Automatic thread trimming function: This electric thread trimmer combines vacuuming and trimming capabilities, automatically trimming loose threads to prevent damage to garments and avoiding accidental cutting of overlock or serger stitches. It effectively controls the length of residual threads to less than 1mm. Brushless motor configuration: This automatic fabric trimmer features brushless motors in both the vacuum and handle sections, providing a lifespan approximately ten times longer than traditional motors. It minimizes vibration for comfort during extended use and offers improved energy efficiency. Function and design: The intelligently designed square structure increases capacity by 35% and includes noise reduction and sound insulation features. The handle-style design incorporates a real-time temperature and speed display, and trimmed threads are automatically collected in an integrated tray for easy maintenance. Precautions: If the filter becomes clogged or is improperly installed, causing excessive negative pressure, the negative pressure check valve will activate to restore airflow, protecting the motor and control board from overload and overheating damage.
