The intermediate pieces are nand between all built-in pieces inserted from over and under roller. It's awkward And time-consuming, because on the one hand matching spacers are placed inside the ax and on the other hand inserting and removing these distance pieces only from hoiiü can be done.

Time-consuming Icelandic work can, therefore, be given the task of designing the built-in sections assigned to the roller sets in such a rolling stand so that a spacer holder can be wiped over and lower roller during the process of the unit without the aid of additional spacers To solve this problem: According to the invention, it is proposed to design the chocks on the lower roll on their upper side and the chocks of the over roll on their underside in a stepped direction towards the roll axis and to allow these stages to fit into one another during operation, while prior to the change of position by lifting the nalzen from one another and limited shifting of the same relations v the lower step of the rolling chocks can be set down on the upper step of the rolling chocks ¹ 1st.

According to the invention, however, it is expedient according to the invention to let strip-like projections protrude into the otänuerfenster on both sides, in which hydraulic adjustment means are housed in a stationary manner, but not only to raise the roller with its liners for the purpose of changing the roller, but also for balancing uev overrolling can be used at the »alzbetrieb.

Conversely, of course, you can use the goods exchange device 13 also equilibrium sets sideways into the stud windows 1 of the roll stand 2 are pulled in »

By using graduated roller chocks according to the invention It is therefore possible to change the rollers while avoiding any manual work, e.g. by remote control of the adjusting spindles 7 and the roll changing device 13. This means that the roll change can be considerably be accelerated.

The four-high roll stand shown in FIG. 5 of the drawing represents a development of the roll stand according to Figures 1 to 4. Here, namely, the top roll 3 with its Lining pieces 5 not through the adjusting spindle «. 7 raised, if for the purpose of changing the rollers the lower stage lü the Chocks 5 placed on the upper step 11 of the chocks 6 should be. Rather, hydraulic adjustment means 14 are used for this purpose, such as those used, for example, in roll stands for balancing purposes of the top rollers can be used. This hydraulic Adjusting means 14 are fixedly housed in strip-like projections 15, which are inserted into the stud windows 1 on both sides protrude. This arrangement makes it possible to make a roll change without previously hoses that the hydraulic adjustment means with pressure medium supply, have to be uncoupled.
