Abstract

The invention relates to a thermo-forming packaging machine comprising a forming station, a loading station, a sealing station, a cutting station, and a film transport device with at least one clamp chain for transporting a lower film web in a direction of production. Unformed portions of the lower film web are movable in a horizontal film plane along the stations. A first chain guide device of an upper chain run of the clamp chain is provided in an upper chain guide plane in the region of the forming station, the sealing station, and the cutting station. A second chain guide device of the upper chain run of the clamp chain is provided in a lower chain guide plane in the region of the loading station. The lower chain guide plane is disposed lower than the upper chain guide plane.

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This Application claims priority to European Patent Application Number 15179067.2 filed Jul. 30, 2015, to Elmar Ehrmann and Christian Lau, currently pending, the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION

[0002] The invention relates to a thermo-forming packaging machine.BACKGROUND OF THE INVENTION

[0003] DE 10 2006 006 523 A1 discloses a thermo-forming packaging machine with several transport devices in the form of transport chains, also referred to as clamp chains. A lower film web is transported in a front portion by a first clamp chain up to a transfer region and there received by a second clamp chain and transported along a rear portion of the thermo-forming packaging machine up to a cutting station. The disadvantage of such a thermo-forming packaging machine is that the clamp chain in the loading region or in a loading station, respectively, can be fouled by products and expensive cleaning can ...
