Was sind die häufigsten Ursachen für Fadenbrüche in Nähmaschinen?

Thread breakage is one of the most common issues in sewing machines, especially in high-speed industrial sewing like mattress manufacturing. Frequent thread snapping slows production, reduces stitch quality, and increases downtime. Understanding the root causes and solutions will help keep operations smooth and efficient.

1. Incorrect Threading of the Machine

Why It Happens?

cURL Too many subrequests. thread is not properly guided through the machine’s tension discs, guides, or take-up lever, it can snag, tangle, or break.

How to Fix It?

• Follow the machine’s threading diagram carefully.
• Ensure the thread passes through all tension points correctly.
• Rethread the machine if the thread jumps out of place.
• Regularly clean thread paths to remove lint or debris that could cause resistance.

2. Incompatible Thread and Needle Combination

Why It Happens?

Using the wrong thread thickness with an unsuitable needle size creates excessive friction, leading to snapping.

How to Fix It?

• Match thread weight with an appropriate needle size:
  • Lightweight fabric → Fine thread + Small needle (Size 9/70)
  • Heavy-duty fabric → Thick thread + Large needle (Size 18/110 or 20/125)
• Use polyester thread for strength in heavy-duty sewing like mattress production.
• Check the needle’s eye size—a small eye can cause thick thread to cURL Too many subrequests..

6. Obstructions in the Thread Path

Why It Happens?

Lint, dust, or rough edges on tension discs, guides, or bobbin cases können catch and break the thread.

How to Fix It?

• Clean tension discs, thread guides, and bobbin area regularly.
• Use compressed air or a small brush to remove lint buildup.
• Inspect the thread path for sharp edges—polish rough spots if necessary.
