In its installed form, Cigarettes have a set air dilution and, if the smoker prefers, Rotate the rib 208 away from the proximal sleeve 207 and then remove the sleeve 20. 8 axially towards the charcoal end of the tobacco rod, thereby increasing the air permeability of the underlayment. With the chip, the paper 204 is exposed. This axial movement causes the air to filter to varying degrees. , thereby diluting the smoke and increasing the air dilution value of the cigarette. change. This axially slidable sleeve 208 is arranged in an a-end sleeve. The cigarette is retained by the tab 207 against being removed from the mouth end of the cigarette.

In an alternative embodiment, the plug wrap and tip are substantially air impermeable to the first layer of paper. There may be multiple apertures through them, and they exposed when the 208 is pulled apart and moved axially towards the charcoal end of the cigarette. It will be done.

The filter cigarette of the present invention is made of conventional cigarettes (22) The formation and cutting of the let rod and filter plug to length is conventional. Ma In addition, the filter plug should be aligned with the cigarette rod and the tip should be attached to the paper. -Covering means that the adhesive applicator applies the plug wrapper to the tobacco stick. The side bonding tip shall be adapted to be placed only on a portion of the first layer of paper. The rest is accomplished in the same way as for conventional cigarettes. For chips with chips, use the first layer of paper. The same machine is used to apply the tip to the end sleeve part of the second layer of paper. A glue applicator that is suitable for applying a band of glue. It can also be used to apply near.

For chipping, the rows of perforations in the second layer of paper are laser drilled, preferably prior to application. Any conventional method such as hole, electrostatic drilling, or mechanical drilling using a needle or knife. It can also be made by the following means. To make extremely small holes, laser - Preferably using a drilling device. In practice, the tipped paper will pass through the perforation zone. The laser beam is supplied with a laser beam that is focused horizontally across the width of the paper. The releasable sleeve of the second layer of chipped paper is exposed to the , to form the desired width of the part.

The power setting and focusing of the laser beam and the feeding speed of the paper with the chip are the 23rd Just release the paper along the tear-off line 210 shown in FIG. Selected by sea urchin.

The releasable sleeve is selected to leave enough force to cause the smoker to The paper with a wrapper can be easily pulled apart and hung unless the paper is torn between the holes.

Preferably, a laser device is used to make about 100 perforations in the paper along line 210 every inch. Make a hole.

Various modifications to the above-described embodiments are possible, for example, the first embodiment - This could be fixed by omitting the plug and creating a one-piece mouthpiece. second fruit The method is to attach the first and third bands to the paper without glue or other means. However, the second band could be attached or fixed to the plug wrapper. So In a second preferred embodiment, the apertures in the inner wrapper instead of the first band are Alternatively, make the first band again and make the corresponding holes in the outer layer of the paper with the tip. I can do sea urchin too.
