  • An advantage of the disclosed solution is that ac curate quick thickness measurements can be provided. There is no need for any separate and complicated measuring sys tems in the machine, but instead the disclosed measuring means can be combined in connection with needed functional machine elements. Further, the structure of the measuring arrangement is simple, inexpensive and durable.
