ABSTRACT:
An apparatus for binding page edges with heat includes a cover portion which has the approximate shape of a truncated pyramid and which has a longitudinal opening which is at least partially closed by a pivotably mounted wall is provided. The apparatus includes a longitudinal heat-conducting element of a length generally corresponding to the length of the page edges to be bound. The apparatus further includes an actuator or starting signal to activate an electrical switch when the edges to be bound are contacted with the heating element, indicating that the heating process has started and continues to heat depending on the thickness of the leaves to be bound. The electrical switch is then disconnected, thereby generating a signal indicating the completion of the heating and binding process.
