Winder registration and inspection system

A system for monitoring defects suitable for use in connection with a winder producing a rolled product from a web, the winder comprising a web transport apparatus for conveying a web and a plurality of independent winding modules onto which the web is rolled to form the rolled product during a winding process, each of the plurality of independent winding modules defining a cross direction generally perpendicular to the direction the web is conveyed by the web transport apparatus, the system comprising:

• a plurality of first sensors associated with at least one of the plurality of independent winding modules, the first sensors positioned to scan across a width of the web transport apparatus at a location downstream of the winding module, each the plurality of first sensors configured to detect a defect during the winding process;
• a second sensor associated with at least one of the plurality of independent winding modules, the second sensor positioned to scan across the cross-direction of the winding module at a location proximate the winding module, the second sensor configured to detect a defect during the winding process;
• a controller coupled to the plurality of first sensors and the second sensor for each independent winding module, wherein the controller determines that the winding module has initiated the winding process, and wherein the controller directs both the plurality of first sensors and the second sensor to scan in response to the determination of initiation of the winding process.
