Abstract
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.
