<p>The invention relates to a single-piece profiled body (1) consisting of an upper wall (6) which is provided with a passage opening (9) and comprising a transverse stiffening bridge (11) at each end of the upper wall. The inventive body internally delimits a first housing (13) which extends longitudinally between the two stiffening bridges (11) to house a driving mechanism used to move the table saddle in translation and at least one second housing (14) adjacent to the first housing (13) which can be used to mount means for guiding the table saddle in translation. Said body also comprises means for mounting seals which are used to close the passage opening (9) while allowing the passage of a part of the table saddle that protrudes in relation to the upper wall.</p> |
