Abstract
Tobacco dust which develops in a machine or production line for the making of smokers' products is put to use in that it is gathered and agglomerated into particles having or exceeding a required size. Metered quantities of such particles are admitted into a stream of fragmentized tobacco leaves before the stream is draped into a web of cigarette paper or the like.
Claims21
A method of processing tobacco dust which develops in the course of the making of tobacco-containing products, comprising the steps of:
- gathering the dust;
- processing gathered dust into particles having sizes greater than the average size of dust;
- monitoring the sizes of the particles;
- and
- comminuting the particles having sizes greater than a predetermined size.
Apparatus for processing tobacco dust which develops in the course of the making of tobacco-containing products, comprising;
- means for gathering the dust;
- means for processing gathered dust into particles having sizes greater than the average size of dust;
- and
- means for comminuting at least the particles having sizes exceeding a predetermined size.
A machine for making smokers' products, comprising:
- means for establishing a supply of comminuted smokable material including tobacco dust;
- means for segregating the dust from the supply and for gathering the segregated dust into tobacco-containing particles, said gathering and segregating means including means for comminuting at least the tobacco-containing particles having sizes exceeding a predetermined size;
- means for converting the dedusted supply into smokers' products;
- and
- means for admitting the particles to the dedusted supply.
