1. A machine for applying adhesive tape ties to gathered together necks of filled bags comprising:

  • an adhesive tape supply means for supplying adhesive tape having an adhesive and a nonadhesive side;

    manually moveable accommodation means including means for accommodating a gathered together neck of a bag and controlling translation movement of said neck through said machine;

    an adhesive tape support means for supporting said adhesive tape and including an upstream end and a downstream end, said upstream end being remote from said accommodation means and forming a space therewith, said downstream end being adjacent to said accommodation means;

    a slot in said support means adjacent said downstream end;

    paper tape supply means for supplying paper tape through said slot;

    a cutter;

    adhesive tape from said adhesive tape supply means following a path between said manually moveable accommodation means and said adhesive tape support means with said adhesive side of said adhesive tape facing said adhesive tape support means, said adhesive tape being in substantially line contact only with said downstream end of said adhesive tape support means;

    said paper tape being supplied through said slot into contact with said adhesive side of said adhesive tape;

    movement of said neck and said accommodating means causing the adhesive tape downstream from said neck to bow away from said accommodation means into said space and in contact with said upstream end of said adhesive tape support means, continued movement of said neck and said accommodation means forming an adhesive tape loop around said neck of said bag and causing further adhesive tape to be drawn from said supply means and past said support means with line contact only being established between said further adhesive tape and said adhesive tape support means whereby said bag and said accommodation means will continue to move freely as said tie is formed and said paper tape is applied to said tie, said cutter severing both said paper and said adhesive tape upon completion of said tie.
