Abstract

The ball game training equipment comprises two or more contra-rotating driven rollers in one plane at a distance apart such as to leave a gap between them which is at the most equal to the dia. of the ball to be thrown. Behind the first set of rollers are one or more second sets driven faster than them, the distance between them being such that on leaving the first set the ball nearly touches both. The rollers (1-4) each have a belt (51, 52) which is a clearance fit round it, and which can slip on its respective roller when a ball is inserted. Alternatively each belt can run round one roller in the first set and one in the second, on the same side of the ball.
