There may be cases where the high weight of a product to be packaged affects the quality of the bag seal. In this case it is possible to install an heavy products conveyor under the machine, which has the function of supporting the bag when products of a certain weight are introduced to avoid the breaking of the lower seal and a low quality of the upper seal. 

This carpet can be manually adjusted with pneumatic step or with motorized height adjustment.

In the last part of the video example you can see a pneumatic step belt that is adjusted by an employee and that supports the bag in which the pieces to be packed are inserted, to then transport the finished product to the evacuation point.
