Abstract
A rotary installation comprises a frame, a pair of rollers that define a pinch, mounting means for supporting the rollers on the frame, adjustment means for moving the mounting means and the rollers with respect to the frame as well as drive means for making the rollers rotate.

Installation fin making a cut, crease or relief and the like in a sheet of material, such as cardboard, comprising a frame (1), a pair of rollers (17, 18) that define a pinch (22) between them and the roller surface of which has relatively high surface portions and relatively low surface portions, such as cutting edges and/or edges for making a crease in the sheet of material when feeding it through the pinch, mounting means (14, 16;
- 42, 43) for supporting the rollers (17, 18) on the frame (1), adjustment means (9, 13;
- 193 23;
- 38, 41) for moving the mounting means (14, 16;
- 42, 43) and the rollers (17, 18) with respect to the frame as well as drive means for making the rollers rotate, wherein the frame (1) has a support member (3) that has a support side with respect to which the rollers (17, 18) are supported, which support side is parallel to the axis of the rollers (17, 18) and essentially extends the complete length of the rollers (17, 18), leaving a slit (24) free at the height of the pinch (22).
