Arrangement for a roller with a number of roller sections capable of being moved between a transport position and an operating position, which roller sections are capable of being supported by a main frame (3). The invention affords the possibility of achieving by simple means the simple and effective folding down and folding up of moving roller sections forming part of a roller. Arranged in such a way as to act between the main frame (3) and each roller side section is a mechanism (2) consisting of articulated arms, which mechanism comprises a pivoting swinging arm (13, 14) situated on each side (3A, 3B) of the main frame, which arm is connected on the one hand via a hydraulic lifting jack (17, 18) to an inner side frame section (9, 10) for the purpose of causing each side frame section (9, 10) to pivot relative to the main frame (3), and is connected on the other hand via drawing devices (23, 24) to an outer side frame section (11, 12) capable of pivoting relative to said inner side frame section (9, 10) for the purpose of causing the side frame sections (9-12) to pivot relative to one another. |
