Abstract

The invention relates to a thermo-forming packaging machine and a method which are characterized in that the location of trays in a base film upstream of a sealing station is detected by a measuring system and that the sealing station is immediately subsequently positioned such as to allow a top film to be sealed with highest accuracy matching the tray and thereby to be able to compensate for irregularities and tolerances, for example, in the film feed, in a true-to-cycle manner.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This Application claims priority to European Application Number 12008109.6 filed Dec. 4, 2012 and European Application Number 13002228.8 filed Apr. 26, 2013, to Elmar Ehrmann and Christian Lau, currently pending, the entire disclosures of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to a thermo-forming packaging machine and a method for operating the thermo-forming packaging machine.BACKGROUND OF THE INVENTION[0003]A thermo-forming packaging machine is known from EP 0 569 933 A1 having work stations, for example, a forming, sealing and cutting station adjustable in the direction of production, which can be adjusted in dependence of the position of a print mark on a base film, where the print mark is detected by the forming station using a print mark sensor. The work stations have motorized adjustment drives with displacement measuring devices. Adjustable intervals between successive print ma...
