摘要： A closed filled bag is formed using a cylindrical mandrel by feeding a bag forming sheet of a heat-sealable film which is of a web and is directed in a manner to one side of the mandrel so that it leaves two marginal edges on the opposite side of the mandrel which are guided into abutting relationship while the body thereof is formed into a cylinder around the mandrel. The zipper tape is fed to the mandrel and it is provided with spaced apart zipper elements which during feeding are folded into juxtaposition so that a U-shaped zipper tape is fed to the mandrel to overlie the two marginal edges which are of the bag forming sheet and the zipper tape has marginal edges below the zipper elements which are secured to the marginal edges of the bag forming sheet. During the forming of the bag forming sheet on the mandrel the product which is to be inserted in the package which will result is directed through the top of the mandrel and the sheet as it exits from the mandrel is sealed along its bottom as the bag forming sheet is fed further away from the mandrel a second seal is made across the top which encloses the material within the package. The sealing is advantageously made to extend through the zipper tape at both the top and bottom also.

摘要： A flexible bag has a releasable closure with a fin extending away from one of the mating pluralities of hook-like protrusions. The fin is joined to the base of the hook-like protrusions to apply disengaging force for opening the closure from the outside of the bag. The closure resists opening force from inside the bag. The protrusions have hook-like ends which have the same shape on all protrusions, which extend in one direction on one of the plurality of protrusions and in the other direction on the other plurality of protrusions. The protrusions are easily extruded from molten thermoplastic and applied to a moving web of film during an in-line bag manufacturing process.

摘要： A method of and apparatus for manufacturing stock material from which bags or other containers may be formed is disclosed. A folded plastic film is fed from a stock roll onto a plurality of carrier rollers which support the film in a horizontal position. Simultaneously, a separate closure strip is fed from a second stock roll through a guide block which aligns the strip with a sealing station, the two halves of the closure strip being pressed together to maintain proper alignment. The upper ply of the folded plastic film is fed into the heat sealing apparatus at the sealing station, the edge of the upper ply being aligned with one edge of the closure, and the film and the closure strip are fed continuously through the sealing station where they are welded together. The lower ply of the film web is folded downwardly so that it bypasses the sealing station. After the film and closure strip pass out of the sealing station, the lower ply is folded upwardly so that it coincides with the free edge of the closure strip. The film and closure strip are then fed through guide rollers and a second guide block which aligns the free edge of the closure strip and the edge of the lower ply of the film with a second sealing station, where these two edges are welded together. Thereafter, the completed stock material is fed to a take-up reel for storage or to a suitable bag forming machine.
