Craft:

Jeremy is right. You can picture the loop of top thread getting around the bobbin cuz it does float freely with no axle. BUT the does no explain (or show in the vdo) how the loop can encircle the red race freely. The red race MUST be attached to the machine somewhere (unlike the bobbin spool). So, how does it work?

Great animation!

jeremey- the centre circle is the bobbin; the red part is a shuttle race. The bobbin sits inside the shuttle race and the two work together. The green thread comes from the spool at the top.

i think

This is an awesome animation. I've sewn for years and wondered how the the threads connected together. My husband, an engineer, thought the animation was equally cool!

that is totally crazy. when i sew i was wondering how that bobbin works. now i see.

THANKS for posting this, seriously. The timing was all screwed up on my machine this summer and I searched EVERYWHERE for something just like this. I ended up having to leave it with a repair place, which took 3 weeks and $90, bleh.

This is a cool graphic, but i don't understand quite how it works. the center bobbin that holds the blue thread seems to be floating in space if the green thread is flowing around it. meanwhile, the red part is floating in space as well. if someone could please explain how it works in practice i would really appreciate it.

wow! i always wondered how that worked! thanks for that!
