  • Patent number: 4215524
    Abstract: An apparatus for packaging a substance in closed bags formed from two continuous ribbons of a thin fragile material in which the ribbons are sealed to each other as they pass downwardly between first and second pairs of horizontal nipping rollers. A bag open at the top is produced from a portion of the ribbons by sealing and is filled with a predetermined amount of the substance to be packaged. The top of the bag is subsequently sealed to close the bag after the ribbons have advanced downwardly a predetermined distance. These operations take place sequentially on successive portions of the ribbons as they advance toward the second pair of nipping rollers, forming a series of sealed bags. At least one of the first pair of nipping rollers has a generally smooth annular concave portion extending between the end portions thereof, while at least one of the second pair of nipping rollers has a generally cylindrical portion of reduced diameter extending between its end portions.
