Abstract
Wrapping apparatus for a pipeline joint is disclosed. The preferred and illustrated embodiment incorporates a set of rollers which carry the body of the mechanism around a pipeline at the bare weld. The apparatus carries a roller and the roller dispenses sheet wrapping material. The apparatus has a framework which is somewhat similar to a clamp mechanism, having a throat which enables it to open and close and thereby clamp the mechanism to the pipe. It is adjustable to accomodate pipes of different diameters.

An apparatus for placing a cigarette wrap of insulative material around a pipe at a bare place prior to placing the pipe in the ground, comprising:
- two sets of first, second and third alignment rollers;
- a framework supporting said two sets of first, second and third rollers which positions said two sets of rollers in contact with a pipe to be coated, and wherein the two sets are spaced apart from one another and where said rollers being spaced around the pipe to clamp said framework to the pipe while yet permitting the framework to rotate around the pipe one revolution which rotational movement is supported on said rollers;
- and
- supply means carried by said framework for receiving and dispensing insulative material in sheet form directly onto the pipe with a specified tension and alignment and between said two sets of rollers to place one turn of such material on the pipe and wherein said supply means carries the sheet of material around the pipe to place a cigarette wrap thereon.
