Abstract: A rigid frame hydraulic press that includes a frame on which are mounted a series of movable columns that are used for vertical pressing and an end column that is used for horizontal pressing. The end column has a complementary support in its lower part located between its crossbars. The rear of the end column has opposing cylinders for positional anchoring on multibore plates, while the front of the end column has small transverse cylinders to exert pressure toward the opposite side of the frame. The movable columns have a "U"-shaped structure and a cylinder housed in a grooved guide with a sliding carriage. The cylinder has a fixed end that is attached to the upper part of the column and has a mobile end that is joined to the sliding carriage. The cylinder moves along the length of the inside of the carriage when pressure is applied to it, and the joint of the fixed end is at a given height with respect to the lower end of the column as a function of the length of the cylinder.

Abstract: A press useful for forming furniture such as cabinets includes a determining structure formed by a rectangular frame composed of two vertical columns with as many horizontal cross bars. Incorporated between the two columns are a horizontal and a vertical crosspieces which may be moved by sliding parallel at respective sides of the frame. Each of the mobile cross pieces includes cylinders which are utilized to apply pressure to the work piece.
