An applicator for curtain-type pouring of pourable plastics or the like material, comprising two half shells having each an upper end and a lower end and constituting, when both in upright closed position, an applicator head having distributor channel means therein, a base plate having an elongated recess therein extending along a longitudinal recess axis, said two half shells being supported, at their lower ends, on said base plate, on opposite sides of said recess, and being articulatedly connected with said base plate for pivotal movement about axes extending parallel with said longitudinal recess axis, between said closed position, of said two half shells, and an open position in which said half shells are spread apart; and an applicator die block lodged firmly but removably in position in said recess of said base plate and having a slit-shaped orifice adapted for pouring molten plastics or the like material from said distributing channel means therethrough to emerge as a curtain, said slit-shaped orifice extending substantially along said longitudinal recess axis; said two half shells, when in closed position being at their lower ends in sealing contact with said applicator die block, and, when in open position, being spread apart far enough to permit removal or replacement of said applicator die block.
