Abstract (en)
[origin: WO9218209A1] Described is a tennis-ball throwing machine (1) in which tennis balls are conveyed by a feed device (2) into the cavity between two rollers (5, 6) mounted so that their axes are parallel, the balls being subsequently ejected by rotation of the rollers (5, 6). One roller (5) is mounted on a rocking lever which can be pivoted against the restoring force of a spring (8). The rocking-lever spindle (9) is mounted, parallel to the axes (3, 4) of the rollers (5, 6), on the pivoting carrier (10) for the rollers (5, 6).
