<p>Method and device for contacting a band circulating at a high speed in a liquid in a deflection roller. The roller (4) has a contact surface with the band (3) comprising circonferential grooves (18). A gas is injected in the liquid (2) at the vicinity of the surface of the roller (5) so that the fluid entrained between the band (3) and the roller (4) is a compressible mixture of liquid and gas. In particular, if the liquid (2) is an electrolyte, the gas evolution may be obtained by means of electrodes (10, 11). A cap (12) enables to maintain the evolved gas at the vicinity of the contact surface of the roller. The invention applies in particular to the degreasing and cleaning of metal bands.</p> |
