Abstract: The present invention relates to a calibration system (30) and a calibration method for a converting machine (20) provided with a die-cutting tool (18?) and at least one transfer unit (25) for transporting a sheet (1) along a travel path in a direction of conveyance (D) through the converting machine. The calibration system comprising a first image sensor (33), a memory (36) and a control unit (34). The calibration system is configured to detect an actual position of an indicia (42) on the sheet (1) and compare with a reference position of the indicia (42) stored in the memory (36). A correction program stored in the memory is executed when at least one of the longitudinal displacement (?xi) and the lateral displacement (?yi) of the indicia exceeds a predetermined tolerance threshold (Txi, Tyi).

Abstract: A quality-control device (200) includes: an illumination system (202) for illuminating one peripheral face of each folding box, an image capture device (204) for forming a multiple image of the respective peripheral faces of a bundle of folding boxes, an image processing system (206) for: i) detecting within the multiple image each peripheral end of the slots of each box that separate its adjacent flaps, ii) generating a data set indicative of the geometry of each peripheral end, and iii) analyzing the data set to determine the width of each peripheral end.
