Zipper Direction

[fredk]

umm, mike, pardon me but I think you're not thinking straight.

Lay a zipper down, the closed tag end to the right, the pull has to go left to right to open up the zip.

Now turn that zipper 180*, with the closed end on the left. The pull has now to go right to left to open up the zipper

same zipper orientated in different directions.

pardon me if I'm getting your message wrong

 

I should have made it clear in my previous posting that the zipper was pulled left to right to open it.

I don't think that ( turning the sliders the other way ) will work with all forms of zippers, some ( all the ones that I have here, a few hundred in different lengths, from 10 cm up to around 100 cm, or maybe 120 cm ) have one direction only "meshing" teeth, and the slider has to face in such a way as the meshing of the teeth happens inside it as it moves "forwards" and the zipper sides comes out "meshed" , at the rear of the slider as it runs "head" first..It splits the two sides if it is run ( still facing the same way ) "backwards" along the "meshed" zipper line. Mine are all for garments or maroquinerie though..I think that the marquee that we have in the garden might have zippers like your zippers ..but it is 01.20 am..here so I'm not bothering to go out and leave my glass of leapfrog to fend for itself in here Nor explain to Mdme just WTH I'd be doing at this time of night playing with the zippers on the marquee

Turn sliders to go either way . I always use ( Coil zippers ) when I can, And buy zippers by the rolls. So I cut to random lengths to what I need . mostly use #5, but the larger items I always try to give strong/beefy if possible with #10 's .

edit add:

I guess some people buy the zippers that are already prefab. with stops and the sliders installed . The illusion of one-way is there, but I think a lot of teeth are multi-directon of zip, with the Slider determining the zip/unzip direction .

I tried on some of mine ( that were inside ) ..they are bought ready made at various lengths..they'll only work if the slider is facing one way around..I accidentally pulled a slider off yesterday , so I had one to "play with" :) Looking closely ( magnifying glass ) at the teeth on all my zips, they definitely have a "direction"..I very rarely have used "coil zips" and even more rarely rolls, last time must be 30 years ago :) But then we're working different "niches".

Must go look at the marquee ones in the morning..I'm sure they'll be like yours, they must be at least 250cm each..some with two sliders..which are certain to work like yours as they definitely are not both facing the same way on the zips. :)
