Claim Text:
1. A process for forming and filling a pouch on a Vertical Form Fill Seal (VFFS) machine comprising the steps of: (1) providing a continuous tube of flexible and sealable film; (2) supplying the continuous tube with a predetermined flow-rate of flowable material fed from an external balance tank; wherein said balance tank comprises an inlet for said flowable material, at least one outlet for said flowable material, and at least one stand-pipe within said balance tank and over said at least one outlet, wherein said stand-pipe is flowably attached to said at least one outlet and filling the pouch; (3) sealing the pouch with heat sealing jaws used in conjunction with the VFFS machine; wherein the VFFS machine comprises an assembly for producing an oscillating force that actuates a heat sealing mechanism and comprises the following: wherein said top end is attached to said servo motor and said bottom end is positioned adjacent to said bottom of said frame; and wherein each said horizontal rails is slidably positioned in said horizontal channels attached to said opposing sides of said frame, and wherein said off-set slider mechanism of said shaft assembly is positioned in said rectangular-shaped opening of said pusher block; attached to said pusher block permitting the adjustment of pressure applied by the heat sealing mechanism; and whereby said servo motor, when actuated, drives said shaft assembly positioned in said pusher block, whereby said off-set slider mechanism moves said pusher block and provides a forward and backward motion to said pusher block sliding in said horizontal rails, and whereby said pusher block provides an oscillating force to said actuation means, thereby activating the heat sealing mechanism and sealing the flexible film forming the pouch and on deactivating said actuation means disengaging the heat sealing mechanism thereby allowing the pouch formed to advance through the VFFS machine.
