<p>An apparatus for performing a mechanical work operation on a frame (6) for a door or window, the frame (6) being formed by a plurality of section bars (2, 3, 4, 5), comprises:
- conveyor means (13, 14, 32, 33) for conveying the frame (6) along an advancement direction (F; F1) towards a working zone (12);
- a working unit (7) arranged in the working zone (12), the working unit (7) being movable along a movement direction (M) parallel to the advancement direction (F; F1) for working on a first section bar (2) of the frame (6);
- gripping means (17, 31) suitable for engaging with a second section bar (3) of the frame (6) in order to keep the frame (6) stationary during the work operation;
- a support device (27) for supporting a portion of the first section bar (2);
- a transverse blocking device (29, 30) for blocking said portion transversely to the movement direction (M) during the work operation, the support device (27) and the transverse blocking device (29, 30) being movable with the working unit (7) in order to engage with different portions of the first section bar (2).
