Abstract: An apparatus for sealing packaging containers formed at least in part of a bondable material. The apparatus includes a first bonding unit and a second bonding unit which are fixedly disposed with mutual spacing on an endless conveyor. A device is provided for removing a covered container from the first bonding unit, after the container is provided with a first bonded seam therein by application of heat and pressure, and transferring it to the second bonding unit. This removing and transferring device is disposed on the common path of rotation of the two bonding units. The second bonding unit effects the application of a second bonded seam to the covered container.
