[edit] Images
I've tidied up the image positioning, which I think makes it look better. The only problem might be the appearance on smaller monitors. If anyone has a problem, then we'll need to have a re-think. I was going to sacrifice one of the images, but I thought they were brilliant, so I've left them all. Noisy | Talk 10:03, 1 Oct 2004 (UTC)
You might like to have another look as if the righthand picture is located to its left then the words 'The term...' are to the right of the right hand picture (RHP). If the RHP is moved to the right the words 'The term...' end up being between the pictures. I have no idea how to correct this typographical error. Over to you!
[edit] Mails?
The new comment added to one of the illustrations uses the term mails. What does this mean? Noisy | Talk 10:16, Mar 20, 2005 (UTC)
If anyone is going to write about technical stuff in a specific industry I believe it is important that they use the correct terms - either through personal knowledge or by looking them up!
The term 'mail' in a jacquard loom is the piece of long metal through which a warp yarn is threaded. The weight is attached to the bottom of the mail and the harness to the top of the mail. The harness goes through the comber board which allows the relative positions of the individual parts of the harness to be maintained. The picture is NOT of the hooks as originally and incorrectly entitled. The hooks cannot even be seen in that picture!
I would care to guess that the term 'mail' came from the use of one or more very small metal rings instead of a thin piece of metal. The small rings, I suppose were like the rings used in chain 'mail'. However this is just supposition on my part.
Attached below the mail is a long thin weight called a "ling" which holds the harness down. This weight allows the harness to drop quickly so weaving can continue at speed.
[edit] Very interesting! Thanks
Useful, interesting, like the photos. I referenced this page re "algorithm". wvbaileyWvbailey 22:25, 20 June 2006 (UTC)
Geez...someone here needs to take a happy pill. Take it easy guy, it's not so bad using wrong terminology once in while. (Were you considered a dork in high school? just wondering)
[edit] punch cards?
Are punch card controlled machines still in commercial use? I suspect so, since they might be simpler to maintain than electronic computerized versions. But it would be good if the article said, one way or the other, if anyone knows for sure. 69.87.200.111 01:56, 14 September 2006 (UTC)
They are still used in the developing world. They have nearly disappeared in the US. I have seen them sitting in mills in the US, but can't guarantee they are being used. Creating those punch card sets is time consuming and expensive compared to the electronic system.
