Tensioners for Bobbin Winding
Here are some pictures of "tensioners." They're a small post with a springy part. When you wind a bobbin, you need to wrap the thread all the way around the tensioner. On most machines, it makes a "figure 8" as it wraps around. If the thread doesn't go into the tensioner properly, you'll get a sloppy, loose bobbin.
