A method of processing a blank for forming a construct includes obtaining the blank, the blank including a flexible material and is for being formed into a construct. The method also includes moving the blank in a downstream direction on a first guide and a second guide, and pressing an interior region of the blank with a shaping apparatus in a direction transverse to the machine direction as the blank moves in the downstream direction and as a peripheral region of the blank is engaged by at least one shaping bracket.

A printing device, a printing machine, and a box making machine are provided with printing cylinders on which printing plates can be mounted, ink supply rolls that are placed on the upstream or downstream sides of the printing cylinders in a sheet-conveying direction and that can be in contact with the printing cylinders, ink supply units that can supply ink to the ink supply rolls, first covers that cover the upper parts of the printing cylinders in the vertical direction and that can be opened and closed, and footholds that cover the vertically upper parts of the ink supply rolls and that can be operated by an operator.

A guide position adjustment device includes upstream side guide members and downstream side guide members arranged in order starting from the upstream side in the sheet traveling direction. Each of the upstream side guide members and each of the downstream side guide members are mounted in pairs on the right and left sides of a folder gluer. The guide position adjustment device includes an outlet side guide moving mechanism, which is mounted on a folding guide device provided with a frame moving mechanism for translating, by a first actuator, a supporting frame that supports the upstream side guide members and the downstream side guide members, in the device width direction perpendicular to the sheet traveling direction. The outlet side guide moving mechanism moves, by a second actuator, an outlet side tip end regulation part of the upstream side guide members relative to the supporting frame in the device width direction.

A device for forming a container by folding a cardboard sheet having a lid and notably a tab. The forming device comprising a conveyor driving said cardboard sheet in a direction of travel and a device for folding over said lid. The folding-over device comprises a pressing surface for pressing on said lid, and the pressing surface is configured to move from an initial position toward a deployed position of folding said lid, and vice versa. The said pressing surface is mobile in said direction of travel, and comprises an endless belt motorized in said direction of travel.

An arrangement for cutting paper board sheets. The arrangement includes a first wheel and a second wheel. The first wheel is arranged to rotate around a first axis. The first wheel includes a knife and an element formed as a circular arc with substantially the same radius as the peripheral surface of the first wheel and a corresponding recess formed in the first wheel peripheral surface. The element is pivotally arranged around an axis substantially parallel to the first axis in the recess and the knife is extending from the element such that the position of the knife in relation to the first wheel is adjusted by pivoting the peripheral element by adjustment structure arranged to secure the peripheral element in the desired position. Also, a machine can include the arrangement.
