Embodiment Construction
[0070] figure 1 It is a perspective view of a cutout part of the first base rod 1a. The first base rod 1a comprises a longitudinally extending substantially cylindrical core 2a of tobacco smoke filtering material. The substantially cylindrical core 2a is in the form of a cylindrical cellulose acetate plug having a length of 10 mm and a circumference of about 25 mm. The generally cylindrical core 2a is made from cellulose acetate tow that has been gathered and compressed into rod form by methods well known in the art. The first base rod 1a also comprises a first continuous extruded element 3a formed of extruded cellulose acetate extending longitudinally through the substantially cylindrical core 2a, enabling One end of the element 3a is seen at the first end 4a of the rod. The element 3a of continuous extruded cellulose acetate has an e-shaped cross-section and extends from one end to the other through the body of the rod 1a so that there is an e-shape which can be seen at ...

A method of producing a tobacco smoke filter or filter element, for example of the groove type, comprising the steps of: advancing a continuous flow of double filter rods longitudinally, wherein the double filter rods in the longitudinally advancing flow are spaced apart from one another longitudinally, each double filter rod comprises a longitudinally extending core of tobacco smoke filter material, and each double filter rod comprises a first base rod at a first end of the dual filter rod, a second base rod at a second end of the dual filter rod, and a third base rod positioned longitudinally between the first base rod and the second base rod; disposing a common wrap around the continuous flow of the double filter rods to provide a product rod comprising a plurality of wrapped double filter rods, the plurality of wrapped double filter rods being longitudinally spaced apart from each other within the product rod; cutting off the product rod at the half position of the third base rod; and / or cutting the product rod at a position half of the space between the double filter rods.
Description
[0001] This application is a divisional application of an application with an application date of August 3, 2015, an application number of 201510479274.8, and an invention name of "tobacco smoke filter". technical field [0002] The present invention relates to tobacco smoke filters and filter elements for tobacco products such as cigarettes. Background technique [0003] Recent developments in "formed filters"—that is, comprising a core of tobacco smoke filtering material extending longitudinally (eg, extending longitudinally through a core of tobacco smoke filtering material; extending longitudinally along a core of tobacco smoke filtering material) There is a growing commercial interest in the use of tobacco smoke filters of one or more elements, such as wire or extruded elements, which are visible at the mouth end of the filter. One advantage of shaped filters over standard tobacco smoke filters is that they provide a unique mouth-end appearance, which is useful for bran...
