Japanese Patent JP2003512909
Kind Code:
A
Abstract:
Improved process for the fabrication of laminated balls comprising forming by means of a rotor molding process a hollow sphere which configures the chamber or body of the ball, made of thermoplastic or thermostable material, mounting during that phase the female valve intended to the inflation of the ball, characterized by the steps of winding said previously inflated chamber to a desired diameter with a resistant yarn or filament; covering with panels of predetermined material and design the external face of the chamber which has been previously coated with adhesive; introducing the previously panel-covered chamber into a spherical mold at room temperature and during a predetermined time, providing said chamber with a sufficient air pressure in order to project the body of the chamber against the walls of the molds so as to obtain the adequate adherence of said panels to the chamber body and extracting the air from the ball thus fabricated and removing the ball from the corresponding molds.
