Problems solved by technology

The shorter the crimping time, the more pressure must be applied to ensure proper crimping of the sheet of material, which increases the risk of damaging the sheet during the crimping process

Embodiment Construction

[0082] For comparison purposes, in Figure 4 and 5 In , an apparatus 200 for crimping a sheet of material 70 and the crimped sheet of material are shown, realized according to the prior art. Figure 4 A partial view of two mutually facing crimping rolls 211 , 212 is shown, comprising interleaving corrugations 217 , 227 in side view (depicted exaggerated for clarity). Each roller 211 , 212 rotates about a respective axis 218 , 219 . Both rollers 211 , 221 have the same diameter 220 and width 221 . Each roll 211,212 contains a conventional ridge-groove pattern as corrugations 217,227. The corrugation or ridge-groove pattern 217, 227 is made up of circumferential ridges, each ridge defining a ridge amplitude. The ridges of the first and second rolls have the same amplitude and spacing. Furthermore, each ridge of the corrugations 217, 227 includes a top portion or tip 214, and a concave groove 215 is positioned between two adjacent ridges.

Abstract

The present invention relates to an apparatus and method for making a coiled sheet (70) of material for an aerosol-generating article. The method comprises the steps of feeding a substantially continuous sheet of material in a conveying direction (1) to a set of take-up rollers (11, 21), said set of take-up rollers comprising a A first roll (11) having a first plurality of ridges (17) for at least a portion of its width and a second roll having a second surface (22) of at least a portion of a material having a lower The hardness of the hardness of the material of the first surface. Additionally, the method includes feeding the substantially continuous sheet of material between the first roller and the second roller in the conveying direction of the sheet to feed the substantially continuous sheet The sheet is curled to form the curled sheet such that the corrugations of the first roll impart a plurality of curled corrugations to the substantially continuous sheet.

Description

technical field [0001] The present invention relates to a process for producing tobacco material in sheet form. In particular, the present invention relates to a process for producing sheet-like tobacco material for use in aerosol-generating articles, such as cigarettes or "heat-not-burn" products containing tobacco. Background technique [0002] Today, in the manufacture of tobacco products, homogenized tobacco material is used in addition to tobacco leaf. Such homogenized tobacco material is typically produced from tobacco plant parts less suitable for the production of filler tobacco, such as tobacco stems or dust. Typically, tobacco dust is produced as a by-product during the handling of tobacco leaves during manufacture. [0003] The most commonly used forms of homogenized tobacco material are reconstituted tobacco sheet and cast leaf. The process of forming a sheet of homogenized tobacco material typically includes the step of mixing tobacco dust with a binder to fo...
