Troubleshooting the Upper Thread Path

The upper thread path should run smoothly the entire way from the cone of thread through the eye of the needle. If there is a rough spot or the thread does not follow the proper path, thread breaks are more likely. Look for the following issues when troubleshooting a thread break.

Thread Does Not Follow Proper Path

If it is wrapped around the thread tube or missing from one of the thread guides, it will not sew as reliably.

As you are rethreading the machine from a thread break, make sure that the thread follows the proper path. See how in the upper threading section.

Damaged Cones of Thread (Bruised Cones)

While not the most common cause of thread breaks, damaged cones can create issues for embroiderers. If a cone has been dropped, 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.

The age of the thread and exposure to the elements can also weaken thread. Storing your thread where it is shielded from the elements and light can help prolong the life of your thread.

Change to a different cone of thread. Some cones can be saved by casting off thread until you are past the damaged part of the cone.

Rough Spot in the Thread Path

Check along the thread path for any rough areas. You may find that the cone of thread has a rough spot on the plastic core. This can catch thread as it is being cast off and fed through the machine.

Remove any rough spots from the plastic core with a fine sand paper or emery board.

Thread Wrapped Around Thread Tube

If the thread wraps around the thread tube at the top of the cone, the thread will most likely break. This is usually caused from the thread tube being extended too far above the cone.

Adjust the thread tube to extend just above the cone. Extend it about ½".

Thread Pulling Across Top of Cone

As thread casts off and runs through the system of the machine, it pulls through the thread tube quickly. If the thread tube is not extended far enough above the cone, the thread can pull across the top of the cone and create thread breaks.

Adjust the thread tube to extend just above the cone. Extend it about ½".

Thread Pooling Below Cone

If the thread cones are not properly seated on the thread tree of the AMAYA, vibration from the machine can cause the cones to spin and/or the thread to cast off and puddle at the bottom of the cones. As thread collects below the cone, it can catch before being fed into the machine. This can cause extreme tension on the thread and cause the thread to snap.

If using large cones, be sure to sit the cone snugly on the thread tubes. If the cones wobble, install a thread clover on the thread tube before loading the cone of thread. The clover will expand inside the cone and prevent it from wobbling.

If using smaller spools of thread, you may need to use a thread cone/spool holder to prevent the thread casting off from falling under the spool base.
