Abstract: The reflector mark (2), consisting exclusively of a metal layer, at the beginning and end of a magnetic tape (1) is transferred to the said tape with the aid of a carrier strip (6). For this purpose, the metal layer provided with adhesive (4) is pressed on to the magnetic tape by means of the carrier strip, on which the said layer is held by a coupling agent layer (7), at a temperature at which the metal layer detaches itself from the coupling agent and the adhesive is activated.

Abstract: For cleaning or smoothing the surface of a material web (2), the latter is passed over at least one blade (4), the web being pressed against the blade edge (10) by means of a vacuum. The opening (9) of a vacuum chamber (8) formed next to the blade (4) is adjustable with respect to the blade edge (10), so that different flows and forces can be set.
