AUTOMATED POUCH FILLER ABSTRACT OF THE DISCLOSURE The performance of an automated pouch filler to fill institutional quantity sized bags of foodstuff can be improved by maintaining the sealing edge of the filled bag under tension during the sealing of the bag. Unwanted air can also be removed from the bag by utilization of a pair of squeeze bars to momentarily push excess air from the bag or by evacuating air from the bag through a vacuum tube in combination with soft sealing bars to temporarily close the bag during this evacuation. The top sealing edge is maintained under tension by use of a spring loaded clamp which attaches to one corner of the bag. The rejection rate of seal is dramatically decreased by providing a neck on the bag to form a partially presealed bag which is then sealed along a segment of the top edge of the bag after filling. The rejection rate is also dramatically decreased by sealing the top edge under tension. Laminated bags having an inner and outer bag can be utilized in the presealed configuration which particular advantage if the inner, free bag is tacked to the outer bag at the neck portion of the laminated bag, which inner and outer bags comprise the laminated bag at the neck portion of the laminated bag.
