Bobbin Case Opener (91-176 340-91) | For Pfaff 1445
Ensure flawless thread passage and consistent stitch quality with the Bobbin Case Opener (Part #91-176 340-91). This precision-calibrated component is essential for the high-speed rotary hook system of the Pfaff 1445, specifically designed to handle the demands of heavy-duty industrial sewing.
The Secret to Smooth Thread Clearance
The bobbin case opener (also known as the "finger" or "lever") plays a critical role in the stitch cycle. Its job is to momentarily pull the bobbin case back, creating a tiny gap for the thread to pass freely around the hook assembly. If this part is worn or misaligned, you will experience thread shredding, tension spikes, and the dreaded "bird-nesting" under the fabric.
Key Performance Features
Optimized Timing Geometry: Engineered to move with microscopic precision, providing the exact clearance needed for heavy bonded nylon and polyester threads.
Anti-Friction Finish: Features a micro-polished surface to ensure the thread glides over the opener without snagging or fraying.
High-Tensile Durability: Manufactured from hardened industrial steel to resist the constant mechanical wear and vibration of a triple-feed machine.
Direct Compatibility: A high-quality replacement for part 9117634091, matching the original factory specifications for the Pfaff 1400 series.
