A cross-lapper’s leaflet alignment drifted from roughly half a degree to a full degree each shift. The cause was a 1.5 mm drive-pulley error left after a bearing change — visible only once the machine was hot and loaded.
Engineering Note
Repeated blade jams on a textile cutting line caused motor-shaft failures and a recurring bottleneck. Overall downtime reduction improved from 50% initially to 80–85% after three jig versions, while cutting-related downtime reduced by approximately 90%.
Engineering Note
A cross-lapper kept wearing through shafts on a regular cycle. The cause was the support geometry, not the parts — here is how the support was redesigned.
Engineering Note
A cold-measured 0.2 mm alignment often drifts to 1.5 mm after 30 minutes under load. Here’s the 3-minute dial-indicator routine that catches pillow-block drift before it appears in the product.
Case Study
A label-tearing problem that looked like a labelling machine fault was actually caused by a conveyor drive belt running 3 mm beyond its pulley edge.
