17 the printing unit 3 is likewise constructed as a flexographic printing unit with a uv dryer 18 disposed laterally to the side of the impression cylinder 17 the printing unit 4 shows a flexographic printing unit with a hot air dryer 19 arranged underneath the impression cylinder 17 the embossing unit 8 has two interacting cylinders 21 22 the substrate web 9 is guided through a pressure nip formed by the two cylinders a lower cylinder 21 serves as an impression cylinder for an upper embossing cylinder 22 the embossing cylinder 22 has a cylinder body 23 which is fabricated from a non magnetizable material for example aluminum a ceramic composite material or a cubic face centered steel an induction coil 24 is arranged on the cylinder circumference in such a way that the coil winding is wound over the circumference of the cylinder the coil winding is connected to a current generator 25 the embossing cylinder 22 bears a cylinder shell 26 in the form of a sleeve which covers the induction coil 24 the cylinder shell 26 is produced from a non magnetizable material a further sleeve namely a u201c tool sleeve u201d 27 can be pushed laterally onto the cylinder shell 26 the tool sleeve 27 is produced from a non magnetizable material for example aluminum ceramic composite material or plastic etc the sleeve is a carrier body 27 for embossing tools 28 the embossing tools are produced from magnetizable material for example cubic body centered steel when the induction coil 24 is energized by way of feeding current from the current supply 25 e g a current generator g a magnetic field is generated this leads to the heating of the magnetizable materials that are located in the magnetic field of the coil in.
