  • Density control system for tea packaging apparatus
    Patent number: 4404787
    Abstract: A machine for packaging tea includes a rotary dispensing drum having rows of circumferentially spaced pockets into which tea flows by gravity through outlets at the bottom of a hopper. The tea is deposited in piles from the pockets on a web of packaging material which travels in contact with the periphery of the drum. The portion of the hopper containing the outlets is movable in relation to the drum so as to vary the effective area of the outlets and therefore the size of the deposited piles of tea.
