In an apparatus and a method for detecting impurities in a material, infrared rays or a plurality of specific wavelength components of the infrared rays are applied to a material (T) on a conveyor ( ), the respective reflection intensities of the specific wavelength components reflected by the material (T) are measured, the measured reflection intensities and the reflection intensities of specific wavelength components inherent to the material (T) are compared, and impurities in the material (T) are detected according to the result of the comparison.

In a cigarette manufacturing machine, a device for compressing and molding a filler stream includes a tongue, which defines a part of a compression-molding passage. The filler stream passes the compression-molding passage. The device further includes an ultrasonic vibration system for vibrating the tongue. The tongue functions as a horn of the ultrasonic vibration system.

A desk-top type infrared radiation moisture measuring apparatus is of a type in which the moisture in a specimen is exposed to a measurement light easily absorbed into water and to at least one reference light not noticeably absorbed into water and calculation is performed to determine the moisture in the specimen on the basis of both the measurement light and the reference light, reflected from the specimen. The apparatus comprises a turntable on which the specimen is placed and which is exposed to both the measurement light and the reference light from above at a portion away from the center thereof, and a drive source for driving the turntable into rotation. The measurement is carried out while the turntable is being rotated.
