Abstract
A method of measuring fiber while being processed by a fiber processing machine, includes the following steps: measuring the length of fiber at an inlet of the fiber processing machine; measuring the length of fiber at an outlet of the fiber processing machine; and forming a difference between the values measured at the inlet and the values measured at the outlet for determining an extent of shortening to which the fiber is subjected as the fiber passes through the fiber processing machine.
