AI Technical Summary

Technical Problem

Existing methods struggle to efficiently distribute additives, such as aerosol-generating or flavoring substances, across sheet materials formed into rods without causing damage or waste, especially when the sheet materials are brittle, like those containing herbaceous materials.

Method used

A method involving a funnel-shaped confluence device where additives are dispensed onto the sheet material while it is being formed into a rod, utilizing a pipe with varying wall thickness and a friction-reducing coating to ensure uniform distribution and minimize material damage.

Benefits of technology

Achieves high additive concentration and efficient distribution across the sheet material, reducing waste and ensuring uniform application, even to the inner regions of the rod shape.
