Woven Upper Tear During Lasting | Real Footwear Manufacturing Insight
Woven Upper Tear During Lasting | Real Footwear Manufacturing Insight Woven Upper Failure During Lasting – A Real Production Moment During the lasting process, excessive tension can cause woven leather uppers to fail under pressure. This clip captures a real structural tear occurring while shaping the upper onto the last. What Happens in This Video? At 00:00 , rapid lasting begins. The upper is pulled into position, and structural tension starts building across the woven surface. By 00:02 , pressure increases significantly in curved zones — especially around the toe area where stress concentration is naturally higher. At 00:04 , the woven upper separates under tension. This is not a cosmetic issue — it is a structural response to stress imbalance. At 00:06 , we see a glimpse of reinforcement preparation, which will be applied in the next stage to correct the issue. Why Does This Happen? High tension at curved zones Insufficient support underneath...
