Line for producing metal profiles for plasterboard false ceilings

A line for producing metal profiles for plasterboard false ceilings, the line comprising in sequence along a profile advancement direction:

• a profiling machine suitable to profile a metal strip to obtain a continuous metal profile;
• a cutting group placed downstream of the profiling machine and suitable to cut said continuous metal profile into pieces of predefined lengths which constitute said metal profiles for plasterboard false ceilings;
• a punching group placed downstream of the cutting group and suitable to make holes on each metal profile along a longitudinal extension thereof;
• and
• an extraction system for extracting finished metal profiles from the punching group,
• said line further comprising a management and control unit configured to control at least said cutting group and said punching group,
• wherein said punching group comprises:
• a first portal press having a first punching head elongated along a first operating direction;
• and
• a second portal press having a second punching head elongated along a second operating direction, parallel to said first operating direction and staggered with respect thereto along said profile advancement direction, and
• wherein the first punching head of said first portal press is longer than the second punching head of the second portal press, said management and control unit is configured to alternately operate in use said first portal press or said second portal press as a function of type or the predefined lengths of the metal profiles output from the cutting group;
• wherein said first portal press is configured to process at most from 25 to 30 pieces/min said second portal press is configured to process at most from 40 to 45 pieces/min.

• a group for applying coupling terminals that is suitable to apply coupling terminals to both ends of each of the metal profiles;
• wherein said group for applying coupling terminals comprises two coupling terminal application heads aligned along a coupling terminal application direction parallel to the first operating direction and to the second operating direction, and wherein said two coupling terminal application heads are movable along said coupling terminal application direction to adapt to the predefined lengths of the metal profiles to be processed;
• wherein said two coupling terminal application heads are mounted on motorized carriages sliding on guides parallel to said coupling terminal application direction, and wherein said management and control unit is configured to operate in use said motorized carriages so as to adjust a position of said two coupling terminal application heads along said coupling terminal application direction as a function of the type or the predefined lengths of the metal profiles in output from the cutting group.
