A band screen (1) for installation across a channel (2) containing a flowing liquid (6) comprising an endless belt of screening panels (19), each provided with inwardly extending leading and trailing edge walls (26) and so attached to the belt as to be pivotable relative thereto. Cam plates (28) on the sides of the panels (19) slide along inner and outer guide tracks to control the panel orientations around the belt, causing the leading edge walls (26) to form upwardly facing steps on the upgoing side on the screen and to subsequently flatten to facilitate screening.
