摘要： An apparatus is improved to successively make plastic bags each of which includes an end surface provided with a spout, by employing the general feeding way of panel material, to be simple in structure, low in cost, high in speed and to make it possible to successively make the plastic bags two by two. A first folded portion is formed in a first web of panel material 1. An aperture is formed in a second web of panel material 2. A spout is inserted into the aperture, the spout and the second web of panel material 2 being heat sealed with each other. The second web of panel material 2 is guided by a guide device 18 to be folded after being heat sealed so that a second folded portion should be formed in the second web of panel material. The spout is turned over by the second folded portion. The second folded portion and the first folded portion are heat sealed with each other while the second folded portion and the second web of panel material 2 are heat sealed with each other about the spout.

摘要： At least one of a horn or an anvil includes protrusions that protrude from a facing surface thereof. Two panel parts and a gusset part folded and interposed between the panel parts are sandwiched and compressed by the horn and the anvil. Two portions of the gusset part are welded to each other by ultrasonic vibration of the horn during the sandwiching and compressing.

摘要： A first body of fastener material is joined to a first web of panel material while a second body of fastener material is joined to a second web of panel material. The first and second bodies of fastener material are interposed between the first and second webs of panel material and aligned with each other after the first and second webs of panel material are superposed with each other. A third body of fastener material is joined to a web of side gusset material to be interposed between the first and second bodies of fastener material after the first and second webs of panel material are superposed with each other, the first and second bodies of fastener material being aligned with the third body of fastener material.

摘要： In an apparatus for successively making plastic bags, a receiver plate 5 is fixed to a support plate 7. The support plate 7 extends widthwise of the webs of film material 2H and 2L to protrude on one of opposite sides of the webs of film material 2H and 2L. An elastic support device is disposed on the one side of the webs of film material 2H and 2L to elastically support the receiver plate 5 and the support plate 7. An attitude hold device is disposed on the one side of the webs of film material 2H and 2L to act on the support plate 7 so that the receiver plate 5 and the support plate 7 are held in attitude not to be inclined when being lowered and raised.
