The invention concerns a device for measuring, to a given tolerance, the width of a fiber pack passing between a pair of rollers mounted so that the nip can be adjusted. The invention calls for at least one of the pair of rollers to be made of a material with a low coefficient of thermal expansion, so that the thermal expansion of the pair of rollers when the measurement device is operating is less than the given tolerance on the width of the fiber pack. |
