DEVICE AND METHOD FOR DETERMINING A BENDING ANGLE OF A SHEET AND THE USE THEREOF FOR THE ANGLE-BENDING OF SHEETS

摘要

A kind of bending angle the present invention relates to determining plate is that have the method bent along folding line, including generate at least one light beam, these light beams use a part of which side lies bending line to be checked of two points or line segment to sheet material to project. The thin slice that the beam forms incidence angle is known in advance with bending line. These points or line segment are imaged onto the distance between reception device and point or line segment is determined, this, which has, is projected to reception device. The wave beam is located at the distance between two parallel arrangement of detection planes, which is known. The subpoint that the distance between the bending angle determines, it is known that the known distance between beam and incidence angle detects plane.
