the view from above in fig2 these two stages 07 are arranged in a straight line with the roll changers 01 and the printing tower 02 in the extension of this straight line it is possible to arrange a further printing tower 02 u2032 and further roll changers 01 u2032 which are represented in dashed lines in fig1 and 2 for its supply webs 04 u2032 06 u2032 imprinted in this further printing tower 02 u2032 are also conducted to turning and mixing stages which constitute a stack with the stages 07 a longitudinal cutting device 08 such as for example in the form of two traction rollers which rotate in contact with each other between which respective webs 04 06 are passed and on one of which there is situated a rotating blade is located between the printing tower 02 and the turning and mixing stage 07 if required the longitudinal cutting device 08 can be moved away from the webs 04 06 so that it lets the webs 04 06 to pass through the longitudinal cutting device 08 uncut each turning and mixing stage 07 contains three turning or deflection bars 09 11 which are arranged at an angle of 45.
