A stocker in a reel supply apparatus can support and deliver various kinds of reels having different outer peripheral diameters. It has a housing mounted on a reversely revolvable cylindrical body. At the both sides of the housing, reel supporting frames are provided in such a manner as to extend toward the opposite directions. Within the reel supporting frame structures, revolvable threaded shafts are disposed. Pushers are engaged with the revolvable threaded shafts in order to move along the supporting frame structures, respectively.

A tobacco manufacturing machine including a cover which covers the whole of the machine, a plurality of openable doors disposed in positions corresponding to various portions of the machine which require a manual correction by an operator, power sources for opening and closing those doors, a plurality of sensors attached to various portions of the machine for detecting states which require such a correction and a door opening and producing signals, and control means for logically processing the signals provided from those sensors and producing an operating signal for operating the power source corresponding to the door to be opened. Since the whole of the machine is covered, it is possible to greatly reduce noise during high-speed operation. Because the doors corresponding to various portions of the machine are opened automatically, the troublesome work involved in manual operation is eliminated.

A method and apparatus for inspecting cigarette paper of eventual cigarette bar unit, which permit further improvement of the precision of inspection, is provided. According to the method and the apparatus, the mean, variance and standard deviation are obtained statistically through a detected pressure signal, then transformation of their normal distribution into a standard normal distribution of N(0,1) where the mean with respect to the probability density function .PHI.(t) is 0 and variance with respect to thereto is 1, is obtained. And the estimation of population standard deviation with setting of a significance level is done with the value of t with respect to the probability determined solely by determining the probability in the normal distribution, thereby effecting a decision as to whether the inspected product is non-defective or defective.

A dilution monitoring system for filter cigarettes has pairs of pressure sensors provided individually for left- and right-hand manufactured filter cigarettes, a dilution processor card adapted to receive pressure signals from the pressure sensors through an A/D converter, and a server computer connected to the processor card by means of a communication line and including a CRT. The dilution processor card computes the respective dilutions of the individual filter cigarettes in accordance with the pressure signals, and stores the computation results in a RAM. Thereafter, the processor card obtains quality data, such as the average, frequency distribution, and standard deviation of the stored dilutions, for each group of the left- and right-hand filter cigarettes, also stores the quality data in the RAM. The server computer receives the quality data transmitted from the processor card, and displays them in the form of a graph or table on the CRT.

In a method of controlling the air permeability of the hole portion of chip paper in which holes are formed by a laser, the flow rate of permeating air from an air permeable portion of a dummy prepared in advance and the flow rate of permeating air from the hole portion are respectively converted to pressures. An output from the laser is controlled such that the pressure difference between the two pressures becomes zero. Then, an influence caused by variations in suction pressure can be prevented. Accordingly, the air permeability can be detected without being influenced by variations in suction pressure.

In an apparatus for forming micro-holes on a cigarette, a laser beam is divided into first and second laser beams by a two-dividing mirror. Parts of the laser beams are detected by photo detectors, respectively and the other parts of the laser beams are guided to polyhedron mirrors through first and second optical paths and divided into segment beams by the mirrors, respectively. The segments beams are focused on the corresponding cigarette so that micro-holes are formed on the cigarette. The cigarette is transferred to a dilution detection stage and the dilution is detected in mode, detection signals from the photodetector are processed and a first driving signal is generated. Thus, the two-dividing mirror is driver by a driving mechanism in accordance with the first driving signal so that the intensity of the laser beams guided in the first and second optical paths are maintained in substantially equal level. In an stable driving mode, a second driving signal which is determined in accordance with the detected dilution is applied to the driving mechanism in stead of the first driving signal so that the two-dividing mirror is a driven in accordance with the second driving signal.
