Tennis ball regeneration machine - has container with base plate, plexiglass(rtm) cylinder cover, manipulator with handle and bar stopper to refill b all with compressed gas

摘要

The machine incorporates a container (1) for each ball, consisting of a base-plate (6) on which is a plexi-glass cylinder (7) on which is a cover (8) pierced by a manipulator (12). The base-plate, cylinder and cover are held together by axially parallel tension-screws (10) outside the plexiglass cylinder. The ball-holder's interior forms an excess pressure chamber (3) closed by a compressed gas pipe with locking-valve (4). The manipulator operated from outside by a handle (13) and adjusting bar (14) going through the lid inserts and fastens a stopper (16) into the ball's filler-hole (2'). USE/ADVANTAGE - Tennis balls which have a rubber-type casing and compressed gas filling and which have lost their elasticity. Does not need puncturing needles.
