Title:
METHOD AND APPARATUS FOR DETECTING INSUFFICIENTLY FILLED PART IN CONTINUOUS TOBACCO BODY
Document Type and Number:
Japanese Patent JPS5783271
Kind Code:
A
Abstract:
A cigarette rod making machine has a beta-ray detector which monitors the density of successive increments of the condensed filler in the continuously moving cigarette rod and changes the distance between the trimming device and the conveyor for the tobacco stream. The height of the tobacco stream (upstream or downstream of the trimming device) is monitored, and the thus obtained first signals are compared with second signals denoting the distance between the conveyor and the trimming device. The machine ejects those cigarettes whose fillers have caused the generation of first signals denoting that the corresponding portion of the stream contains less than a minimum acceptable quantity of tobacco. The height of successive increments of the stream can be monitored by an opto-electronic or capacitive detector or by a device which employs sound waves.
