Baughmann, K E

A system is described for insulating pipe with a foamed material, such as polyurethane, which includes an apparatus for forming a mold about the pipe into which the foam may be injected, apparatus for propelling the pipe through the mold, and support rollers for supporting the pipe before the foam sets without damaging or permanently deforming the foamed insulation. The molding apparatus may be a traveling mold in which mold-forming members travel about and along the pipe at substantially the rate of movement of the pipe, and a liner may be provided about the mold such as by a plastic film folding device. In the latter case, to aid in distribution of the foam about the pipe when injected, a barrier or dam means may be provided which is urged against the plastic film adjacent to the area where foam is injected.
