Abstract
A pretreated-cardboard stripper that obtains a cardboard item and strips or blanks the cardboard item using laser cutting, die cutting or other techniques. The cardboard item may be a single item or multiple sections that are jointed together. After stripping or blanking, the stripper operates to sort the sections and joints from the waste by a vacuum sorter. The vacuum sorter includes a vacuum chamber with openings along its surface or certain areas of the surface and a peeler. After stripping, the pre-treated cardboard is transferred by the peeler along the surface of the vacuum chamber. The waste of the cardboard (areas between the sections and joints) may be coupled to the vacuum chamber surface while the pre-treated cardboard is being transferred by the peeler along the surface of the vacuum chamber, which has the advantage of operating to disconnect and thus sort the waste from the sections.
