Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. An apparatus for threading a material layer through a machine path, the apparatus comprising a forwarding series of blowing air mechanisms aimed at said material layer in a machine direction to guide said material layer in said machine direction forwards through said machine path until an acceptable material state is achieved; a sensor; and a reversing series of blowing air mechanisms aimed at said material layer in a reverse machine direction to guide said material layer in said reverse direction; said sensor operatively coupled with said forwarding series of blowing air mechanisms and operatively coupled with said reversing series of blowing air mechanisms; at most one of said forwarding series of blowing air mechanisms and said reversing series of blowing air mechanisms instantaneously operative upon said material layer.
