20090005228 | Method and Device for Manufacturing Bag with Clamping Device | 01-01-2009 |
20090050254 | DEVICE AND METHOD FOR MANUFACTURING BAG WITH CHUCK TAPE - A manufacturing device for manufacturing a reclosable-tape-having bag manufactures a reclosable-tape-having bag in which a reclosable tape is mounted on an inner surface of a bag body | 02-26-2009 |
20090119889 | INTERLOCK TOOL, BAG MAKING USE THEREOF AND PROCESS FOR PRODUCING THEM - A zipper in which a male member having a male interlocking section and a female member having a female interlocking section that fits with the male interlocking section are peelable and re-fittable is provided. The male member and the female member are formed by different resins, and at least the male interlocking section and the female interlocking section are peelably adhered or contacted with each other with substantially no gap. | 05-14-2009 |

20100074562 | EASILY TEARABLE FASTENER TAPE, METHOD OF PRODUCING THE FASTENER TAPE, PACKAGING BAG WITH EASILY TEARABLE FASTENER TAPE, AND DEVICE AND METHOD FOR PRODUCING THE PACKAGING BAG - A belt-shaped base of a male member of a zipper tape attached to an inner surface of a bag body includes: a main body on which an engagement portion is provided; a first projecting portion provided on an opening-side of the main body; a thin portion connected to an opening-side of the first projecting portion; and a second projecting portion connected to an opening-side of the thin portion. A belt-shaped base of a female member includes: a main body; a first projecting portion; a thin portion; and a second projecting portion. When the zipper tape is fused onto the bag body, a space is provided between the thin portions and a film of the bag body. | 03-25-2010 |
20100210439 | DEVICE FOR CUTTING PACKING BAG, DEVICE FOR PRODUCING PACKING BAG AND METHOD FOR PRODUCING PACKING BAG - A cutter includes a male blade, a female blade, an advancement and retraction controller and a suction device. The male blade includes: a linear cutting portion linearly shaped with a predetermined thickness in a center part; a rounded cutting portion where a radius having a substantially arc shape in planar view is continuously formed from the linear cutting portion; and an end provided adjacent to the rounded cutting portion. The female blade has a fitting portion that is a hole conforming to the profile of the male blade in planar view and to which the male blade is fitted. On a lateral side of the female blade, an elongated hole for inserting a base film from one lateral side to the other lateral side is formed as an insertion portion. | 08-19-2010 |
20110089228 | CONTINUOUS WORKING DEVICE - A continuous machining device includes: a film machining mechanism that forms a hole in a film; a holding mechanisms being provided integrally with the film machining mechanism; a slider that supports the film machining mechanism and the holding mechanism in a reciprocative manner relative to a feeding direction of the film; and a return mechanism that returns the film machining mechanism and the holding mechanism to their respective original positions defined on the opposite sides to the feeding direction of the film. When the film is held by the holding mechanism, the film machining mechanism can be moved in synchronization with the film. Thus, after the hole is formed in the film by the film machining mechanism, the film machining mechanism and the holding mechanism can be returned to their respective original positions by the return mechanism as soon as the film is released from the holding mechanism. | 04-21-2011 |
20120085479 | MANUFACTURING METHOD FOR PACKAGING BAG WITH ZIPPER TAPE AND MANUFACTURING APPARATUS THEREFOR - A zipper tape member having a male engagement portion and a female engagement portion formed on a surface of an elongated belt-like tape is pulled out, and is punched and removed at a portion corresponding to the male engagement portion and a portion corresponding to the female engagement portion at predetermined intervals. The zipper tape member is cut between the male engagement portion and the female engagement portion by a cutting member to be separated into a male belt-like member and a female belt-like member. The male belt-like member and the female belt-like member are heat-sealed to a base film, and a packaging bag is formed by a bag-manufacturing device. This arrangement is unlikely to cause a length difference or a tension difference between the male belt-like member and the female belt-like member, so that the zipper tape can be heat-sealed without any crease or adhesion failure. | 04-12-2012 |
