Multi-segmented filters properties measuring device for tobacco processing industry, has laser light source forming line of electromagnetic radiation on filters, where extension of line is smaller than diameter of filters

摘要

The device has a laser light source (20) e.g. line laser, to radiate sections of multi-segmented filters or combination (10) of filter segments in a uniform manner. The laser light source forms a line (18) of laser beam on the multi-segmented filters or the combination of the segments, where the extension of the line transverse to a longitudinal axis (30) of the filters or the combination of the segments is smaller than a diameter (D) of the filters or the combination of the segments. An independent claim is also included for a method for measuring properties of multi-segmented filters or a combination of filter segments.
