Abstract

An apparatus for the manufacturing of work pieces using pressure, such as bending, punching etc, said apparatus in principle compriving a surface (2), an adjustable carrier (3) regarding the surface, for a thereon affixed pressure device such as a hydraulic cylinder, said carrier (3) is adapted to be pivoted about an axis (A-A) parallel to said surface crossing the pressure axis (B-B) of the pressure device, whereby the pressure device can be placed at any desired angle in relation to the table, especially in a first position wherein the pressure line (B-B) is vertically to said surface, and in a second position wherein it runs parallel to it, such that the work pieces can be extended beyond the pivoting support within the working area of the pressure device.
