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 through folding in and sealing of a number of bottom wall panels. The bottom is pressed down and sealed whilst the blank is supported by a mandrel on a mandrel wheel. In order to avoid the transmission of the pressing-down and selaing forces to, and stressing of, the axle and bearing of the mandrel wheel an arrangement is proposed in accordance with the invention which is designed so that the compressive forces generated by means of the pressure devices (5) are absorbed by a tie rod (30) which connects the pressure application arrangement (14) with the axle (19) of the mandrel wheel (3), so that the forces are absorbed internally without stressing the mandrel wheel axle (19) or other surrounding elements. |
