Abstract: This publication described a method for loading the bearings of an intermediate roll (13,14) of a multi-roll calender (100) and a multi-roll calender (100). The multi-roll calender comprises one or more sets of rolls (10) in which in at least one set of rolls the centre shafts (C 14 , C 15 ) of at least two calender rolls form a nip plane (P), whereby for normal calendering a bottom roll (15) is loaded on the nip plane (P) by first load means, such as bottom cylinders (16). For partial nip run, in said at least one set of rolls (10) of the multi-roll calender (100) the centre shaft (C 15 ) of the bottom roll (15) is transferred, without detaching from the multi-roll calender (100), aside from the plane (V 14 ) passing via the centre shaft (C 14 ) of the intermediate roll (14) above the bottom roll (15), and the bottom roll (15) is loaded against the intermediate roll (14) above it by second load means (18) at an angle a of 15-25°, advantageously at an angle a of about 22°, in relation to the vertical plane.

Abstract translation: 该出版物描述了用于加载多辊压光机（100）和多辊压光机（100）的中间辊（13,14）的轴承的方法。 多辊压光机包括一组或多组辊子（10），其中在至少一组辊子中的中心轴（C _{14 ，C 15 ） 至少两个ca光辊形成一个n平面（P），由此对于正常ca光，底辊（15）通过诸如底部圆筒（16）的第一负载装置负载在该挟持平面（P）上。 对于部分压区运行，在多辊ca光机（100）的所述至少一组辊（10）中，下辊（15）的中心轴（C <15> 除了经过上述中间辊（14）的中心轴（14）的平面（14）之外，从多辊ca光机（100）分离 底辊（15）和底辊（15）通过第二载荷装置（18）以15-25°的角度α抵靠其上方的中间辊（14）加载，有利地以约22°的角度α °，相对于垂直平面。}

Abstract: The invention concerns a multi-nip calender (10), which comprises a frame formed by two frame parts (1,2) joined to each other or by one frame, in which frame are located two roll sets (3, 4), in which roll sets (3,4) calender rolls are located in stacks, in which multi-nip calender (10) the first roll set (3) in the web's (W) main direction of travel comprises at least two rolls, preferably two or three rolls (5, 6), and the second roll set (4) in the web's (W) main direction of travel comprises at least three calender rolls. An intermediate roll/intermediate rolls (7, 8) of the multi-nip calender's (10) second roll set (4) are adapted for transfer into the calender roll set of the first roll set (3) in order to provide two multi-nip roll sets (3, 4) in the multi-nip calender (10).
