Abstract: A gripper assembly for recovering a layout (22) from a sheet material (12) is presented. It comprises a vacuum gripper (26) with a gripper body (32) on which an array of air flow openings (34a, 34b) is arranged. Air flow openings (34a) associated with one or more blanks (20) of the layout (22) are selectively open and air flow openings (34b) associated to waste (28) of the sheet material (12) are selectively closed. Additionally, an apparatus for recovering a layout (22) from a sheet material (12) comprising such a gripper assembly is described. Furthermore, a method for separating a layout (22) from waste (28) of a sheet material (12) is explained.

Abstract: A creasing machine includes a creasing tool, a counter element cooperating with the creasing tool, and a transportation system for advancing sheets through a creasing area between the creasing tool and the counter element, wherein the creasing tool has a creasing plate provided with at least one creasing projection, and wherein the creasing projection on the creasing plate is constituted by a plurality of small, plastically deformed areas which merge into each other so as to form the creasing projection.

Abstract: The invention relates to a creasing machine having a creasing tool (14, 20, 21), a counter element (22, 23) cooperating with the creasing tool, and a transportation system (10) for advancing sheets (12) through a creasing area between the creasing tool (14, 20, 21) and the counter element (22, 23), the creasing tool having a creasing plate (24) provided with at least one creasing projection (26), characterized in that the creasing projection (26) on the creasing plate is constituted by a plurality of small, plastically deformed areas which merge into each other so as to form the creasing projection (26). The invention also relates to a creasing plate (24) adapted for being used in a creasing machine according to any of the preceding claims, the creasing plate (24) being made from sheet metal and comprising at least one creasing projection (26) formed from a plurality of small, plastically deformed areas which merge into each other so as to form the creasing projection.
