摘要： A calender and an arrangement for mounting calender rolls, the calender comprising at least two calender nips (1, 2) formed by at least two stacked rolls (11–14). The rolls are have bearing housings (3–6) by means of which the rolls (11–14) are stacked into roll pairs forming the calender nips (1, 2), and means (31, 32) connecting the bearing housings (3, 4 and 4, 5) of the rolls pairs with each other. At least two successive calender nips (1, 2) are arranged so that in the successive nips the mutual distance between the longitudinal axes of the lower rolls (12, 14) is smaller than the corresponding mutual distance between the respective upper rolls (11, 13) of the nips, whereby the disposition of the rolls (11–14) forms a V-shaped angle as seen from the end of the calender machinery and thus forms an operating area between the nips for changing the rolls. The rolls are combined into nips advantageously using heatable pull rods inserted through the bearing housings.
摘要翻译：一种压延机和用于安装压延辊的装置，所述压延机包括由至少两个堆叠辊（11-14）形成的至少两个压延辊（1,2）。辊具有轴承座（3-6），通过辊轴（11-14）将轧辊（11-14）堆叠成形成压延辊（1,2）的辊对，以及连接轴承座（3）的装置（31,32），4和4,5）彼此成对。至少两个连续的压光辊（1,2）被布置成使得在连续的压区中，下辊（12,14）的纵向轴线之间的相互距离小于相应的上辊（11， 13），由此轧辊（11-14）的布置形成从压光机械的端部观察到的V形角度，并且因此在用于改变轧辊的辊隙之间形成操作区域。辊可以有利地使用插入轴承座的可加热拉杆组合在一起。

摘要： A calender is disclosed comprising at least two calender nips formed by at least two stacked rolls (8, 9; 14, 15) so disposed mutually in regard to each other that in the successive pairs of rolls the distance between the center axes of the lower rolls (8, 14) of the roll pairs is smaller than the distance between the center axes of the respective upper rolls (9, 15), whereby the rolls (8, 9; 14, 15) as seen from their ends are staggered in a Vangled configuration so as to leave space therebetween for changing the rolls. The invention provides a very compact calender construction by way of having the pairs of rolls (8, 9; 14, 15) staggered in regard to the vertical plane so as to locate the rolls at different height levels.
摘要翻译：公开了一种压光机，包括由至少两个堆叠的辊（8,9; 14,15）形成的至少两个压延辊，所述至少两个堆叠的辊（8,9; 14,15）相对于彼此彼此相互设置，在相继的成对辊中，下部辊的中心轴线之间的距离辊对的辊（8,14）小于各个上辊（9,15）的中心轴线之间的距离，从而从其端部看到的辊（8,9; 14,15）交错在为了在辊之间留出空间以便改变辊子的一种波纹构造。本发明通过使成对的辊（8,9; 14,15）相对于垂直平面交错提供非常紧凑的压延机结构，以便将辊定位在不同的高度水平。
