Abstract
For use on a form, fill and seal bagging machine a left side bag gripping member and a right side bag gripping member are located in association with a movable component of the bagging machine as, for instance, the head seal. The bag grippers contact and grip the left and right respective sides of a bag and spread these sides apart from one another just prior to formation of a cross seal on the bag by the head seal. This insures that the heat sealable film utilized on the machines is not puckered or pinched by the head seal therefore leading to a defective seal between the front and rear films forming the bag.
