Process: automatic loading of longitudinal bars, programmed transferring, loading and welding of cross bars + longitudinal transfer of the mesh for completion welding operations + transverse transfer of the mesh in the main jig + loading, bending of the ends and central “U” of the component called Loop and transfer to the main jig + withdrawal of the pre-bent frame from the warehouse, loading and transfer of the main template + transfer of the main template, rotation on a rotary table and advancement to the welding station + welding of the components on the frame, transfer and rotation of the components in the next station, insertion of the same into a dedicated jig + transfer, central welding of the door (Loop component), and final unloading.

The entire machine cycle is automatic, the only manual operations are related to production assistance, i.e.: replenishment of the bar warehouses, ordinary maintenance and cleaning, recovery for any machine downtime. Downstream of the line unloading, the finished product can be collected manually or by a robotic cell for storage.
