Talk:Jacquard loom

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!

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.

Very interesting! Thanks

Useful, interesting, like the photos. I referenced this page re "algorithm". wvbaileyWvbailey 22:25, 20 June 2006 (UTC)

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.

I have seen the punch cards being used in the US and overseas in Belgium. They are still in existance and used an awefull lot. Most people use them

Baby wraps made by Didymos.de use a Jacquard process; I don't know whether they use the punch card machines or not, but the wraps are beautiful. You can see one of their looms here: http://www.didymos.de/english/html/jacquardwebstuhl.htm —Preceding unsigned comment added by 71.168.102.114 (talk) 21:03, 24 July 2008 (UTC)

This machines are in mainstream usage in France, they call them "leavers" and the whole lace industry depends on them. Some companies have managed to include electronic controllers on them, and others still work with thousands of punched cards —Preceding unsigned comment added by 84.77.96.100 (talk) 15:46, 10 January 2009 (UTC)

I understand that some of the weavers in Assam still use the Jacquard loom even today. If I find any news reports etc I will try to add that reference here as well -Deepraj | Talk 17:19, 11 August 2009 (UTC)

Invetion year?

Joseph Marie Jacquard mentions this invention as created in 1804-1805. In this article it mentions it in 1801, as well as in Computer. Not sure what to do with it. --RazorICE 07:05, 19 February 2007 (UTC)

YES, PUNCH CARDS ARE FOUND ALL OVER IN THIS INDUSTRY STILL BEING USED

Punch cards are hardly used anymore - the electronic Jacquard machines are on the market for over 10 years now and cards are a huge cost factor. They are still being used in specialty weaving (money not being a big factor there with huge profit margins) and people that took advantage of the near destruction of the US textile industry and picked up used machinery for next to nothing.

Don't see what the ad for Dornier has to do with Jacquard weaving.

First machine to use punched cards?

This article states in the section Importance to computing that the Jacquard loom was the first machine to use punched cards to control a sequence of operations. However, according to the articles Basile Bouchon and Joseph Marie Jacquard such cards were already used in 1728 by Falcon's improvement to Bouchon's invention, and Jacquard returned to that earlier approach.  --Lambiam 22:19, 17 January 2013 (UTC)
