Automatic basis sheet weight and moisture content measuring apparatus

Abstract

An apparatus for automatically measuring the basis weight and moisture content of a wet reconstituted tobacco web is disclosed. A specimen of the wet web is placed on a cutting surface of the apparatus and smoothed flat. A cutter is automatically positioned by a joy stick over the specimen and a test sequence is initiated. The cutter cuts out a sample of known area and transports the sample to a scale for weighing the sample in its wet and dry states. After the wet weight of the sample is entered into a computer, a heater dries out the sample while it remains on the scale. When the sample is dried, its dry weight is entered into the computer. Based on the wet and dry sample weights and the known sample area, the basis weight and moisture content of the reconstituted tobacco web is calculated by the computer. A disposal device removes the spent sample from the scale by suction and discards it into a waste receptacle.
