drcharlemagne Report post Posted February 5, 2013 Hello everybody, today I would like to ask a simple question. I can never remember which way to install the bobbin. Is there an easy way to remember which way it is supposed to unwind? Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted February 5, 2013 By force of habit and an abundance of caution, I usually install bobbins so they feed backwards through the slot. I believe that this practice started decades ago with high speed rotary shuttle machines, before anti-spin springs were introduced into bobbin cases. If the bobbins are loaded so that they feed in the same direction as the hook rotates, they tend to unload themselves and may even form knots. I always load them backwards on my rotary hook machines, even if they have anti-spin springs, to avoid having them unload all over the bobbin compartment.

Absolutely a must to do this on high speed machines. Right on Wiz. It helps prevent "backlash". The machine stops and the momentum of the bobbin keeps it spinning. Some machines are very unforgiving if the backlash isn't controlled. Alluminum bobbins help a lot because they're lighter than steel. As Wiz mentioned, there are several ways to control it. By far the most effective I've ever seen was made by Union Special. It was a standard small steel bobbin and the case had a small magnet recessed in the back. It's about the diameter of a pencil.

drcharlemagne Report post Posted February 5, 2013 Ok, so does that mean that the thread makes sort of an acute angle at the slot as it goes back toward the exit hole keeper thing? Quote Share this post Link to post Share on other sites
