Method and apparatus for automatically and continuously determining- the circumference and pressure drop of a tobacco smoke filter rod preferably composed of cellulose acetate fiber
Abstract
Abstract DISCLOSED IS A METHOD AND APPARATUS FOR AUTOMATICALLY AND CONTINUOUSLY MEASURING THE CIRCUMFERENCE AND PRESSURE DROP OF A TOBACCO SMOKE FILTER ROD PREFERABLY COMPOSED OF CELLULOSE ACETATE FIBER. IN THIS INVENTION A PLURALITY OF TOBACCO SMOKE FILTER RODS OF CELLULOSE ACETATE FIBER ARE STORED IN A STORAGE LOCATION AND SUBSEQUENTLY AUTOMATICALLY TRANSPORTED FROM THE STORAGE LOCATION TO A PRESSURE DROP MEASURING ZONE WHEREIN THE PRESSURE DROP OF THE ROD IS AUTOMATICALLY MEASURED. THE ROD IS THEN AUTOMATICALLY TRANSPORTED TO A CIRCUMFERENCE MEASURING ZONE WHEREIN THE CIRCUMFERENCE IS AUTOMATICALLY MEASURED. THE ROD IS THEN AUTOMATICALLY TRANSPORTED AWAY FROM THE CORCUMFERENCE MEASURING ZONE. THE METHOD AND APPARATUS OF THIS INVENTION ADVANTAGEOUSLY REDUCES THE TIME NECESSARY TO CONDUCT SIMILAR MEASUREMENTS USING CONVENTIONAL PRESSURE DROP AND CIRCUMFERENCE MEASURING EQUIPMENT THAT IS NOT AUTOMATIC AND CONTNUOUS IN CHARACTER.
