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.
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, wherein the method comprises:
-7. (canceled)
Apparatus for determining the density of an elongate rod of material as it travels in a longitudinal direction through an inspection zone of said apparatus, comprising:
Apparatus for simultaneously determining the density of each of two elongate rods of material travelling side-by-side in a longitudinal direction, the apparatus comprising an X-ray generator positioned to transmit X-rays of a predetermined intensity in a direction across the both elongate rods, a respective detector associated with each elongate rod, and a signal processor, each of said respective detectors being configured to independently detect the intensity of X-rays transmitted through an associated elongate rod and to send a signal indicative of said detection to said signal processor, the signal processor being configured to compare said detected intensity as determined by a respective detector with the predetermined intensity to determine the density of each rod.
A method of determining the density of each of two elongate rods of material as they travel side-by-side in a longitudinal direction, wherein the method includes:
-19. (canceled)
