APPLYING LIQUID ADDITIVE FOAM TO TOBACCO FILLER

摘要

APPLYING LIQUID ADDITIVE FOAM TO TOBACCO FILLER In a cigarette-making machine a stream of tobacco passes from ecreteur 18 past splitter knife 63 and liquid additive foam is applied by nozzle 58. The moist tobacco stream is deposited by vacuum belt 12 onto conveyor belt 160 for passage through a microwave cavity 140 which dries and sets the additive foam. The tobacco is then delivered to garniture tape 22 for formation and wrapping of the tobacco rod. Alternatives described have the foam nozzle 58 upstream of trimmer knife 18 with drying and setting upstream or downstream of knife 18. Hot air may be used as an alternative to microwave heating.
