The invention concerns pneumatic equipment to support and block elements to be machined on a worktable of machine tools. It comprises a number of suction cups (13) mounted on the worktable (11), connected to an aspiration group, movable and able to be positioned in height above the worktable, characterized in the fact that each suction cup (13) is attached to a cap support (23), connected to a spherical head (21) and movable in all directions between a horizontal and a sloping position with regard to a vertical axis (X), and in the fact that the cap (23) is associated with an additional control device (17) to establish and define the horizontal position of the suction cup and a means of pulling (27) to vary the position of the suction cup, starting from said horizontal position, in reply to the application of an external force.
