Talk:Lockstitch

Transverse shuttle machines
The article explains lockstitch formation in a hook-and-bobbin machine well (the animation is particularly helpful) but doesn't explain how a transverse shuttle machine makes this stitch. The sewing machine article is weak on this too. Transverse shuttle machines use a bobbin inside a shuttle on a long swinging arm. In some parts of the world they were the dominant domestic sewing machine technology for the first half of the twentieth century, though in America hook machines like the Singer 99k rapidly dominated the market. In Britain transverse machines like the Singer 48k and Jones CS remained very popular until the 1950s, possibly because they were cheaper to buy. I sort-of understand how a transverse shuttle machine works but don't have the detailed knowledge to write an authoritative article. --Ef80 (talk) 16:23, 19 November 2009 (UTC)


 * I am developing the Bobbin driver article to explain the differences in hook/shuttle/bobbin designs. Txinviolet (talk) 13:56, 15 August 2010 (UTC)

Lockstitch,gif is great
This is not a comment but a thank you to ru:user:NikolayS who created, I think, the gif of the lockstitch. That was very helpful. I don't think I would understand it so well without that graphic. --Bruce Hall (talk) 10:23, 5 August 2010 (UTC)

I don't know who to contact but the explanation of a lockstitch is totally wrong go to "How stuff is built" to get the correct description of lockstitch", doesn't anyone with even them minimum amount of experience look at this stuff? This explanation is just crazy. Signed, "A 35 year professional tailor".--User:63.196.195.43(talk) 16 March 2012(UTC)

Levitating bobbin?
In the GIF animation, the upper (yellow) thread seems to pass the lower (green) thread's bobbin on both sides. How is the bobbin kept in place if this is possible? Or am I seeing it wrongly? — Preceding unsigned comment added by SimonDeRidder (talk • contribs) 08:02, 16 July 2018 (UTC)

Removal or renewal of lockstitch animation due to error.
There's an error in the lockstitch gif where the yellow thread suddenly goes on the other side of the hook. This isn't physically possible, as it would require the thread to travel through a solid object.

Here is the error pointed out:

I've found other animations of the lockstitch that confirm that there is an error, though those animations are not, to my knowledge, public domain.

I've pointed this error out on the talk page for the animation file a few months ago, though I have had no responses. I don't have any replacements, but I think that erroneous material should be removed nonetheless.
