Abstract: A method for producing concrete pipes in a vertical casting mould comprising a moulding space (4) between a core (2) and a mantle (3) divided lengthwise and comprising mould sleeves (5, 9) which terminate the moulding space (4) at the bottom and at the top is described, wherein pourable concrete is poured into the moulding space (4) and the pipe body (7) is demoulded after setting of the concrete by opening the mantle (3). In order to be able to cast high-quality concrete pipes, it is proposed that the pourable concrete is poured into the moulding space (4) in a predetermined quantity when the upper mould sleeve (9) is removed and that the upper mould sleeve (9) forming a closed ring is pressed in a shaping manner into the end face of the pipe body (7) only after a setting time for a predefined setting volume of the cast pipe body (7) between the core (2) and the mantle (3).

Abstract: A method for producing containers filled with liquid content from preforms made of thermoplastic material. The liquid content is fed as a pressure medium into thermally conditioned preforms during a forming and filling phase in a mold of one of a plurality of forming stations arranged circumferentially spaced apart on a common, continuously rotationally driven working wheel. A compensating device compensates for thermal consequences of centrifugal force acting on the liquid content fed into the preform during the forming and filling phase. The compensating device imparts a temperature profile to the preform in a circumferential direction, which is not point-symmetrical in relation to a longitudinal axis of the preform to produce a thermally differentiated partial circumferential region. The preform is inserted into the mold such that the thermally differentiated partial circumferential region faces in a radial direction of the working wheel.
