In particular, the present invention relates to a method of forming a rod for use in the manufacture of Smoking products.

Prior art

Known rods with threads on the inside for use as filter rods. Examples of such terminals proposed in US 4281671 and US 2005/0255978. There are many problems associated with described their methods of manufacture of core products. For example, the method proposed in patent US 4281671, does not allow the manufacturer to securely place the thread just inside the terminals. So, if you want the thread passed along the Central axis of the rod, the method proposed in US 4281671, it is not possible to implement the invention with a certain degree of accuracy, which means that the thread is supposed to be offset from the center. This can result in uneven transfer of menthol, which in some cases causing stains or similar damage to the sheath, or covering, or wrapper, wrapped around filters, etc. the Problem method proposed in US 2005/0255978, is that it is not very suitable for flying the x flavorings, such as menthol, because the layer of flavors put on a solid substrate remote from the means for forming rod.

The present invention allows to overcome these problems. In this respect, the present invention provides a method of manufacturing a rod with a solid substrate, in which the solid substrate can be more accurately located inside the rod, and where the substrate contains an additive and / or coating additives.

Advantages

One of the key differences between the method (and apparatus) of the present invention and a method (and apparatus)described in US 4281671 and US 2005/0255978 is the initial contact between the source material and the material of the solid substrate. In the case described in patent US 4281671, this initial contact occurs remotely from the device-forming rod. According to the present invention the initial contact occurs in the forming device terminal. This provides many advantages. For example, after contacting the ability of a solid material substrate to move, for example, in the lateral direction, minimized, which means that workers can more accurately place the material inside the rod. In the case described in patent US 4281671, the material of the substrate can move easily in the lateral direction, resulting in an error of alignment, etc. in Addition, if the substrate material impregnated with a volatile flavoring agents such as menthol, according to the present invention can achieve a higher dispensing flavoring in the rod. This is because the flavor should not be too far relative to the distance on the versions done by the means, described in US 4281671 and US 2005/0255978 that it was concluded in the terminal. In addition, the present invention can be used chemically pure flavors, such as pure menthol, for this method; thus, minimizing the use of solvents as carriers, etc. for flavor. In some cases you can download the substrate material with a sufficient quantity of flavoring, thereby reducing or even eliminating the need to load the tobacco flavor. Other advantages will be obvious to a person skilled in this field from the following description.
