Abstract
A device for sealing two-piece capsules has a capsule carrier and a capsule holder which are movable relative to one another for the purpose of attaching a cap to a capsule body. In order to bond a cap firmly and tightly to the body of a capsule, the device has a nozzle for applying a viscose sealing material to the inside of the cap. To prevent an excess of sealing material from being applied to the cap, the nozzle is provided with a vacuum mechanism in the form of an annular channel by means of which excess sealing material is removed during the application.
