Abstract

Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. A first non-elastomeric layer is bonded with an elastomeric layer, and to a second non-elastomeric layer. The apparatus and methods provide defect detection in the elastomeric layer and triggers an unthreading/rethreading sequence. Web defect detection may be provided by way of at least one visual inspection station. If defects are detected in the elastic layer, the resulting products may be culled.
