Title:
APPARATUS AND METHOD FOR AUTOMATIC POSITIONING CIGARETTE PAPER AND MEASURING ITS PERMEABILITY
Document Type and Number:
WIPO Patent Application WO/2011/086527
Kind Code:
A1
Abstract:
The gas permeability of cigarette paper provided with portions or cross bands having, thanks to specific treatments such as impregnation with chemicals, painting, gluing films, or the like, specific chemical-physical properties, has to be measured. A machine for measuring the gas permeability of such portions or cross bands is provided with an apparatus for detecting such portions of cross bands and automatically placing them with a great accuracy in a permeability measuring station of the machine. The apparatus inspects the dielectric properties of the paper thanks to peculiar capacitive means and is able of a great sensitiveness and accuracy at placing the portions or bands in the permeability measuring station.
