High-quality rubber is mixed
with chemicals and into sheets

The sheets are heated and other
chemicals are added. The result
is a smooth paste.

The paste is cut into long strips which are turned into pallets by a totally integrated process, Each pellet becomes half a tennis ball.

The pallets are cooled before the next production stage. Random samples are tested in the lab.

The pellets are moulded into halves of tennis balls.

The halves are checked and smoothed before moving on.

A special rubber adhesive is applied to the edges.

The halves are cemented together with a natural rubber adhesive and then vulanised. The adhesive becomes as strong as the material it hold together.

The balls are flex-tested.

The balls are buffed and rubber adhesive is applied

Yet another precision control is performed.

Pre-cemented felt blanks are punched out.

The balls are coated with adhesive.

Each felt blank is manually or automatically applied.

The balls are vulcanized again.
