Embodiment Construction

[0042] exist figure 1 , the first and second tobacco sheets 3 , 4 are supplied to the splicing unit 2 from respective bobbins 30 , 40 . A first tobacco sheet 4 is used and passed through the splicing unit 2 in a substantially linear direction. The first tobacco sheet 4 is further conveyed to a tobacco sheet processing unit (not shown) arranged further downstream. Such a processing unit may eg be a crimping unit or a rod forming unit. The tobacco sheet 3 from the second bobbin 30 is guided by guide pulleys 22 and fed to the splicing unit 2 (here from below the tobacco sheet 4 in use) before the end of the tobacco sheet 4 on the bobbin 40 . The two tobacco sheets 3, 4 are arranged on top of each other and aligned on the support surface 21 of the splicing unit. It is then cut off by a cutting knife 20 at a cutting angle α. By cutting, a well-defined tail portion of the first tobacco sheet 3 and a well-defined head portion of the second tobacco sheet 4 are provided. After cut...

Abstract

The apparatus for combining tobacco sheets (3, 4) comprises a first shaft for carrying a first bobbin (30) of tobacco sheet (3) and a second shaft for carrying a second bobbin (40) of tobacco sheet (4). The apparatus also comprises a splicing unit (2) for combining an end portion of tobacco sheet from the first bobbin (30) to a head portion of tobacco sheet from the second bobbin. The splicing unit comprises a cutting device (20) for cutting the tobacco sheets such as to provide complementary cuts to the tobacco sheets (3) from the first bobbin and from the second bobbin (4), a dispensing device (23) for dispensing water to at least one of the tobacco sheets (3, 4), and a combining device (24) for applying force onto the tobacco sheets thereby producing a spliced tobacco sheet.

Description

technical field [0001] The present invention relates to apparatus and methods for combining tobacco sheets, in particular for the manufacture of smoking articles. Background technique [0002] In smoking articles with a heat source in which the tobacco is vaporized rather than combusted, the tobacco wrap may be made from tobacco sheet. The sheet material is very bulky and the size of the bobbins is limited. Therefore, at high production speeds, new bobbins must be loaded every few minutes or even more frequently. This is a time-consuming process, which can slow down production. In addition, some process steps in the tobacco sheet processing line do not allow conventional joining methods for two subsequent tobacco sheets. For example, a joining material such as a glue can affect the taste of the final product, while tap or enclosure angles are ineffective or add additional material to the sheet; usually to the point of flue forming or curling of, for example, the joined sh...
