High-Speed Nap Attachment Technology

Automated nap-bonding systems now apply adhesive and attach fabric in one continuous process. Computer-controlled dispensers precisely measure hot-melt adhesive while maintaining optimal 320°F temperature. The fabric is tensioned to ±1% accuracy before contact with rotating cores. "Our laser-guided system positions seams perfectly," explains engineer Maria Gomez. After bonding, rollers undergo compression curing at controlled humidity. Modern lines process 1,200 rollers/hour with consistent quality. Recent innovations include eco-friendly adhesives that reduce VOC emissions by 40% during production while maintaining superior bond strength in wet conditions.
