Abstract
This device for bending the tool holder of a folding press comprises structure for controlling the deformation of the wedge secured at either end, in the form of a hollow screw engaged in a socket rigid with the tool holder so that it can accomplish movements of translation within this socket, a member for fastening the screw to the wedge, a sprocket mounted coaxially to the screw on the screw-threaded shank thereof for causing the translation of the screw in the socket, and a single driving system for controlling the rotation of the set of sprockets acting at different thrust points disposed at spaced intervals along the wedge, this single wedge having a relatively great length and being therefore easily deformable under the control of the single control system.
