for instance at the start up of the calendering surface at the start the nip gap is not closed but the roll 22 has been moved out of contact with the nip 1 before moving the heated counter roll 22 into the nip the drive arrangement 44 of the enclosed shoe roll 10 is activated to accelerate the first end wall 24 via transmissions the rotation of the end wall causes the inner first cog wheel 46 to rotate and subsequently the drive shaft 48 the drive shaft transmits the rotation to the second end wall 26 via the second inner cog wheel 56 the both end walls are thus accelerated and rotate at the same speed until a desired peripheral speed is obtained which is normally equal to the speed of the fibrous web the nip is closed by activating the hydraulic piston 94 to pivot the lever 95 and thereby moving the counter roll 22 into the nip and subsequently the load shoe 18 is urged against the heated roll 22 by its actuators 20 once the calender functions in the desired manner the drive arrangement of the enclosed shoe roll can be deactivated and the press roll driven in a conventional manner by friction within the nip 1 in fig2 b there is shown an alternative embodiment of the drive arrangement for an enclosed shoe roll this embodiment uses friction for the transmission of rotational forces fig2 b also shows.
