Ball for game of table football - has inner sphere of one colour with relief pattern and outer plates of another colour positioned between reliefs

摘要

The ball is used in a game of table football and is moulded from plastic in two colours. The first colour is obtained by moulding two semi-spherical portions, these being provided with internal ribbing and assembled (7) by pegs in sockets to form one sphere. The outer surface of this inner sphere has a pentagonal relief pattern (1) distributed over it. The second colour is obtained by moulding another plastic layer on to the sphere. this second layer (5) fills the spaces between the relief patterns, level with their surface, the areas (2) being marked with dummy grooves (6) to imitate the same pentagonal pattern.
