ABSTRACT:
Packing machines which manufacture packing containers of the so-called gable-top type from flexible packing laminate frequently handle prefabricated, tubular packing container blanks which are provided with a bottom section by folding in and sealing of a number of bottom wall panels. The bottom is pressed down and sealed while the blank is supported by a mandrel on a mandrel wheel.
In order to avoid the transmission of the pressing and sealing forces to, and stressing of, the axle and bearing of the mandrel wheel, an arrangement is proposed which is designed so that the compressive forces generated by the pressure devices are absorbed by a tie rod which connects the pressure application arrangement with the axle of the mandrel wheel, so that the forces are absorbed internally without stressing the mandrel wheel axle or other surrounding elements.
