devices 27 and 27 u2032 and 28 and 28 u2032 respectively seal between the axle journals and the bearing housings the bearing housings for the axle journals are movable horizontally so that the gap 14 between the rolls 9 and 10 can be changed as will be described with reference to fig3 the moving of the bearing housings and thereby of the axle journals of the bearing housings can take place individually and during the moving therefore the roll can be angled in relation to the bearing housing as shown in fig2 and the width of the gap 14 will then temporarily not be equal along the entire roll length as shown in fig2 this subjects the sealing devices 27 27 u2032 28 and 28 u2032 to large requirements fig3 shows the end wall 25 and two bearing housings 30 and 31 which are horizontally slidable along guide surfaces 32 and 33 in the end wall 25 as shown in fig4 when the suspension passes the gap 14 a line load is obtained on the rolls the line load can vary along the length of the gap and over time this is due to the fact that the properties of the suspension vary such as.
