Abstract
1441090 Coating apparatus ILFORD Ltd 26 Sept 1973 [13 Oct 1972] 47349/72 Heading D1L Web coating apparatus comprising a hopper 44 having a liquid distribution chamber 47 and a distribution slot 45 from which the liquid is discharged onto a travelling web 41 is improved by providing in the chamber 47 a porous polyethylene tube 46 to which liquid is fed from a supply source and through the wall of which it is forced into the chamber 47, the distribution slot 45 being non-restrictive e.g. having a width of more than 0.5 mm. The improvements may be incorporated in an extrusion coating hopper (as illustrated), a curtain coating hopper [Fig. 4, (not shown)] or a slide coating hopper provided with a plurality of distribution slots, each with an associated distribution chamber and porous tube [Fig. 2 (not shown) ].
