A suitable automatically operating apparatus is proposed for producing reinforcing cages (3, 4) for rectangular pipes made of concrete. Longitudinal-wire sections (5), which are parallel to the pipe axis, are held together in a framework (9). The latter essentially comprises a perforated frame (13), which cannot be moved in the longitudinal direction, and a receiving frame (18), which can be displaced relative to the perforated frame. Rectilinear transverse-wire sections, angles or bent brackets are welded onto the longitudinal-wire configuration, to be precise onto the respective side surfaces of the longitudinal-bar configuration in a freely selectable manner. Fitting apparatuses which can be displaced perpendicularly with respect to the longitudinal-wire sections are used for this purpose. In addition to the wire thickness, it is also possible to select the spacings between the transverse-wire sections provided in each case. In the example, the framework (9) can be rotated about a vertical axis on a carousel (10), in each case two mutually opposite fitting apparatuses interacting with two welding apparatuses arranged transversely thereto. The necessary transverse-wire sections are finished off in each case during the welding operation. The completed reinforcing cages (3, 4) are removed, and inserted one inside the other, by crane (19 to 25).
