the drive side end and the blank flange 42 or the assembly connection 43 on the front side end have to be exchanged in other respects the two long nip press rolls 25 in fig3 are identical it is noted that in both long nip press rolls 25 the axis of rotation 9a of the press shell 4 is displaced contrary to the direction of travel of the paper web 99 from the press plane e and the extension 18 of the press shoe 3 is located at its inlet side according to the invention the foregoing is made possible by groups of measures at each roll end there is a line 14 or 64 respectively opening into the pressure chamber 2 beneath the press shoe 3 all other internal supply and discharge lines 12 13 and 15 extend over the entire length of the long nip press roll 25 and are brought right up to both ends of the long nip press roll see fig2 and its internal lines 52 62 53 63 and 55 65 both ends also have coouplings e g coupling flanges 52 39 to 55 39 and 62 39 to 64 39 for external lines 112 113 114 and 115 if the long nip press roll 25 is installed in the second press 32 see fig3 then this corresponds to the representation in fig2 in this.
