Abstract:
1. A machine for making pouches from 2 sets of 2 webbed film materials and filling said pouches with a product comprising: a. a support structure on said machine for holding two pair of rolls of said film material and two sets of separate vertical fill tubes; b. an apparatus for gripping and unrolling film from each of said pair of rolls and for forming two separate continuous tubes, one tube from each pair of films around each said fill tubes; c. multiple product dispensers for inserting product into the pouches thorough said two set of fill tubes as they are being formed; d. a first station supporting 2 sets of separated pairs of opposing vertically aligned closable heat sealing bars for the formation of 2 sets of multiple longitudinal seals upon said 2 pair of film to join and bond said film together along the contact area of each of said pair of seals; e. two separate sets of multiple stationary blades each blade situated in a position such as to cut through and along said vertically sealed film along the path of the previously created side seal separating said seals and film into longitudinal tubes: f. a second station supporting two separate independent operable pairs of opposing closable pull wheels to advance said pair of film through machine; g. a third station supporting two separated pairs of opposing closable heat sealing members for the formation of transverse or horizontal seals at predetermined intervals upon said pairs of film to join and bond said films together along each of said seals; h. a fourth station supporting 2 separated pairs of knife blade assemblies for cutting across the centers of said transverse seals; and i. servo motors for driving each set of said vertical heat sealing bars, pull wheels, horizontal seal members and knife blades; j. control means for driving the servo motors so that a first group of vertical heat sealing bars, pull wheels, horizontal seal members and knife blades operate on a first film tube while holding the second group vertical heat sealing bars, pull wheels, horizontal seal members and knife blades inoperative on the second fill tube and then reversing the drive of said servo motors to reverse the operation of said two groups so that said first group is inoperative and said second group is operative on their respective film tubes.
