1. A device for the semi-continuous blow moulding of fiber-reinforced, thermoplastic, endless, hollow-profile components with cross sections that are constant or varying in a longitudinal direction, comprising at least one consolidating tool which, in a closed state, encloses a preform, which encloses an elastically deformable pressure chamber, wherein:
a) a preforming unit and the at least one consolidating tool are arranged directly one after another;
b) the preforming unit provides the preform;
c) the preform enclosed by the at least one consolidating tool is a preform segment;
d) a central axis of the preforming unit, the at least one consolidating tool, the preform segment, and the pressure chamber are arranged congruently;
e) the at least one consolidating tool is designed in at least two parts; and
f) the at least one consolidating tool corresponds to a contour of the component;
wherein:
the at least one consolidating tool has at least two independently isothermal-tempered tool segments, and in that the tool segments are arranged along a middle axis;
dimensions of the at least one consolidating tool, the pressure chamber, and the preform segment for processing are identical along the central axis;
the device has a feed device which is capable of repeatedly moving the preform by an amount of a length of one of the tool segments into a machining direction directed along the central axis;
the pressure chamber is formed from:
an endless, deformable pressure membrane and sealing elements, or
a pressure membrane that is a deformable hose firmly attached to sealing elements; and
the pressure chamber is pressurizable.
