Abstract
A method includes receiving a first image of a first line of perforations in a sheet product, processing the first image to determine whether the first line of perforations are within specifications, and outputting an indication to an operator indicative that the first line of perforations are not within specifications responsive to determining that the first line of perforations are not within specifications.
Claims19
A method comprising:
- receiving a first image of a first line of perforations in a sheet product;
- processing the first image to determine whether the first line of perforations are within specifications, wherein the specifications include at least one of a width of one or more perforations, a length of one or more perforations and a spacing of one or more perforations in the first line of perforations;
- outputting an indication to an operator indicative that the first line of perforations are not within specifications responsive to determining that the first line of perforations are not within specifications;
- adjusting a perforating arrangement by:
- changing, in response to the determination, an amount of a distance between an anvil roller and a perforations roller, wherein the sheet product is disposed between an overlapping portion of the anvil roller and the perforations roller which are disposed on opposing sides of the sheet product;
- and
- advancing the sheet product such that a subsequently formed line of perforations in the sheet product is within specifications responsive to determining that the first line of perforations is not within specifications;
- and
- forming the sheet product into a roll.

A system comprises:
- a first camera;
- and
- a processor operative to:
- receive a first image of a first line of perforations formed by a perforating arrangement in a sheet product from the first camera;
- process first image to determine whether the first line of perforations are within specifications;
- output an indication to an operator indicative that the first line of perforations are not within specifications responsive to determining that the first line of perforations are not within specifications, wherein the specifications include at least one of a width of one or more perforations, a length of one or more perforations and a spacing of perforations in the first line of perforations;
- and
- adjust a perforating arrangement by:
- changing, in response to the determination, an amount of a distance between an anvil roller and a perforations roller, wherein the sheet product is disposed between an overlapping portion of the anvil roller and the perforations roller which are disposed on opposing sides of the sheet product;
- and
- advancing the sheet product such that a subsequently formed line of perforations in the sheet product is within specifications responsive to determining that the first line of perforations is not within specifications;
- and
- forming the sheet product into a roll.
