1. An automatic machine for making curvilinear tubes or boxes covered with paper or cardboard and having a curvilinear outline, having a conveyor for conveying to a covering station a tube or a box having a first and a second end, wherein thecovering station comprises:a first sub-station equipped with a spindle, able to engage in the tube or the box and cause it to rotate relative to a horizontal axis, and operating in conjunction with a feeder for linear feed of a pre-glued covering sheet, so as to connect the covering sheet to an outer wall of the tube or the box;a second, folding over sub-station equipped with a folding over device operated on command for covering the second, open end of the box with an excess edge of the covering sheet projecting from said second end, wherein the folding over device comprises a contact element connected to a carrier to be movable radially with respect to the tube or box engaged by the spindle, from a first position, at a distance from the tube or box, and a second position, wherein the contact element, in the second position, interferes with said excess edge of the covering sheet while the spindle rotates the tube or box about its axis. 2. The machine according to claim 1, comprising: means for forming a curvilinear box having a bottom, stably joined to a first end of a tube with a curvilinear outline, andmeans for applying a pre-glued disk to the bottom to close the first end of the outer wall. 3. The machine according to claim 2, wherein the means for inserting the bottom in the outer wall comprise a first gripper element for holding and conveying the bottom. 4. The machine according to claim 2, wherein the means for applying the pre-glued covering disk comprise: a disk supporting surface, having an opening whose shape and dimensions match the outer outline of the box,a second gripper element able to move relative to the disk supporting surface, to hold and move the box,a contact surface able to move relative to the supporting surface, which can be inserted through the opening and is opposite the element relative to the opening,means for moving the contact surface until it is drawn near the disk resting on the supporting surface,means for moving the second gripper element until the box is placed on top of a pre-glued side of the disk resting on the supporting surface and forcing the box through the opening so as to apply a peripheral portion of the disk to a stretch of the wall adjacent to the first end. 5. The machine according to claim 4, wherein the contact surface is supported by elastic means. 6. The machine according to claim 4, wherein the contact surface has a shape and dimensions which allow it to be superimposed to the end of the wall. 7. The machine according to claim 1, wherein the station is an operating station of a rotary carrousel equipped with a plurality of operating stations. 8. The machine according to claim 7, wherein the station spindle is mounted at one end of a carrousel arm and can rotate relative to an axis of rotation. 9. The machine according to claim 1, wherein the means for covering a second, open end of the box comprise a curved element in a fixed position relative to a box covering motion, the position being such that it interferes with the edge of the pre-glued sheet in such a way as to fold the edge into the box and so cover the inner stretch of the wall adjacent to the open end. 10. The machine according to claim 1, wherein the means for covering a second, open end of the box comprise pressure rollers configured to press the folded edge onto the wall. 11. The machine according to claim 1, wherein the means for forming a curvilinear box comprise means for feeding a succession of open tubes and means for centering the individual tubes relative to a predetermined position for insertion of a bottom in a positioned tube. 12. The machine according to claim 1, wherein the means for applying an adhesive disk comprise means for feeding a succession of adhesive disks and means for placing and centering a box over one of the disks. 13. The machine according to claim 1, wherein the covering means comprise a belt for feeding a succession of covering sheets and means for aligning the direction of sheet feed relative to a predetermined direction. 14. The machine according to claim 1, wherein the means for covering a second, open end of the box with an edge of the sheet comprise a counter-mould. 15. The machine according to claim 1, comprising at least one disk or tailstock which can be drawn near and into contact with the boxes at the covering stations and/or at the folding over stations.
