Troubleshooting the Thread Cone

Here are several things to watch for with the Thread Cones to ensure best performance from your machine  To rule out situations below, it is recommended to always use a New Unused Cone.


  • Make sure you don't have a Bruised Cone.

If a cone has been dropped or bumped into, the threads may have shifted. This can cause the thread to cast off the cone less freely and create thread breaks. As you rethread the machine, pull on the thread with the pinch roller up and see how it pulls. If the cone is damaged, it may pull easily for a bit and then feel as though it is being pulled across sandpaper. This can cause thread breaks. Some cones can be saved by casting off thread until you are past the damaged part of the cone.


  • Check for Burs on the Plastic Cone.

This can catch thread as it's feeding through the machine. Remove any rough spots from the plastic cone with a fine sandpaper or emery board.


  • Avoid using Aged Cones.

Old thread can be brittle and more likely to thread break.


  • Avoid using cones with Exposure Damage.

Moisture can damage thread, for example thread swelling in humid environments. Also watch for other types of exposure damage.
