New cage welding machine with variable spreading round-oval-round (patented)

With our new cage welding machine it is possible to produce cages with variable, intermeshing geometry.
In the production process, the reinforcing cages are flowed from one shape to another one and back to the first again, for example round-oval-round. Thus, the tensile stresses, which are located in the concrete pipe by 90 ° in different diameter ranges, will be covered by only one reinforcement cage.
This is achieved by the new development of a spreading system, in which the linear movement of a main spreading drive is divided into different linear movements of the individual sliders, each holding a longitudinal. A particular challenge now lies in the hydraulic control of two, partly in synchronism, partly in the controlled counter-direction hydraulic drives.
