Plywood is made by gluing several layers of wood veneers (thin sheets of wood) over each
other with grain pattern alternating at right angles in every subsequent layer.
During the plywood manufacturing process, the individual layers of veneers are first
obtained by rotary cutting log. For this timber logs are rotated about their longitudinal axis,
while a cutter peels the log at the set thickness.
Later on adhesive is spread on these veneers using a glue-spreader machine. After this the
layers are placed upon each other and hard pressed together using a hot-press machine.
The high temperature and pressure created by the machine, ensures that the adhesive fully
cures, thus firmly bonding the layers to each other.
