发明名称 Method and apparatus for making reclosable plastic bags using a pre-applied slider-operated fastener
摘要 A method and apparatus for making reclosable plastic bags is provided. In the method and apparatus, a fastener is attached to a moving flat web of plastic film, preferably in the direction of web movement and near the center of the web. A plurality of sliders are mounted to the fastener either before or after the fastener is attached to the flat web, but prior to conveying the web to a FFS machine. The flat web, with the slider-operated fastener already attached thereto, is then conveyed to a vertical or horizontal FFS machine where the flat web is formed into bags, and the bags are successively filled and sealed.
