ABSTRACT:
An applicator for curtain-pouring plastics or the like material of pourable consistency in which a base plate contains, inserted in a recess thereof, an applicator die block provided with a slit-shaped pouring orifice. On the base plate there are articulatedly mounted two half shells, forming an applicator head and adapted to be spread apart, and sealed with each other and with the base plate by means of sealing strips. Thus, there is no need for a re-adjustment of the orifice after each opening of the applicator head. Also, the width and/or length of the orifice can be readily changed by exchanging the applicator die block, and the entire structure is simple and of relatively low cost.
