Bobbin Case Opener for Industrial Walking Foot Machines - Part # 22...
Description
Description
The Bobbin Case Opener (part # 224004) is a steel replacement component designed for heavy-duty industrial walking foot sewing machines. This part is essential for managing the movement of the bobbin case during the stitch cycle, ensuring smooth thread passage in high-speed industrial environments. The opener helps move the bobbin case slightly at the correct moment, allowing the upper thread loop to pass freely around the case to form a lockstitch.
Specifications:
- Part Number: 224004
- Type: Replacement (aftermarket)
- Material: Durable steel construction
- Application: Industrial walking foot sewing machines
- Function: Manages bobbin case movement during stitch cycle for smooth thread passage
- Associated Parts: Works with mounting screw Part #200118
Machine Compatibility:
Singer Models: 111W class, 211W class (including 211G, 211U, 112W). Typically excludes subclasses 111W151 and 211W151.
Consew Models: 225, 226, 255 series
Juki Models: LU-562 industrial walking foot machine
Key Function and Use:
The bobbin case opener is a critical component in the hook assembly of industrial walking foot machines. It performs two essential functions: Thread Clearance - The opener helps "open" or move the bobbin case slightly at the correct moment during the stitch cycle, allowing the upper thread loop to pass freely around the case to form a lockstitch. This precise timing is essential for proper stitch formation in high-speed industrial sewing. Stability - The opener works in conjunction with mounting screw (Part #200118) to remain securely positioned within the hook assembly, ensuring consistent performance even under the mechanical stress of continuous industrial operations.
Function & Benefits:
This bobbin case opener is constructed from durable steel to withstand the mechanical stress and high-speed operation of industrial sewing machines. A worn, damaged, or missing bobbin case opener can cause thread jams, skipped stitches, or incomplete lockstitch formation, resulting in poor stitch quality and costly production interruptions. Replace a worn opener to restore proper bobbin case movement and ensure reliable, professional-quality stitches in heavy-duty industrial sewing applications.
Installation Note:
Install the bobbin case opener in the hook assembly, securing it with mounting screw Part #200118. Ensure the opener is properly positioned to allow correct bobbin case movement during the stitch cycle. Consult your machine's service manual for specific installation instructions and positioning requirements.
