The invention concerns an apparatus for manufacturing of containers from blanks of a cardboard based material, said apparatus comprising: a container body forming unit configured to form a cylindrical container body from a substantially plane blank of a multilayer material comprising at least a supporting cardboard layer and a weldable layer; a welding unit configured to fasten an end closure to the container body, said welding unit comprising an inductive welding energy generator for melting of the weldable layer; and transporting means configured to transport a flow of body blanks to the container body forming unit, to transport a flow of container bodies from the container body forming unit to the welding unit, and to transport a flow of container bodies provided with end closures from the welding unit. The invention is characterized in that the transporting means comprises: a first movable gripping arrangement configured to grip at least two container bodies and move these container bodies simultaneously to the welding unit; and a transferring and positioning arrangement configured to transfer container bodies from the container body forming unit to the first movable gripping arrangement and to position the container bodies in a controlled manner to ensure that the first movable gripping arrangement can grip the at least two container bodies properly, wherein the welding unit is configured to simultaneously fasten an end closure to each of the at least two container bodies. The invention also concerns a method for operating an apparatus of the above type.

A packaging material is provided, comprising a core layer and one or more layers of a heat sealable material laminated thereto, and at least one carbon-based layer being configured to form a workpiece of an associated sealing system.

An anvil is provided in an ultrasonic sealing machine, in which vibration applying surfaces of a pair of horns and an abutment surface on an end face of the anvil cooperate with each other to bond a laminate. The abutment surface includes left and right welding surfaces which are disposed in the extending direction of the vibration applying surface and protrude toward the horns to face two vibration applying surfaces. The left and right welding surfaces each have an area per unit length in the extending direction, which continuously or step-wisely increases with an increase in distance from a center of the seal area, which is a region where the two vibration applying surfaces are adjacent to each other.
