ABSTRACT:
A continuously working press is provided with a device which adjusts an entry gap in an entry region of a press ram to give the rolling rods of a press a sufficient degree of freedom for self-stabilization. The adjusting device includes an articulated crosshead anchored in said press frame and pivotable about an axis of rotation, a pressure holding plate located within said entry region and adjustable about an axis of rotation and which acts non-positively but resiliently on said rolling rods as they travel through the entry region, and a plurality of hydraulic supporting members located between the articulated crosshead and the pressure holding plate and which are adapted to act on said support device with a pressure profile that increases continuously towards said pressing region.
