How Does a Sewing Machine Work?

This has puzzled me for a long time; how the hell does a sewing machine work? But then I saw this tweet in my timeline the other day. How have I not looked this up before? It is pretty amazing.

Just as described in the article posted in the tweet above, how the up-and-down motion of the needle translated into a stitch had always intrigued me, I’m glad I wasn’t alone in that!

I always assumed that there was some clever mechanics underneath that worked the thread around the previous stitch, or at least something like that, but the rotating wheel had never even occurred to me.

Now, another question: how does the sewing machine evenly space out the stitches?

I’d assume that there is a measuring wheel that turns as you move the fabric along – like the ones that you see people using to measure a road, but I have no idea, perhaps there is another GIF out there for this… Anyone?
