METHOD AND DEVICE FOR DETECTING SYNCHRONISING MARK, USED IN SYNCHRONISED POSITIONING OF AT LEAST ONE IN ESSENCE CONTINUOUS MATERIAL CANVAS

摘要

FIELD: medicine. ^ SUBSTANCE: products contain printed drawings or analogous obtained by processing elements, material canvas is intended for its separation into segments of nominal length (LN) of separation and contains synchronising marks with periodicity (Ls). Method includes: detection of corresponding synchronising mark for placement of corresponding drawing in earlier determined place on corresponding product, said detection being performed along earlier given in machine direction longitudinal section of said material canvas. Invention differs by the fact that method includes: detection of given synchronising mark by determining difference of its colour or colour combination from colour or colour combinations on remaining part of given section. Invention also relates to device for said detection and to absorbing product. ^ EFFECT: group of inventions allows to ensure possibility to use larger part of product surface for printing of drawings, ensure more reliable detection of synchronising mark. ^ 13 cl, 4 dwg
