Abstract: The invention relates to a machine for producing a tube provided with a nipple in each end controlled by a process-computer. The machine comprises a plurality of stations where machining of the tube shall be made, the tube primary product being rolled up on a roll which is arranged in a tube roll stand. According to the invention, the machine includes transport of the tube to and from respective stations wherein the tube is fed from the roll up to a measuring and cutting station, where the tube is measured to selected length and is cut off by a cutting tool; the tube is taken to a nipple connecting station, where the two ends of the tube are equipped with a nipple provided with a sleeve, which nipples, if necessary, are also marked; the tube is further taken to a pressing station, where a pressing unit presses the nipples to a fixed position on the tube; the machined tube is throughly cleaned by blowing and is finally controlled and/or tested, whereafter the tube is ready for wrapping.
