Abstract (en)

The device (1) allows the opening of the hopper (20) of a curtain coater head (2) capable of dispensing, from a calibrated outlet slot (21), a curtain of ceramic glaze (S) onto ceramic tiles or slabs (4) in transit therebelow.The hopper (20) consists of two parts, the first of which is stationary (20F) whereas the second is movable (20M), the latter being connected to drive means (10) capable of imparting rectilinear horizontal movements thereto.The drive means (10) are of screw (100) and nut-screw (101) type, with a recirculating ball screw, and are driven by an electric motor (102) with encoder (103). Whenthe second movable part (20M) is brought closer to the first stationary part (20F), so that the aforementioned calibrated exit slot (21) is adjusted, an operating position (W) of said hopper (20) is defined.When the two parts (20F, 20M) are pushed apart, an open position (A) of the hopper (20) is configured, which allows the hopper to be washed with cleaning fluid under pressure.
