摘要

P THE INVENTION CONCERNS SHEET TUBES 9 WHICH ARE PREFERABLY USED FOR SANDING SMALL DIAMETER TUBES. THE LINING TUBES INCLUDE AT LEAST ONE CONDUIT CHANNEL 23 WHICH CONTINUES ON THE LENGTH OF THE TUBE, FOR THE HOUSING OF THE SUPPLY LINES 28, THE SUPPLY LINES 28 WHICH CAN BE ARRANGED IN THE CHANNEL A DRIVING FROM OUTSIDE. TO CLOSE THE DUCT CHANNEL, A LID OR THE LIKE MAY BE USED. PREFERABLY, THE DUNNING TUBE IS CONSISTING OF AN OUTER TUBE 14 AND AN INTERIOR TUBE 15 MOUNTED COAXIALLY AND FIRMLY INSIDE THE FIRST, WHICH FORM A CONVEYOR TUBE, PARTICULARLY FOR ACCOMMODATING A CONVERTER WITH AN ENDLESS SCREW.
