We are a leading Manufacturer of liquid sampling cup with rod, rotary bottle washing machine, bottle drying oven, filter press machine, industrial emulsifier machine and volumetric liquid filling machine from Delhi, India. In accordance with the present invention, therefore, I have found that if the pressure drop and circumference of the cigarette filter rod are measured simultaneously, then one knows at what circumference the filter rod pressure drop was read while being compressed inside an elastic sleeve or rubber diaphragm.
The machine is comprised of two main units, a tow opening unit 10 and a rod forming unit 12. In the opening unit 10, a web 14 of crimped tow material from a bale (not shown) first passes through an initial spreader 16 which flattens the web into a generally planar shape.
Conclusions This study indicates that cigarette designers at Philip Morris, British-American Tobacco, Lorillard and other companies believed for mono filter rod a time that they might be able to reduce some of the most dangerous substances in mainstream smoke through advanced engineering of filter tips.
My invention is directed to a method by which substantially true pressure drop of nonwrapped and soft wrapped cigarette filter rods may be determined when the circumference of such cigarette filter rods is being compressed for such determination by a total encapsulation procedure of the entire filter rod, and to an apparatus for practicing the method.
2, thereby causing the tubular rubber diaphragm or elastic sleeve 14 to become expanded, and then sequenced to pull a vacuum upon the outlet port of fitting 52 so as to cause the cigarette filter rod to be moved into seated position against seat 44 of the back member 42. The vacuum upon the sealed chamber is then sequenced for release, and as a consequence the elastic sleeve collapses around the cigarette filter rod to sealingly adhere to the circumferential surface of the filter rod and thus encapsulate it. The elastic sleeve now forms a substitute profile for the main profile of the cigarette filter rod and serves as a reference surface to be measured.
Although cigarette engineers have known for decades that filters are ineffective in reducing the health consequences of smoking, the early history of this research and development agenda might be separated from the misleading marketing of filtered cigarettes that has persisted for nearly 60 years.
Nonwrapped cigarette filter rods, such as nonwrapped cellulose acetate filter rods (NWA) present a different problem in accurately measuring pressure drop because without the paperwrap the elastic sleeve or rubber diaphragm actually compresses the wrapless filter and thus causes an overstatement of the pressure drop.
The axial inner end of the annular member is reduced in diameter to essentially the diameter of a cigarette filter rod to be tested, so as to prevent the end of the filter rod from being crushed or pinched by the elastic sleeve, and provides in turn an annular outer surface 32 around which one end or the forward end of the elastic sleeve 14 is sealingly connected, as by means of a rubber -ring 34. The opposite or rearward end of the elastic sleeve 14 is sealingly connected via -rings 36,38 to and around a tapered outer surface 40 of the back member 42. The forward end of the back member defines a seat 44 against which a filter rod is to abut when in seated position, and has a diameter essentially the same as that of the cigarette filter rod to be tested to prevent that end of the filter rod from being crushed or rounded by the elastic sleeve.
The utility model belongs to the tobacco product technological art, more particularly relates to a cigarette filter element featured of the structure, comprising a mouth bar filter element, a mouth bar paper pipe coiling layer and a water loose paper pipe layer, wherein the mouth bar paper pipe coiling layer embraces the mouth bar filter element, the water loose paper pipe layer embraces the mouth bar paper pipe coiling layer, a hollowed part is equipped between two filter elements, and at least one portion of the mouth bar filter element is a hollowed part.
Yuri Gagarin Plc offers a wide range of mono-acetate and combined cigarette filters which can be of different length, diameter, ventilation, pressure drop and segmentation according to customer requirements. However, Eastman Kodak and Celanese dominate the patent record during these years, especially regarding large-scale production designs for filtered cigarettes.
