Definitions

  • the present invention relates to a procedure for bending a profiled metal element in one or more dimensions and associated apparatus .
  • This restraining force counters the tendency of the cross section of the element to become deformed, thus ensuring that it retains its original shape.
  • apparatus which is known per se in the art and is only schematically illustrated in figure 2 , and includes a template 16 having the shape to be imparted to the metal element and a series of dies 18 operated by respective actuators 20 able to press the element 10 against the template 16.
  • the jaws 26 of the pincers 22 are operated by respective actuators 28, which may be mechanically, pneumatically hydraulically or electrically operated.
  • the pincers can be replaced by vices, operated by mechanical lever systems instead of actuators .
