Abstract:
A device for bonding a first plate-shaped object to a second plate-shaped object by means of an adhesive, comprising: a first holder with a supporting surface for the first object, a second holder with a supporting surface for than second object, means for applying the adhesive to at least one side of the first or second object, a displacement unit by means of which the two holders with the supporting surfaces can be moved towards each other, and a pressure unit by means of which the supporting surfaces of both holders can be pressed against each other, a rotation unit by means of which both holders can be rotated at equal rotational velocities, and wherein the spreading of the adhesive is controlled during a bonding operation by varying at least one of the rotational velocity of the first and second holders as a function of time and the approach speed at which the first and second holders are moved towards each other.
