摘要:
Apparatus for the separation of heavy and light particles from material which includes means for fluidising and agitating the material to cause heavy particles to sink from the acceptable material and comprising a deck adapted to receive material at a reception end and means for vibrating said deck to cause the material to move longitudinally along it to a discharge end, said deck having a number of longitudinally extending troughs separated by peaks and means for providing an upwardly directed air flow in the troughs characterised by means for causing two or more stratified material separation zones in each trough to classify the material two or more times.
摘要:
A machine and method for packaging smoking articles provides an essentially hermetic enclosure of a barrier material around a charge (2) of such articles in an open (incomplete) frame, by driving on the articles themselves to push them through a temporary wall (18) of the barrier material with the previous imposition on them of the open frame at a framing station (3). Preferably the driving is by means of an indexing conveyor which is stationary immediately before the collection of the charge from a hopper, during the imposition of the frame and immediately before pushing the frame and charge through the temporary wall.

A lightweight cigarette filter including a filter element containing filter material having a total Denier of less than 35,000 or a bulk density of less than 0.12 gcm⁻³ in which part of the volume of the filter is occupied by a space filler impervious to smoke flow therethrough and the bulk density of which is less than the bulk density of the equivalent amount of filter material which it replaces.

Apparatus for the separation of heavy and light particles from particulate material which includes means for fluidising and agitating the material to cause heavy particles to sink from the acceptable material and comprising a deck adapted to receive material at a reception end and means for vibrating said deck to cause the material to move longitudinally along it to a discharge end, said deck having a number of longitudinally extending troughs separated by peaks and providing an upwardly directed air flow in the troughs characterised by control means for causing the velocity of the upwardly directed fluidising air in each trough to initially increase to a point below the peaks and to then continue upwards at a reducing velocity.
