A system and method for producing a medical bag with an HF welder that uses upper and lower dies each having a plurality of electrode lamellae arranged such that they are alternatingly polarized relative to adjacent lamellae and opposing lamellae. Interspersed dielectric materials may be used to impart contours onto the film material to produce a patterned bag.

Tool for HF welding, installation for producing a bag for medical purposes and method for operating such an installation

The invention relates to a method and an apparatus for separating foil layers in a foil processing line, the foil layers being caused to move relative to each other, and to a method and an apparatus for further processing the separated foils for manufacturing a product in which an insert is interposed between two foils.

Method and apparatus for separating foil layers as well as line for insert welding

The apparatus for connecting objects by means of a plastically deformable connecting body comprises a shaping punch ( ), a flow-restricting wall ( ) closely surrounding the shaping punch and a gas supply lead ( ) through which a gaseous medium can be introduced into the gap between the shaping punch ( ) and the flow-restricting means ( ). The shaping punch ( ) has a heating cartridge ( ) by means of which the lower end of the shaping punch can be heated. Provided on the outside of this shaping punch are heat-transfer ribs ( ) which are used to heat up the supplied, gaseous medium which emerges at the lower end of the flow-restricting means in order to produce a flow around a plastically deformable connecting body ( ), so that the latter is uniformly heated for the deforming process. The connecting body ( ) is also integrally formed on a part ( ) and reaches through a hole in a second part ( ) which is to be connected to the first part. The shaping punch ( ) is used to integrally form a rivet head ( ) on the connecting body ( ).
