Autosetpoint registration control system and method associated with a web converting manufacturing process

An automatic control method suitable for use in connection with a high speed web converting process for manufacturing a composite article from a sequential addition of component parts during a production run of composite articles, said method comprising:

• detecting a placement of a first component part using a first sensor, said first sensor operating at a first set point to trigger a length control action as a function of the detected placement of the first component;
• generating an image indicating a position of the first component part using a second sensor positioned to detect said position of the first component subsequent to the length control action;
• comparing to a target the position of the first component part indicated in the generated image;
• and
• selectively adjusting the first set point as a function of a difference between the position of the first component part indicated in the generated image and the target.

An automatic registration set point control system being suitable for use in connection with high speed web converting process for producing a composite absorbent article from a sequential addition of component parts during a production run of composite articles, said system comprising:

• a first sensor positioned to detect a placement of a first component part, said first sensor operating at a first set point to trigger a registration control action associated with the placement of said first component part;
• a second sensor positioned apart from the first sensor, said second sensor generating an image indicating a position of the first component part subsequent to the registration control action associated with the placement of the first component part, said second sensor providing an inspection parameter indicative of the position of the first component part;
• and
• a processor obtaining the inspection parameter and comparing said inspection parameter to a target, said processor determining an amount of adjustment to the first set point as a function of a difference between the inspection parameter and the target.
