Description
- The object of the invention is an apparatus and a method for manufacturing a roll of crimped filling material for rod-like articles.
- In the tobacco industry, various smoking articles filled with tobacco material and filter material are manufactured. Mouthpieces filled with a single type of filter material or with different types of materials may contain materials made from sections cut off from strips or sheets, the sections being suitably crimped. The crimping, depending on the type of material subjected to such process, may for example increase the absorption or the supporting surface of the material so as to give it sufficient volume to densely fill the wrapper and effectively filter the flowing smoke. In the crimped filling material formed into a cylindrical rod, a network of channels allowing the air to flow is formed. Furthermore, the crimping of the tobacco itself as filling material allows increasing the surface being in contact with the flowing air, which stimulates the release of aromatic substances into the flowing air.
- Apparatuses and methods for forming a crimped material used as a filling for rod-like articles of the tobacco industry are known in the prior art. For example, in the publication US2001709 there is disclosed a method of forming a continuous rod with a longitudinally crimped filter material filling. The crimping is carried out by means of a unit of crimping rollers forming an arrangement of longitudinal crimps facilitating the arrangement of the filling material in the wrapping material forming the continuous rod. Another example of the manufacture of longitudinally pressed rolls is disclosed in the publication US2164702A which discloses a system for crimping the filling material of rod-like articles of the tobacco industry wherein a continuous rod adapted for further cutting into individual rods is formed. The publication discloses a continuous process for forming a continuous rod using pressing in a direction longitudinal to the direction of forming the continuous rod.
- In solutions known from the prior art, longitudinal crimping of a continuous strand of a filling material is used, as a result of which an n-number of crimps is performed simultaneously, and the control of the crimping process as well as the subsequent forming of a roll from the crimped material are difficult. The present invention addresses the need to find a solution to facilitate the process of crimping and forming the crimped material into a cylindrical rod ready to be wrapped with a wrapper.
- The object of the invention is an apparatus for manufacturing a roll of crimped filling material for rod-like articles, comprising a unit for feeding a continuous strand of the filling material and a crimping unit for crimping the filling material. The apparatus according to the invention is characterised in that between the feeding unit for feeding the continuous strand of the filling material and the crimping unit there is a cutting unit for cutting the continuous strand of the filling material into sections, and in that the crimping unit is adapted to crimp a cut-off section of the filling material transversely to the direction of movement of the material section. The apparatus is further characterised by comprising a forming unit adapted to form the roll from the cut-off crimped section of the filling material in the form of a substantially cylindrical rod.
- Preferably, the apparatus is characterised in that the forming unit comprises a plurality of forming pockets.
- Preferably, the apparatus is characterised in that the forming pockets are provided with swinging elements being cylinder sectors situated parallel to the axis of the forming pocket.
- Preferably, the apparatus is characterised in that the forming pockets are placed on a drum conveyor.
- Preferably, the apparatus is characterised in that that the forming pocket has a movable bottom.
- Preferably, the apparatus is characterised in that the forming unit comprises a plurality of forming pockets on the drum conveyor, and further comprises a ring situated coaxially with the drum conveyor, the forming pocket being formed between the drum conveyor and the ring.
- Preferably, the apparatus is characterised by further comprising a guiding unit for inserting a section of the filling material into the forming pocket.
- Preferably, the apparatus is characterised by further comprising a feeding unit adapted to place a section of wrapping material into the pocket before forming a rod-like article from the cut-off section of crimped filling material and the section of the wrapping material.
- Preferably, the apparatus is characterised in that the wrapping material section is held in the pocket by means of a vacuum.
- Preferably, the apparatus is characterised by further comprising a guiding unit adapted to placing the cut-off section of the crimped filling material into the formed section of the wrapping material.
- Preferably, the apparatus is characterised in that the cutting apparatus is provided with rotary knives and a supporting roller.
- The object of the invention is also a method for manufacturing a roll of crimped filling material for rod-like articles wherein a continuous strand of the filling material is fed by means of a filling material feeding apparatus. The method according to the invention is characterised in that the filling material is cut into sections by means of a cutting unit for cutting the continuous strand of the filling material into sections, after which the cut-off sections of the filling material are crimped by means of a crimping unit. The method is also characterised in that a roll in the form of a substantially cylindrical rod is formed from the cut-off section of crimped filling material.
- Preferably, the method is characterised by comprising a step wherein sections of wrapping material are placed in the forming unit before forming the rod-like article from the cut-off section of crimped filling material. The method is further characterised in that after forming the rod-like article from the cut-off section of crimped filling material, the rod-like article is wrapped with the wrapping material section.
- Preferably, the method is characterised by comprising a step wherein the rod-like article formed from the cut-off section of crimped filling material is placed in a pre-formed wrapping material section.
- The solution according to the invention is an alternative to apparatuses and methods for crimping and forming individual rolls of filling material of the rod-like articles known from the prior art. In addition, the elimination of the process of forming a continuous rod allows to significantly reduce the space occupied by the apparatus.
