Automatic packaging line to pack profiles and rotor

A packaging line to pack profiles having a U-shaped or a C-shaped cross-section formed by a first side wall, a second side wall and a base wall between the first and second side walls, the packaging line comprising:

• a first conveyor and a second conveyor to transfer profiles, the first conveyor and the second conveyor spaced from and parallel to each other;
• a head block to move upward and downward, the first conveyor and the second conveyor to transfer profiles to an area beneath the head block;
• and
• a rotor, carried by the head block, to couple to a first profile transferred by the first and second conveyors with a concave side of the first profile facing upwards, the rotor to rotate the first profile such that the concave side of the first profile is facing downwards over a second profile, a concave side of the second profile facing upward, the rotor to release the first profile to insert at least a portion of the first profile into the second profile to form a duplex, the rotor including:
• a body;
• a first set of magnets arranged in a first row along a longitudinal axis of the body;
• and
• a second set of magnets disposed outward from the body in a direction that is perpendicular to the longitudinal axis of the body, the first set of magnets to engage a side wall of the first profile and the second set of magnets to engage a base wall of the first profile.
