Abstract (en)
[origin: WO9001975A1] A ball-throwing device, in particular for tennis balls (5), comprises a ball magazine (2), a ball-ejecting device (3) and a delivery device (6), which delivers the balls (5) individually from the ball magazine (2) to the ball-ejecting device (3). The ball-ejecting device (3) projects each ball in function of one its pre-programmable shooting settings which govern the speed, spin and/or direction of projection of the ball (5). The variable frequency of delivery of the delivery device (6) is controlled in function of the shooting settings of the ball-ejecting device (3), each shooting setting used by the ball-ejecting device for projecting a ball (5) being associated with a time interval which determines the delivery of the next ball by the delivery device (6). The intervals between balls can therefore be adapted to the relevant ball characteristics as in a real game.
