Claim:
A method for producing a reclosable gusseted bag comprising the steps of: providing a first length of bag-making film as an upper web of the bag to be formed; providing a second length of bag-making film as a lower web of the bag to be formed; advancing said upper and lower webs in a bag-forming direction; sealing a section of a face of a first tubular length of gusset material to the lower web transverse to said bag-forming direction; sealing a section of a face of a second tubular length of gusset material to the lower web transverse to said bag-forming direction and at a bag width interval from said first length of gusset material; sealing a length of zipper in said bag-forming direction to said lower web and to an opposite face of each of said lengths of gusset material in alignment with the sections of said first and second lengths of gusset material sealed to said lower web; sealing said length of zipper in said bag-forming direction to said upper web in alignment with the sections of said first and second lengths of gusset material sealed to said lower web; sealing said upper and lower webs together and to said lengths of gusset material in said bag-forming direction to form a first end seal as the bottom of said reclosable gusseted bag; cutting said tubular lengths of gusset material, said length of zipper and said webs transverse to said bag-forming direction at said bag width interval; sealing said face of said lengths of gusset material at the transverse cut of each to said lower web; and sealing said opposite face of said lengths of gusset material at the transverse cut of each to said upper web.
