Embodiment Construction

[0053] exist figure 1 , schematically shows the creasing machine. It comprises a conveyor system 10 for advancing a sheet material 12 through a creasing area 14 in which folding creases can be applied to the sheet material 12 .

[0054] Additional processing stations 16, 18 may be provided as part of or associated with the creasing machine. The processing stations 16, 18 may be used to cut, fold, glue, or otherwise process the sheet 12 or articles produced therefrom.

[0055] The sheet 12 may be made of cardboard, carton or foil, and may subsequently be processed to cut blanks from the sheet to form packages, boxes, bags, envelopes or similar products.

[0056] The sheet material 12 may be supplied to the creasing area 14 individually as shown in the figures or in the form of a continuous web guided through the creasing area 14 .

[0057] It is also possible to integrate a cutting system into the creasing area 14 which allows the individual blanks to be separated from the s...

Abstract

A creasing plate (24) for creasing a sheet (12) of paper, cardboard, carton, foil or similar material, the creasing plate (24) consisting of a plastically deformable material and comprising at least one The indentation protrusion (26), the indentation protrusion (26) is formed by a plurality of small plastically deformed regions which merge with each other to form the indentation protrusion (26).

Description

technical field [0001] The invention relates to a creasing plate for creasing sheets of paper, cardboard, carton, foil or similar material. Background technique [0002] A creasing machine is used to create one or more indentations in a sheet, from which a folded blank is cut. Each indentation forms a sort of "hinge" that allows the later-formed blank to fold at well-defined locations. [0003] A creasing machine can be formed as a device or system, which can be a stand-alone unit or integrated into a larger machine or system such as a printing press or a finishing machine. [0004] Sheets can be made of cardboard, carton or foil, and they can be supplied to the creasing machine individually or in a continuous manner as part of a web. [0005] Indentations are made by locally applying pressure on the sheet. For this purpose, it is known that a creasing knife presses on the surface of the sheet to produce the creasing. It is also known to provide local protrusions on the ...
