This video has some fantastic demonstrations of how sewing machines work. If you’re mechanically inclined then it’s definitely worth a watch. The mechanisms that grab, twist, and pull the thread are wonderfully clever and elegant.
I watched this video last night with my girlfriend, and it answered SO many questions I had about how they worked. The last time I touched a sewing machine (besides my seamstress grandmothers ancient singer that popped out of a table) was in middle school for home-ed class. I am a chemical engineer now, and it still baffled me that the needle only partially penetrated the fabric, yet a full stitch was completed. I was completely unaware of the mechanism inside the base that was allowing for the back side of the stitch. I sent this video to 3 other engineers I work with and we all found it very insightful/interesting to see how such a machine was developed.
I’m glad you liked it!
