What later 20th-century machine specializations further drove factory efficiency and quality control?
Answer
Specialized equipment dedicated to buttonholes, serging, and hemming.
While the initial sewing machine established the foundation for mass garment production using the lockstitch, the evolution of machinery continued into the later 20th century. Efficiency gains were further realized through high specialization. Manufacturers moved beyond general-purpose machines to acquire specialized equipment dedicated to specific, repetitive tasks like creating buttonholes, applying serged edges, or performing final hemming. These targeted tools enhanced both the speed of output and the overall consistency and quality control within the factory environment.
