To-bac′co-plug ma-chine′.
One for adjusting and compacting the leaves into layers of the required form and thickness.
In
Fig. 6492, the tobacco is pressed between series of rollers into troughs running on flange-rollers.
A large wheel rotating in a transverse direction shifts the troughs on to a series of rollers rotating in the opposite direction, by which they are carried back to the starting end. An inclined knife removes the tobacco from the troughs when sufficiently pressed.
In patent No. 141,562, the tobacco-leaves are laid in a trough, which is placed between two adjustable guide-bars, the leaves resting upon a plate having slots, and beneath another plate having knives, which sink through the layer of tobacco into the said slots, dividing it into plugs.
A traversing roller, having shoulders to rest upon the sides of the box, gives the desired pressure, being placed in vertically movable bearings in a horizontally moving carriage.
