Abstract
Process for bending a plate (1) of press-formable material, comprising the use of a blank-holder means (4) to firmly hold the plate on its horizontal plane between said blank-holder means and an appropriate anvil (2), and the subsequent actuation of a knife-shaped tool (11) to perform the bending operation, in which said actuation of said knife-shaped tool (11) consists of a first purely translational movement and a second purely rotational movement, wherein said first purely translational movement brings about a first bending by a 90 DEG -angle of the edge portion of the plate to be bent, and said second purely rotational movement is effective in increasing the bending angle to any greater angle than 90 DEG . <IMAGE>
