Abstract
A wrapping paper inspection apparatus includes a nozzle arranged in a wrapping-paper discharge path, in which wrapping paper is wound and continuously discharged, for wetting one side of the wrapping paper with a liquid; an image pickup section for irradiating light to the wrapping paper wetted with the liquid by the nozzle, detecting light transmitted through or reflected from the wrapping paper, and generating an image signal; and a wrapping paper inspection section for determining defects in wrapping paper portions applied or affixed with a low flame spread material, from the image signal generated by the image pickup section, to thereby inspect such defects easily and reliably. This inspection apparatus can be mounted to a tobacco wrapping machine.
