  • Rod inspection method and apparatus
    Patent number: 11412777
    Abstract: A method of determining the density of an elongate rod of material as it travels in a longitudinal direction through an inspection zone of apparatus for determining the density of an elongate rod of material is disclosed. The method comprises: positioning an X-ray generator of said apparatus to transmit X-rays in a direction across the elongate rod and towards a detector of said apparatus, as the elongate rod travels in a longitudinal direction through said inspection zone of said apparatus; supplying a voltage to the X-ray generator of between 20 to 80 kV to transmit the X-rays at a predetermined intensity; detecting the intensity of the X-rays transmitted through the elongate rod using the detector, and determining a density of the elongate rod based on a comparison of the predetermined and detected intensities. A method of manufacturing tobacco industry products that includes the above inspection method is also disclosed, together with apparatus for determining the density of an elongate rod of material.
