Abstract (en)
[origin: WO9103371A1] The folding press is comprised of an upper table (1) and a lower table (2), the lower table having compensation cylinders (3) intended to remedy the defects inherent to the folding process. The press-folder includes an automatic device for comparing the flexion of each of the tables. Said device has two longitudinal bars (4, 5) arranged respectively within longitudinal housings (6, 7) of each of upper and lower tables. One of the extremities of each bar is fixed by fixing means (14, 15) to the extremity of its respective housing. The other extremities of each of the bars are respectively connected to linear inductive sensors (9, 10) secured respectively to each of the tables and connected to a digital control (11) which compares the signals from both sensors and to program automatically the actuation of the compensation cylinders till the flexion difference of the upper and lower tables has been compensated.
