ASSEMBLY AND METHOD FOR POSITIONING ROLLS OF A MULTI-NIP CALENDER

摘要

The object of the invention is an arrangement and a method for positioning the rolls (1-12) of a multi-nip calender, comprising a top roll (1), a bottom roll (12) adapted to move, and at least one intermediate roll (2-11) of a set of intermediate rolls adapted to move between the top roll and the bottom roll, and loading members (15), such as loading cylinders, which are fastened, for example, to the body (22) of the calender and adapted to move the bottom roll (12). The position of at least one roll (1-12) is measured by a measuring device comprising a laser transmitter and a detector (24), one of which is fastened to the part adapted to move similarly with the roll (1-12) to be measured, and the other one to a stationary part.
