A cross-beam for a vacuum hold-down table formed by a monoblock section upon which a vacuum hold-down table is fitted and movable on slides. The monoblock section houses a first tubular chamber which extends along its length and is connected to external vacuum source. A part of the first chamber has an opening on which a magnetic seal with a plurality of evenly distributed holes is placed and fitted over this seal on the outside of the monoblock section first chamber is a deformable strip of magnetic material which is movable from one position which closes the first chamber to another position which opens the said chamber during the passage of a deflector unit on the strip which is fixed to the vacuum hold-down table and connects the first chamber and vacuum hold-down table at any point on the monoblock section.
