Abstract (en)
[origin: EP1452302A1] The process involves pre-registering gauging abacus in a lower apron containing compensating jacks. A correspondence is established by the abacus between forces measured at level of mounting and pressures applied to the jack for maintaining the lower apron in right position. Pressures resulting from the abacus are applied to the jack according to the measured forces, during a subsequent folding operation. An independent claim is also included for a folding press.
