发明名称 In line application of closure to packaging film.
摘要 A method and apparatus (10) for applying a pair of continuous narrow interengageable strips (16,18) of reclosable fastener material to a web of film material (20) in line with horizontal form, fill and seal apparatus (14) to provide a reclosable package. The fastener material is secured within a longitudinal fold in the web (20) of package film material, and the web (20) then proceeds directly into a form, fill, seal machine (14) in which the web (20) is oriented horizontally, and the product (24) is placed on the web. The web (20) is then wrapped upward around both sides of the product (24) to bring the edges together to form a longitudinal fin seal (122), and subsequently the ends of the package are sealed by transverse sealing means (128), and the ends of the package are cut from the web (20) to separate the finsihed package from the preceding and succeeding packages. <IMAGE>
