A firearm target is formed from a cardboard substrate. A first target is printed on the cardboard substrate. The cardboard substrate is folded into a box shape. The cardboard substrate is cut to form a first flap and a second flap on a first side of the cardboard substrate. The first flap and second flap include notches. The first flap and second flap are folded over with the notches interlocked. The flaps can be oriented to the bottom of the box shape and weighted for stability. A second target can be mounted to the box shape over the first target.

Methods, apparatus, and systems increase converting accuracy and consistency of corrugated articles of manufacture such as blanks, intermediates or converted structures to minimize unintended gap variations, fishtail variations and visual discord as well as to minimize unintentional loss of strength due to conversion of such articles. The constitution of converted articles formed from a corrugated board blanks according to the invention comprises at least one intelligently located score, slit or slot (hereinafter collectively registered modification) based upon knowledge of the corrugated board's fluted medium, including the absolute relative location of at least one fluted medium feature and/or the fluted medium geometry, such as its pitch.

A device for processing a plate element (35) has a rotable hub (52), two tools (57, 58), mounted on the hub (52) to process the element (35) when each tool is in a respective processing position; a drive to rotate the hub (52) and the two tools (57, 58); a rotatable counter-tool (64). The rotation (R) of the hub (52) varies during a rotation cycle of the hub (52), and includes two constant speed phases during each of which one of the two tools (57, 58) is, in succession, in the processing position; and at least one phase with each of the two tools (57, 58) in an intermediate position between the respective processing positions, so as to achieve a front lateral processing position and a rear lateral processing position on the element (35).

A slotter apparatus includes blade-attached slotter heads, receiving slotter heads, a drive device, a movement device, and a control device. The blade-attached slotter heads include slotter knives mounted on outer peripheral portions of the blade-attached slotter heads, are rotatably supported, and are disposed along a sheet transport direction. The receiving slotter heads are rotatably supported, are disposed to face the blade-attached slotter heads, and are disposed in the sheet transport direction in series. The drive device drivingly rotates the several blade-attached slotter heads and the receiving slotter heads. The movement device moves the blade-attached slotter heads and the receiving slotter heads in a rotational axis direction. The control device controls the drive device or the movement device when an adjustment mode in which each of the slotter knives is positioned at a predetermined position set in advance is selected.

The invention is directed to a balanced process for extrusion of a plastic corrugated sheet or blanks, and subsequent converting of the blanks into plastic boxes. The process includes conveying the blanks to a plurality of forming stations for incrementally forming features on the blank needed for forming a box. The present process is performed at a slower speed than typical paper corrugated forming.

A cutting waste removing device, installed in a box making machine for manufacturing corrugated cardboard boxes from a corrugated cardboard sheet, to remove cutting waste generated in a cutting process performed by a paper discharging unit of the box making machine, is provided with an air blowing device which is disposed along a travel region in a device width direction, through which cut processed portions of the corrugated cardboard sheet and the cutting waste travel, and which ejects air toward the cutting waste in such a way as to include a vertically downward directional component in a prescribed ejection mode, and a control device for performing intermittent on-off control of the operation of the air blowing device, wherein the control device controls the air blowing device to be on only at a timing at which the cutting waste passes through an air ejection region of the air blowing device.
