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).

Disclosed herein is a tool for forming a composite part. The tool comprises a first layer, a second layer, spaced apart from the first layer, and a low-density core interposed between the first layer and the second layer. The low-density core has a density less than the first layer and the second layer and comprises a plurality of empty cells at least partially defined by the first layer and the second layer. The tool also comprises a heating source and one of: each one of the plurality of empty cells extends across a width or length of the first layer and the second layer; or adjacent ones of the plurality of empty cells are fluidically interconnected by a fluid port formed in the low-density core.

A method of finding a target conveying capacity of a pumping includes a temperature-control flow through a temperature-control channel carried out according to a control variable by using a throttle as an actuating element such that a temperature-control volume flow remains substantially constant. A conveying flow of the pumping system is measured, and a pump starting from a starting conveying capacity independent of the control of the temperature-control volume flow is driven such that a conveying capacity of the pumping system is reduced to a reduced conveying capacity. Then, a check is made to find whether the conveying flow remains substantially constant and, if this is the case, the reduced conveying capacity is determined to be the target conveying capacity. If this is not the case despite the control of the temperature-control volume flow, the starting conveying capacity is determined to be the target conveying capacity.
