The diagram shows that the process of manufacturing matches has several stages. The matchsticks
are first cut, prepared, dried and moved to a storage area. After that, they are dipped into several
chemicals and dried before being packaged.
In the first phase, a log of wood is placed in a peeler and rotated, while a flat blade peels a long, thin
sheet of wood, called veneer, from the outer surface of the log. The veneer proceeds to the chopper,
which cuts it into small sticks. These are then soaked in a vat of ammonium phosphate. Afterwards,
they are placed in a large, rotating drum. From there, the matches are dumped into a hopper and
blown through a metal duct to the storage area.
In the next stage, the sticks are moved from the storage area and they fall into a funnel-shaped
device which lines them up to be inserted into holes on a long, continuous, perforated steel belt.
As the belt moves along, the tips of the matches are dipped in a series of three tanks holding firstly
paraffin wax, then base chemicals and finally tip chemicals. Next, the belt loops up and down through
a drying area. In the final step of the process, the matches are packaged.
