  • Patent number: 4407305
    Abstract: A machine is shown for use in a tobacco stripping barn for stripping tobacco leaves from the stalk in three separate Grades. The machine has an elevated, elongated workbench or frame with three work stations side-by-side. Each work station comprises a pair of counter-rotating wheels that are adjustably biased into rolling contact with each other, and an adjustable guide member centered at one side of the wheels on which the tobacco stalk is supported as the stalk is passed over the top of the wheels, and the leaves are drawn down into the wheels and thus are pulled from the stalk to fall into a box or bin beneath the workbench. One of the wheels is motor-driven, and the other wheels are arranged in succession and biased as a group into rolling contact with said driven wheel.
