ABSTRACT:
In a tennis-ball throwing device, tennis balls are conveyed by a feed device into a cavity between two rollers mounted so that their axes are parallel, the balls being subsequently ejected by rotation of the rollers. One roller is mounted on a rocking lever that can be pivoted against the restoring force of a spring. A spindle or axis of the rocking lever is mounted parallel to the axes of the rollers on a pivoting carrier for the rollers.
