These essential components transfer power from the motor to the machine’s moving parts, enabling needle movement and fabric feed. Different machine models require specific types, varying in length, width, and material composition, such as rubber or polyurethane. Selecting the correct type is crucial for optimal performance.
Proper power transmission ensures smooth operation, preventing skipped stitches and fabric jams. A worn or damaged one can significantly impact a machine’s functionality, leading to frustrating sewing experiences. Over time, these components can stretch, crack, or break due to wear and tear, necessitating replacement. Their development has mirrored advancements in sewing machine technology, evolving from simple leather straps to precisely engineered modern materials designed for durability and efficiency.
