Abstract

The ball game training equipment has two or more driven rollers rotating in opposite directions and spaced apart so as to leave a gap between equal to or less than the diameter of the ball to be projected. There are one or more additional sets of rollers (3, 4) at a distance behind the first set (1, 2) in the direction of travel of the ball (B), their peripheral speed being greater than that of the first set. The distance between the sets of rollers is such that, on leaving the first one, the ball nearly touches the second. The rollers on the same side of the ball in the two sets can be coupled together by endless belts, the distance between the sets being several times the ball diameter.
