating material to an upper surface of the distributor which is configured to cause the material to flow outwardly to the wall to adhere thereto. The apparatus includes selectively added extensions for moving the distributor incrementally through the length of stacks of considerable height, preferably by means of power-operated means; e.g., a fluid-pressure device.
Claims15
Apparatus for applying a flowable coating material to a limited sector only of an interior wall of a tubular stack such as a chimney, flue and the like in a single pass, comprising:
- a distributor disposed at a starting point in the stack, said distributor having an upper surface sloping downwardly and laterally toward only the wall sector to be coated;
- coating material supply means;
- means for conducting coating material from said supply means to the upper surface of the distributor for flowing to said wall sector;
- means for advancing the distributor in the stack while the coating material is supplied to said upper surface for coating the wall sector continuously during advance of the distributor;
- gage means for causing the distributor to follow the wall sector as it advances;
- means for discontinuing supply of material to the distributor;
- and means for causing return of the distributor to its starting point.
A distributor for applying a coating material to a limited sectorial interior wall portion of a tubular stack such as a chimney, flue and the like comprising a member having a horizontal marginal edge portion adapted to follow the limited wall portion only said member further having a high portion spaced above said plane and laterally from said edge portion, a spreading surface sloping from said high portion to and meeting said edge portion, and means adjacent to said high portion for receiving coating material for flowing across the spreading surface to said edge portion.
