Abstract
A method and apparatus for settling product in a servo-controlled vertical form, fill and seal machine where the product, when inserted into a partially-formed tubular bag, normally does not adequately settle without further action by the machine. The invention utilizes motion control of a servo motor to provide a settling action for product inside the partially-formed bag to introduce instability to cause settling in the bag at a very high frequency during continuous motion of the film and the film tube.
