Patent ID: 7343858

Claim:
A method of applying a registered pattern to a continuous web of material comprising the steps of: (a) capturing an image of the web, wherein the image includes at least two registration features; (b) computing registration corrections based on the registration features, wherein the registration corrections maintain registration between a next panel and a previous panel; (c) computing a transverse path correction necessary to maintain the next panel at a same transverse location relative to the web as the previous panel; (d) limiting the transverse path correction to a user-defined maximum if the transverse path correction exceeds the maximum; (e) computing a rotational path correction to substantially align the next panel with a longitudinal axis of the web; (f) limiting the rotational path correction to a user-defined maximum if the rotational correction exceeds the maximum; (g) computing a composite set of corrections by combining the transverse path correction and the rotational path correction with the registration corrections (h) computing a final set of corrections by adjusting the composite set of corrections according to a user-specified set of adjustments; and (i) producing the next pattern on the web according to the final set of corrections.
