A sheet processing apparatus includes: at least one processing tool that takes a processable state and an unprocessable state; a setting unit that sets operation parameters on the processable state and the unprocessable state; and a control unit that controls an operation of the processing tool based on the set operation parameters, in which the setting unit sets the operation parameters such that: a processable state holding process in which the processing tool holds the processable state, is executed, when a certain portion-to-be-processed is formed in a certain pre-product and then a next portion-to-be-processed of the same type as the certain portion-to-be-processed is formed in a next pre-product; and/or a processing tool selection process in which the processing tool for forming the portion-to-be-processed is selected so that a moving distance of the processing tool is minimized, is executed.

A package is provided, comprising a packaging material having a bulk layer and being formed into a three-dimensional container by folding the packaging material along predefined crease lines thus forming a fracture along the crease lines. The package comprises a plurality of corners, wherein at least one of the corners is arranged at an area of the packaging material in which two or more crease lines intersect.

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. Further, the invention relates to a method for creasing sheets (12), in particular made from paper, cardboard or foil, comprising the following steps: data regarding folding creases (30) to be applied to the sheet (12) is provided. A control (60) determines if a suitable creasing plate (24) is available in an inventory or if a new creasing plate (24) is to be manufactured. Based on the determination of the control (60), either an existing creasing plate (24) is retrieved from the inventory (62) or a new creasing plate (24) is manufactured by using a punching module (40) for applying a plurality of small deformations to a creasing plate blank (24), the deformations constituting at least one creasing projection (26). The creasing plate (24) is mounted on a creasing tool (20, 21), and the creasing tool (20, 21) cooperates with a counter element (22, 23) for applying folding creases (30) to sheets (12) advanced through a creasing area between the creasing tool (20, 21) and the counter element (22, 23).
