Abstract

The invention relates to a method and a device for manufacturing a pipe shell from an insulating material by means of which the cycle times can be further reduced while the quality of the pipe shell is simultaneously improved, by at least one web (29) of the insulating material which is provided with a binding agent being wound around a core (19) by means of at least two opposing belts (12, 13) which wrap around the core (19) partially. The method steps are characterized in that the at least one wound-up web (32) of insulating material is removed in a radial direction of the core (19) which is, however, not opposite to the direction in which the at least one web (29) of insulating material was fed by the one belt (12), especially by the wound-up web (32) being discharged through the same belt (12).
