In the described method and apparatus a leader, distributed between two winding hubs of a magnetic tape cassette, is first completely would onto one hub by means of a first motor. Then, a second motor carries out a complete rewinding of the leader onto the second hub to enable an encoder to execute the counting of the overall length of the leader. Subsequently the first motor is operated again to rewind the leader onto the first hub. The encoder counts how much leader has been rewound on the first hub and causes the stoppage of the rewinding when the length of the rewound leader reaches a predetermined value. The invention arranges a leader so that it may be partly extracted from the cassette and then cut into two equal pieces which will be spliced to the opposite ends of magnetic tape.
