An industrial ironing machine comprising:
- an ironing cylinder;
- a flexible bed extending substantially around half of said ironing cylinder, said flexible bed being composed of two flexible stainless steel plates having a laser weld along a circumference of said steel plates and a series of welded spots obtained by a laser technique, wherein one of said flexible stainless steel plates, which engages the ironing cylinder in an operative position, has a thickness of between 3 and 5 mm, and a second one of said flexible stainless steel plates, which is situated in an operative position away from said ironing cylinder, has a thickness of between 0.80 and 1.20 mm;
- and
- means for keeping the flexible bed pressed against the ironing cylinder.

A method for manufacturing a bed to be used in combination with an ironing cylinder of an industrial ironing machine, said method comprising the steps of:
- providing two stainless steel plates one of said plates having a thickness of between 0.80 and 1.20 mm, and the other of said plates having a thickness of between 3 and 5 mm respectively;
- joining said plates along a circumference of said plates by a laser weld and further mutually connecting said plates by welded spots, which welded spots are also obtained by a laser technique;
- and
- finally deforming the plate of the smallest thickness by injection of water under pressure between said plates until a spacing of about 2 mm is realized between both plates.
