Method of applying a slider to a fastener-carrying plastic web

A method of applying sliders to a fastener-carrying web of plastic film, comprising:

• advancing said web of plastic film along a predetermined path;
• providing a fastener including first and second opposing tracks with respective first and second respective interlocking profiles and respective first and second fins depending from said respective first and second profiles;
• sealing one of said fins to said web of plastic film;
• folding said fastener away from said web of plastic film about said sealed fin;
• mounting sliders on said fastener at predetermined locations;
• and
• folding said slider-carrying fastener onto said web of plastic film.

A method of making plastic bags that have a fastener opened and closed by a slider, comprising:

• advancing a web of plastic film along a path;
• advancing a fastener along said path adjacent said web of plastic film, said fastener including first and second tracks, said first and second tracks including respective first and second interlocking profiles and respective first and second fins depending from said respective first and second profiles,
• sealing one of said first and second fins to said web of plastic film;
• folding said fastener away from said web of plastic film about said one of said first and second fins sealed to said web of plastic film;
• sealing said first and second fins to each other at selected locations;
• removing at least a portion of said first and second tracks and said first and second fins at said selected locations;
• mounting a slider at said selected locations onto said first and second tracks;
• and
• folding said fastener onto said web of plastic film.

A method of applying a slider to a fastener-carrying web of plastic film, comprising:

• providing a fastener including first and second interlockable profiles and a fin depending from each of said first and second interlockable profiles;
• attaching one of said fins of said fastener to said web of plastic film such that said profiles are immediately adjacent to said web;
• folding said attached fastener away from said web such that said profiles are spaced from said web;
• and
• applying the slider to said profiles of said folded fastener.

A method of applying a slider to a fastener-carrying web of plastic film, comprising:

• providing a fastener including interlockable profiles and fins depending from said respective profiles;
• attaching one of said fins to said web of plastic film such that said profiles are immediately adjacent to said web;
• folding said fastener away from said web about said attached fin such that said profiles and proximate portions of said fins are oriented at an angle relative to said web;
• and
• applying a slider to said profiles of said folded fastener.

A method of applying a slider to a fastener, comprising:

• providing a fastener including interlockable profiles and fins depending from said respective profiles;
• folding said profiles relative to distal portions of said fins such that said profiles are oriented at an angle relative to said distal fin portions;
• attaching one of said distal fin portions to a web of plastic film such that said profiles and proximate portions of said fins are oriented at an angle relative to said web;
• and
• applying a slider to said profiles of the folded fastener.
