摘要： Tobacco smoke filters and methods and means for making same wherein the products have an elongated annular intermediate member overwrapped with a conventional plug wrap, with discrete inner plugs of a length shorter than the intermediate member and offering at least as much resistance to passage of smoke as the intermediate member, being secured within the intermediate member against axial displacement. The inner member may be formed of a filtration material, as is the intermediate member, or the inner member may be formed of a material which is non-permeable to smoke. Portions of the intermediate member may be crimped to embed them into the inner member thereby improving the engagement between these members. The inner member may be centrally positioned within the intermediate member to form cavities at each end of the filter or, alternatively, the inner member may be secured at one end of the intermediate member to provide only a single inner cavity. The smooth outer surface of the intermediate member enables the attachment of a conventional plug wrap without the need for an internal glue line. Means are disclosed for cutting an inner rod to form a multiplicity of inner plug members, and then axially spacing the inner members from each other by injecting jets of air or the like between adjacent inner members.

摘要： Tobacco smoke filter means, particularly for use with cigarettes and the like, having improved filtration efficiencies and/or reduced costs. One embodiment increases filtration efficiency by minimizing the crimped portion of the filtering material thereby maximizing the effective filtering area. Another embodiment reduces total weight of filtering material, and thereby costs of manufacture, while still producing high level filtration efficiency by utilizing a ''''double crimp'''' thereby forming an enclosed intermediate cavity means so that the smoke must pass through the filtering material twice.

摘要： A method and apparatus for making filter means of a type which is constructed to provide elongated, high surface area, cavities defined on opposite sides of a relatively thin wall formed of filtering material with only the ends of the filter means contacting an overwrapped outertube thereby presenting maximum available surface area of the material from which the products are formed to the smoke for filtration is disclosed. A tow of a suitable filtering material is passed through an air nozzle containing a mandrel centered therein, the tow thereby achieving a uniformly random, but tubular, configuration and then through a steam curing station followed by an air curing station. The formed rod is then again steam cured and passes to a crimping device which imparts a particular configuration thereto. The crimped rod is then again air cured, wrapped, and cut. In another embodiment, an additional material may be added by means either of a printing applicator device or a pulsating nozzle device.

摘要： A smoke filter is provided which is adapted to be affixed to one end of a tobacco rod. The smoke upon passing through the filter attains a very high velocity whereupon it impinges against a curved surface causing liquid and/or solid particles entrained in the high-velocity smoke to be deposited upon the impinged surface. The smoke, subsequent to impingement, follows a curved path prior to being discharged from the downstream end of the filter.

摘要： A method for forming successive spaced crimps in a tow of fibrous material by passing the tow along a path defined by an apparatus comprising a plurality of crimping wheels disposed around the path, each wheel including teeth having crimping surfaces and adjacent sealing surfaces which slide over one another during crimping to prevent material from being squeezed between the teeth thereby forming crimped sections with elongate edges which are substantially free of flashing connecting non-crimped sections. A second crimping step may be incorporated to form longitudinal grooves in alternate non-crimped sections. The rod-like member produced by these techniques may be overwrapped to provide pockets surrounding the crimped sections which may be filled with a smoke-modifying material, for example, activated charcoal particles. Discrete elements cut from the rod-like member may be used in cigarettes and the like such as in the production of filtered cigarettes.
摘要翻译：通过沿着由围绕该路径设置的包括多个卷边轮的设备限定的路径通过丝束来形成纤维材料丝束中的连续间隔的卷曲的方法，每个轮包括具有卷曲表面的齿和相邻的密封表面，另一个在卷曲期间以防止材料在齿之间被挤压，从而形成具有基本上没有闪烁连接非卷曲部分的细长边缘的卷曲部分。可以并入第二压接步骤以在交替的非卷曲部分中形成纵向凹槽。通过这些技术生产的杆状构件可以被包裹以提供围绕卷曲部分的袋，其可以填充有烟雾改性材料，例如活性炭颗粒。从棒状构件切下的离散元件可以用于香烟等，例如在生产过滤后的香烟中。

摘要： In order, when a cigarette is being smoked, to reduce, or even reverse, the tendency of the condensate-content to increase, a cigarette filter unit is proposed in which at least one partition having at least two areas of different porosities and made of a material which allows smoke to pass through it, is arranged between each two filter elements aligned axially with one another in the flow cross section of the filter unit. In this connection, a first partition area is designed in such a manner that its permeability decreases as the portion of tobacco associated with the cigarette filter unit is smoked, the tobacco smoke, passing through the said cigarette filter unit, flowing increasingly through the second partition area.

摘要： A method and apparatus for producing tobacco smoke filter having an improved tar/carbon monoxide ratio is disclosed. The filter is obtained by sealing off the center portion of the filter with an inner member which is impermeable to the passage of smoke, thus directing all of the smoke to the periphery of the filter. In one embodiment, the inner member is formed as a thin walled tube of a material such as polypropylene, with the tube being crimped to seal one end of the tube. The crimped tube is then overwrapped with a smoke permeable material.
