Determining the orientation of at least one object and method for relatively orienting rollers

A device for determining an alignment of at least one object, comprising:

• at least one measuring body that reflects electromagnetic radiation and is bringable into physical contact with a surface of the at least one object to determine the alignment;
• at least one measuring carriage that is movable along the at least one object during the determination of the alignment and has a sliding surface physically contactable contact with the at least one object;
• at least one holding unit that holds the at least one measuring body and is connected to the at least one measuring carriage so as to be pivotable between a maximum position, in which the at least one measuring body at least partially protrudes beyond the sliding surface on an object side, and a minimum position, in which the at least one measuring body does not protrude beyond the sliding surface on the object side;
• and
• at least one restoring device configured to apply a force to the at least one holding unit in a direction of the maximum position.
