[edit] Sewing machine article - Miscellaneous info
This portion of the article is vague, misleading, and not terribly helpful.
For one thing, the instructions for threading a sewing machine do not relate to the most common type of machine and appear to be for a serger--a specialty machine which is quite different. I'm not sure if they're correct, not being a serger user myself.
The instructions on sewing just don't seem like the sort of material a reader would be looking for here .
If I had time and proper expertise, I'd write something, but I'm just trying to figure out why my machine is skipping stitches, and this was the first hit on Google. --70.231.140.143 00:04, 17 January 2006 (UTC)
- This is an encyclopedia, not a Help Desk. If you need help with your sewing machine, read the manual or contact the manufacturer's Customer Service Department. —QuicksilverT @ 18:56, 21 September 2006 (UTC)
The introductory information at the top of the article needs a complete rewrite. The first paragraph is incorrect: Most industrial machines do not produce an overlock stitch. Chain stitch is not, as implied, obsolete. The second paragraph is so tersely telegraphic as to be unreadable. Let me suggest the following as a starting point for further discussion:
REMOVED Since another user approved my proposed copy and moved it into the article, I am removing the proposed copy from this discussion page as redundant and no longer necessary.--Sfriedberg 03:21, 2 October 2007 (UTC)
[edit] Modern info section needed
This page is all history. I came here wanting to know what modern machines do, are rotary shuttles still used, how different feet work (I remember using complicated feet thirty years ago to make curtains with great success). Nothing! Perhaps someone can remedy this. Photo's of shuttles and diagrams of stitches would help. --86.135.122.223 15:41, 20 August 2007 (UTC)
Looking again I see to my surprise that this talk page is full of stuff that could well have been put straight into the article. Normally this page is for talk about the constructing the article! Still need basic descriptions though. --86.135.122.223 15:46, 20 August 2007 (UTC)
[edit] How do they work?
Sewing machines are among the most mysterious devices out there. Intuitively, to sew something (just like to tie a knot) you have to let go of something at some part of the process. But machines aren't good at letting go of things and grabbing them again. Somewhere there needs to be an explanation of how the thread goes all the way around the bobbin without getting tangled in whatever it is that keeps the bobbin turning. HowStuffWorks has an animated diagram that gives the impression the bobbin just turns by itself. Are sewing machines covered by the magician's code? If people think this explanation should be under lockstitch, there should be an indication here that the explanation of how it works is there.

Mark, I have been thinking about doing a series of animations that illustrate how the various stitches are formed, but this is a very low priority right now. To answer your questions without the benefit of pictures, the bobbin is surrounded by the hook which is mounted on the end of a rotating shaft. The hook captures the needle thread loop and guides it so that the thread does not simply wrap around the shaft. There are rotating-hook machines and oscillating-hook machines and they guide the thread in quite different ways. If I am looking at the same animated diagram of a rotating hook that you are, there is an error due to simplification. The half of the needle thread loop toward the view does pass over the free end of the bobbin, hook and shaft as shown. However, the other half of the needle thread loop can not pass through the shaft as shown in that animation. It remains to one side of the shaft until the other side of the loop has passed around the bobbin and hook.
The details of how sewing machines work would fill a book on mechanical movements, and you would have to get into dynamics (loop thread formation) as well as kinematics. You can reasonably ask for more detail, but it may be unreasonable to expect Wikipedia to provide the content usually found in a college engineering library or specialist literature. You might want to visit Vintage Sewing Machines for a more diverse set of stitch animations.
Examples of Probably-Too-Much-Information detail: The bobbin rotates only as the bobbin thread is drawn out. It spins freely within the hook, not driven by any mechanical mechanism. The hook, on the other hand, is rigidly attached to a power shaft which can be oriented either vertically (double-needle machines always are set up this way) or horizontally. The exact way the hook works depends on the shaft orientation as well as whether the shaft rotates or oscillates. It can even make a difference whether the shaft is horizontal in-line with the feed direction or horizontal perpendicular to the feed direction. And there are still a few sewing machines based on a shuttle mechanism, which predated the cylindrical hook, that form a lockstitch differently (although a topologist would say they work like oscillating-hook machines.) --Sfriedberg 00:35, 15 November 2007 (UTC)
[edit] REVISION NEEDED
Sorry to be blunt, but I came across this article tonight and it is in need of a major re-write by someone qualified in both grammar and expertise on the subject. The article itself starts without any sort of definitive opening - such as a definition of what a "sewing machine" is. It instead starts right out talking about chain stitches! There should be a paragraph describing what a sewing machine IS - it is a machine for using thread to stitch (bind) together pieces of fabric, in order to create objects out of textiles, including clothing, upholstery, etc. Then it should give a history, types of machines, major makers, etc., instead of giving any sort of direction on how to use one - that should be put into separate articles (perhaps in WikiHow.) Anyway, not to be disrespectful, but I was genuinely looking for some info on sewing machines and this article was very confusing, and had many grammatical errors. If I knew more about sewing machines I would do it myself. Poppapo (talk) 07:58, 30 November 2007 (UTC)
- I agree. And what in the world is meant by the "industrial revolution?" Please be more specific, there were dozens of industrial revolutions all around the world. Wolfdog (talk) 02:48, 15 January 2008 (UTC)
Over the next few days I can try to work on some of the introduction and history sections. I just finished a paper on the history of the sewing machine, so I know a bit about that. I'm not a great writer, but it would be hard for me to make this worse than it is. :) Shoshonna (talk) 20:53, 21 January 2008 (UTC) i agrre gh gadsww yoiyiyiyi —Preceding unsigned comment added by 86.7.223.74 (talk) 19:33, 19 February 2008 (UTC)
