improve the adherence of the latter to the surface of the glass layer 2 the first bead 7 generally has an u shaped cross section thereby defining an inner tub shaped recess 10 with a first outer wall portion or leg 8 located adjacent to the edges 5 of the glass layer 2 and a second inner wall portion or leg 9 facing the central portion of the glass layer 2 the second inner wall portion 9 is higher than the first outer wall portion 8 the two wall portions or legs 8 and 9 delimit an elongate tub like recess 10 extending continuously along the edge of the window 1 the tub like recess 10 receives a second bead of adhesive material 11 which has essentially triangular as shown in the drawings or trapezoidal cross section thereby the arrangement is such that the second adhesive bead 11 on the one hand lies completely within the open tub like recess 10 which is delimited by the two wall portions or legs 8 and 9 respectively with other words the second bead 11 does not project over a plane running through the two upper edges of the two wall portions or legs 8 and 9 on the other hand the surface of the second bead 11 facing the open side of the tub like recess 10 ascends toward the higher wall portion or leg 9 of the first bead 7 preferably during depositing of the second bead 11 into the tub like recess 10 care should be taken that.
