Abstract
A method and apparatus for dosing and weighing "shag" tobacco comprising the steps of dosing an approximate quantity of tangled long fibre tobacco, which is less than the required quantity, and subsequently dosing disentangled long fibres to make up the approximate quantity to the required quantity of long fibres. Thus the quantity of short fibre tobacco added thereto to obtain the quantity nominally required per package can every time be equal.
Claims16
A method of dosing long fibre tobacco comprising the steps of providing an approximate quantity of tangled long fibres, said approximate quantity being less than the quantity required, plucking tufts from the tangled mass of long fibres with the aid of needles gradually emerging from holes in a tangentially moving surface, which needles are brought into contact with the mass as it is fed therepast after which the needles are retracted to set the tufts free, subsequently providing a sufficient quantity of disentangled long fibres and adding a predetermined quantity of short fibres to the dosed portions of long fibres to make up said approximate quantity to the required quantity.
An apparatus for dosing tobacco fibres from a tangled mass of long and short fibres comprising means for separating the short fibres from the tangled mass of long fibres, means for measuring but an approximate quantity from the tangled mass of long fibres, said approximate quantity being less than the quantity required and means for measuring out a sufficient quantity of disentangled long fibres to make up said approximate quantity to the required quantity.
An apparatus for dosing tobacco fibres from a tangled mass of long and short fibres, comprising means for separating the short fibres from the tangled mass of long fibres, means for plucking out tufts from said tangled mass of long fibres, means for compacting the tufts into a strand, means for disengaging a predetermined length of said strand, means for weighing this length of said strand, and means for measuring out a weight of disentangled long fibres in dependence upon the weight of the length of said strand.
