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.
Claims25
A creasing machine comprising:
- a creasing tool,
- a counter element cooperating with the creasing tool,
- a controller to receive data for a new creasing job, 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,
- wherein the at least one 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 at least one creasing projection, and
- wherein the controller determines, based on the received data, (a) if a previously manufactured creasing plate is available in storage and (b), if not, that a new creasing plate is to be manufactured.

A method for creasing a sheet, the method comprising:
- receiving data regarding folding creases to be applied to the sheet,
- determining (a) if a suitable creasing plate is available in an inventory and (b), if not, that a new creasing plate is to be manufactured,
- retrieving, based on the determining, an existing creasing plate from the inventory or manufacturing a new creasing plate by using a punching module for applying a plurality of small deformations to a creasing plate sheet, the deformations constituting at least one creasing projection,
- mounting the creasing plate on a creasing tool, and
- applying folding creases to the sheet advanced through a creasing area between the creasing tool and a counter element.
