FIELD: the invention refers to measuring equipment. ^ SUBSTANCE: the mode includes construction of mathematics model of sheet based on measured coordinates of points of lateral edges of sheet material with the aid of linear multielement photoreceivers. Initially with the aid of an immovable first linear multielement photoreceiver coordinates of both lateral edges of the sheet are defined, with whose aid the second and the third movable linear multielement photoreceivers are located over correspondingly the left and the right edges so that optical axles of the photoreceivers were at most approached to normals constructed from controlled points belonging to the edges of the sheet, in accordance with received results a mathematics model is constructed, at that the width of the sheet for each measurement is determined as the value of the section on the mathematics model of the sheet between the controlled points belonging to the edges of the sheet and it is computed in accordance with the declared expression, and the crescent for the both edges is determined as the utmost distance between the edges of the model of the sheet and the section connecting the extreme points each of lateral edges of the model of the sheet. ^ EFFECT: increases accuracy and reliability of measuring of sheet material, increases quality of production. ^ 2 dwg |
