VIKINGSANORDNING OCH FÖRFARANDE FÖR KONTROLL AV VIKING

Patentradars sammanfattning

Plockmatic International's folding device targets post-processing of inkjet-printed sheets by employing two sequential fold roller units (each a contra-rotating pair) mounted on a common distancing unit that sets both inter-roller gaps (D1, D2) simultaneously based on sheet thickness. A secondary distancing unit—implementing a rotatable eccentric cam arrangement driven by a dedicated motor—can then independently fine-tune the second roller gap (D2) during the second folding stage, after the sheet enters the downstream roller pair. A folding blade with a straight edge initiates the fold by pressing the sheet's front face into the first roller nip, while spring element arrangements on the first unit maintain consistent nip pressure perpendicular to sheet travel. The architecture decouples coarse gap calibration from fine, stage-specific pressure control, reducing ink transfer and sheet damage for rubber-surfaced rollers used with modern inkjet output.
