System and method for ensuring cutting accuracy in a mailpiece wrapper

A mailpiece fabrication system for assembling finished envelopes from content materials and from wrapping materials, wherein the wrapping materials are comprised of a continuous web of printed substrate, the printed substrate including printed envelope information and cut quality marks for individual envelopes;

• the system including:
• a conveyance deck upon which the continuous web is transported while content materials are placed on the continuous web and the continuous web is folded around the content materials to form a continuous tube enclosing the content materials;
• a cutter downstream of the conveyance deck for cutting individual envelopes from the continuous tube of folded wrapping material;
• an imaging device for optically imaging each of the individual envelopes and capturing image data indicative of a cut quality mark on the individual envelopes;
• a controller receiving image data from the imaging device and configured to compare an actual dimension of an imaged cut quality mark with an expected dimension of a cut quality mark and the controller producing an error signal if a difference is not within a predetermined tolerance;
• an outsort station downstream of the imaging device, whereby the controller controls the outsort station to outsort defective envelopes in response to the error signal;
• and
• wherein the controller provides a feedback signal to a transport mechanism associated with the conveyance deck as a function of the difference between the actual dimension and the expected dimension of the cut quality mark;
• and whereby a speed of the transport mechanism is adjusted to correct the difference.
