The present invention essentially relates to a process for curing pipe insulation, including the employment of a two-part mold and the utilization of a device for the passage of curing air through the mold and through a pipe insulation preform which is arranged around a core disposed within the mold. The process for the curing of insulating chutes constituted of a fibrous materials, such as wool or the like, completely avoids the formation of any burrs which can conceivably be formed between interengaging and cooperating mold halves, one of which is a female and the other a complementary male component. A sharp and flexible leading edge in the male part is arranged to come into contact with the inner surface of the female part and to slide therealong before making contact with a preform for producing the pipe insulation, which is preferably a thermal wool material.
