Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. The apparatus and methods provide defect detection both before and after application of component patches to a traveling web to create a product. Web defect detection may be provided by way of at least one visual inspection station located upstream from the patch applicator. Patch defect detection may be accomplished by way of a visual inspection station located proximate the patch applicator. If defects are detected in either the traveling web or the component patch prior to patch application, patch application may be prevented until both a satisfactory web and patch are provided. If defects are detected after patch application, the resulting product may be culled. Furthermore, the apparatus may be provided with diagnostic software to warn against extant or imminent machine complications.
1. A method for correcting defects in a running web comprising: creating a running fold having a cross-direction fold width in an initial condition along a machine direction of a running web supplied at a feed rate;monitoring said running fold for a predetermined change in cross-direction fold width
1. A method for correcting defects in a running web comprising: creating a running fold having a cross-direction fold width in an initial condition along a machine direction of a running web supplied at a feed rate;monitoring said running fold for a predetermined change in cross-direction fold width of said fold width from said initial condition;upon detection of said predetermined change in said cross-direction fold width of said fold width from said initial condition, initiating a correction sequence to restore said running fold to said initial condition; wherein said correction sequence further comprises the steps of:engaging a mistrack correction roller against the running web; anddisengaging said mistrack correction roller from the running web. 2. A method according to claim 1, wherein, if said fold width is too narrow, said correction sequence further comprises the step of urging a folding plow into engagement with said running web. 3. A method according to claim 1, further comprising a step of increasing said feed rate after engaging said mistrack correction roller and then decreasing said feed rate after the step of increasing said feed rate.
