| 20110131935 | FORM-FILL-SEAL MACHINE - A form-fill-seal machine is adapted to manufacture a bag having a gusset section, and includes a conveying part, a plurality of splitters and an inward-folding member. The conveying part is configured and arranged to convey a tubular packaging material. The splitters extend along a conveyance direction of the tubular packaging material to contact with the tubular packaging material from an interior side. The inward-folding member has a pressing part including a plurality of contacting portions that are three-dimensionally arranged to generally correspond to a shape of the gusset section. The inward-folding member is configured and arranged to press the contacting portions of the pressing part from an external side of the tubular packaging material against an outer surface of a gusset formation area of the tubular packaging material located between the splitters to form the gusset section. | 06-09-2011 |
| 20120204514 | PACKAGING MACHINE - A packaging machine includes a pair of brushes that hold a tubular film (Fm) therebetween while rotating and impeding the advancement of packaged articles. Consequently, an elongated stream of packaged articles aggregate at the leading end of the pair of brushes. When the pair of brushes release the tubular film, the packaged articles are again conveyed in a more closely aggregated state than the aggregated state thereof when the advancement of the packaged articles was temporarily impeded. The rotational axis of each brush is also biased a predetermined distance from the central axis of a core thereof. Since the brushes swing in conjunction with the rotation thereof, small vibrations and large swings cause the gaps between packaged articles to be readily filled and reduce the space occupied by the packaged articles. As a result, the bag size can be reduced. | 08-16-2012 |
| 20120204515 | PACKAGING MACHINE - In a packaging machine, a pair of shutter members holds a tubular film therebetween and shake the tubular film. Articles on an upstream side of the shutter members within the tubular film therefore aggregate toward the side of the shutter members while the vibration of the shutter members causes the gaps between the packaged articles to be filled. Since the packaged articles aggregate by inertia due to the vibration, fragmentation thereof is less likely than in a case in which the packaged articles are compressed by direct contact. Merely by the movement of rollers on a waved surface of a shutter cam, the shutter members are shaken in accordance with the waved surface. | 08-16-2012 |
| 20120225763 | BAG-MAKING PACKAGING MACHINE - A bag-making packaging machine has a cylindrical part and a forming collar. The forming collar guides a sheet-shaped packaging material so that the packaging material wraps around the cylindrical part. The forming collar has a folded-back portion for changing a direction in which the packaging material advances to an approximately perpendicular direction. A cutout through which the thick-layered portion of the packaging material passes is formed in the folded-back portion. This reduces the amount of friction applied to the thick-layered portion when the packaging material passes by the folded-back portion of the forming collar. | 09-06-2012 |

| 20090094945 | Apparatus For Producing Bags With Three Dimensional Designs - The bag-making packaging machine 20 comprises a tubular former 23 having a former surface for aligning a packaging film 11, a pull-down mechanism 24, a vertical seal mechanism 21, a horizontal seal mechanism 22, and a molding apparatus 25 for molding three dimensional designs, in which the tubular former 23 has a molding surface 30 for molding the three dimensional designs at any position of the former surface, and the molding apparatus 25 is provided at the position opposite to the molding surface 30 of the former. As specific examples of the molding apparatus 25, a heater, a light irradiation apparatus, a mold, and pressing machine can be exemplified. When the molding apparatus 25 is the heater or the optical irradiation apparatus, a foamable ink is contained in the printing layer of the packaging film 11 to foam. When the molding apparatus 25 is the mold, the embossing is performed by further laminating the reinforcement sheet or the sheet for the three dimensional designs on the packaging film 11. And when the molding apparatus 25 is the pressing machine, the three dimensional sheet is laminated on the packaging film 11 beforehand. | 04-16-2009 |
| 20100037568 | BAG MAKING AND PACKAGING APPARATUS - A bag making and packaging apparatus is adapted to bend a film and to form a packaging bag. The bag making and packaging apparatus includes a former and a supporting member. The former is configured and arranged to form the film into a tubular shape. The supporting member removably supports the former. The supporting member is configured and arranged to allow movement of the former from a first position, in which a packaging operation is performed, to a second position, which is lower than the first position. | 02-18-2010 |
| 20100101193 | FORM-FILL-SEAL MACHINE - A form-fill-seal machine for manufacturing pouches of a plurality of types having different shapes includes a tubular part, a conveying part and a sealing part. The tubular part is replaceable according to a shape of the pouch to be manufactured. The conveying part is configured and arranged to convey tubular packaging material along the tubular part with an internal surface of the packaging material facing an external surface of the tubular part. A position of the conveying part with respect to the tubular part is selectively movable according to the shape of the pouch to be manufactured. The sealing part is configured and arranged to seal a prescribed position on the packaging material conveyed by the conveying part. | 04-29-2010 |
| 20110107729 | BAG MAKING AND PACKAGING MACHINE - A bag making and packaging machine includes a conveying unit, a transverse sealing mechanism, and a gusset forming mechanism. The conveying unit is configured and arranged to continuously convey a tubular packaging material. The transverse sealing mechanism has a pair of sealing jaws configured and arranged to revolvingly move while following annular loci to seal the tubular packaging material in a transverse direction with respect to a conveyance direction of the tubular packaging material. The gusset forming mechanism has a pair of folding members configured and arranged to be pressed against side portions of the tubular packaging material to form gussets in the side portions of the tubular packaging material while the folding members move along the conveyance direction of the tubular packaging material before the transverse sealing mechanism seals the tubular packaging material. | 05-12-2011 |
