The effect of normal use on the surface of a football is determined by subjecting the ball to a simulated test where it is shot against a flat surface repeatedly and the effect of such impacts on its surface observed to evaluate its quality.
One of the methods employed for this simulation uses two cylindrical rollers to compress the ball. The ball, on coming out of the rollers, shoots forward at a high speed and strikes the test surface placed at a fixed distance. It is then guided back to the rollers and the action gets repeated automatically. The effect of these impacts on the surface is observed At the end of desired number of impacts to ascertain its quality.
The PROLIFIC Shooter Tester for footballs (roller type) consists of two rollers between which the ball is compressed, a steel plate placed at a known distance from the rollers against which the ball strikes, and a guiding arrangement to bring the ball back to the rollers.
The rollers are made of mild steel plates and have a lining of plastic sheet fixed to them to act as a friction surface. The distance between the rollers can be adjusted to enable balls of different diameters to be pinched between the rollers and get compressed, as also to give the desired percentage compression to the ball.
