ABSTRACT:
An apparatus and method for coating an elongated pipe wherein a web is coated with a liquid coating composition in a stationary trough and wound spirally around the pipe by turning the pipe over the trough. While the pipe is turned, a web dispenser moves substantially parallel to the rotational axis of the pipe and the dispensed web passes around an elongated bar positioned within the trough to cause the web to be pulled through and coated with the liquid. Movement of the web dispensing means relative to the trough causes the coated web to travel along the bar in a direction transverse to the direction in which the web is dispensed. The web also may travel along a friction member extending substantially parallel to the rotational axis of the pipe so as to tension the web before it is coated.
