ABSTRACT:
A method for packaging flat articles, whereby the flat articles (1), when in a transport flow (3), are covered on both sides by a packaging material (2a,2b) and a welding beam (11) establishes cross-connections between subsequent articles (1) in an upper area (2a) and a lower area (2b) of the packaging material. Welding beams (11) are provided with at least one resilient hold-down element (12a,12b) each which brings the packaging material (2a,2b) to be processed into a defined position. The hold-down element (12a,12b) compresses the packaging material (2a,2b) before the welding beam contacts the packaging material (2a,2b) and executes a processing operation such as welding or pressing. The transport flow, in the area of processing, is transported by means of a support belt which exerts a force countering the forces exerted by the hold-down elements (12a,12b) and the welding beam (11).
