Abstract
The invention has to do with the modification of well known heat sealing bag machines to increase the production capability of the machines. The use of servo drives for selected components of the bag machine permits the reduction of film acceleration and consequential peak film velocity, thus allowing faster machine cycles at the same film acceleration and consequential film velocity.
