- the third aspect it is possible to continuously manufacture raw material sheets of a predetermined length from roll-shaped raw material sheets, so that the raw material sheets can be continuously arranged on the case paper, and the productivity of the cartridge is improved. can be improved.
- a fourth aspect in any one of the first to third aspects, includes conveying the case paper in a first direction and placing the raw material sheet on the conveyed case paper.
- the raw material sheets can be continuously arranged on the case paper, it is possible to mass-produce cartridges.
- the gist of the fifth aspect is that, in the fourth aspect, the case paper is cut along a plane intersecting the first direction.
- a cartridge of any length can be formed.
- a sixth aspect is any one of the first to fifth aspects, comprising: forming half-cuts or debosses in the case paper; and folding the case paper along the half-cuts or debosses. This is the gist of it.
- the case material (case paper) can be easily folded along the half-cut or debossed edges when forming the case.
- a seventh aspect is the sixth aspect, wherein the raw material sheet is placed on the half-cut or debossed portion of the case paper, and the case paper and the raw material sheet are folded together along the half-cut or debossed portion.
- the gist is to include
- shifting of the folding position is suppressed, and the case paper and the raw material sheet can be folded at appropriate positions.
- the first end of the raw material sheet and the second end opposite to the first end is folded so that the raw material layers face each other, and after placing the raw material sheet on the case paper, the case paper is folded so that the base material layers of the raw material sheet face each other. and folding a sheet together with the case paper.
- the blade or the susceptor of the heating unit is arranged in the gap where the base material layers face each other to heat the raw material sheet, so that the raw material layer is heated without the blade or the susceptor coming into contact with the raw material layer. Efficient heating. As a result, the blade or susceptor is prevented from becoming dirty with the raw material layer, and the frequency of cleaning the heating blade or susceptor can be reduced.
- the gap between the raw material layers facing each other defines the air flow path, the aerosol generated from the raw material layer can pass through the gap. Thereby, the aerosol generated from the raw material layer can be efficiently delivered downstream.
- a ninth aspect is any one of the first aspect to the eighth aspect, wherein the case paper is coated with an adhesive, and the base layer is in contact with the adhesive applied to the case paper.
- the gist is to include placing the raw material sheet on a sheet of paper.
- the adhesion of the adhesive to the raw material layer is suppressed, and the influence of the adhesive on the taste can be suppressed.
