<p>The appts. for football practice or training is shaped like a goal at football with goal frame and a net behind it. The net is made as a vertical net surface (4) located behind the goal frame (1, 2) and projecting from it slightly at the side and at the top. A rebound wall (5) is located at a distance behind the net surface which is subdivided into a number of target surfaces which are sensitised electronically by a ball hitting them. The distance between the door frame and the net surface is smaller than the diameter of the ball, and the distance between the rebound surface and the net surface can be adjusted.</p> |
