The working phases of a section bending machine can be identified as:

Loading of the part to be bent: in this phase the profile is insert in between the rolls. The part can be supported if necessary and is not subject to deformation stress.

Roll movement in order to achieve the pinching position: during this phase the profile is blocked in between the rolls and can be moved forward and backward rotating the rolls. The pressure exercised is lower than the one necessary to deform the profile

Working phase: in this phase the pressure increases and the deformation of the profile takes place, by translation of the profile and movement of the rolls.

Unloading of the profile: the pressure on the profile is eliminated and is increased the space between the rolls, so that the profile can be extracted from the machine.

1. A profile bending machine is a machine used to perform cold bending on profiles with different shape and size. Usually the machine is used in the metalworking field to bend profiles like tubes, bars, angles, “T” profiles, “U” profiles and beams.
2. The most important part of the machine are the rolls (normally 3) that apply a combination of forces on the profile, the resultant of which determinates a deformation, along a direction perpendicular to the axis of the profile itself.
