An apparatus for producing laminated glass free of bubbles which includes a cylindrical metering bar interposed between upper and lower convergently-arranged, moving strips of glass which not only meters liquid adhesive but which serves as a doctor to fill any shallow depressions in the glass, thereby to establish perfectly planar adhesive surfaces which are subsequently brought into face contact at a nip using optimum pressure so that a full charge of adhesive is maintained in all of the shallow depressions. In a preferred embodiment the metering bar has metering grooves formed by closely spaced convolutions of wire and is rotated at a peripheral speed which is a small fraction of the speed of movement of the glass strips.
