Disclosed is a corrugated paperboard box making machine 1 in which a slotter device 6 comprises: a first slotter unit 61 comprising a first slotter 610, a first stationary blade 612 and a first displaceable blade 613; and a second slotter unit 62 comprising a second slotter 620, a second stationary blade 622 and a second displaceable blade 623. A control device 100 is operable to switch the slotter device 6 between a first production mode and a second production mode. Specifically, the control device 100 is operable, when implementing the second production mode, to acquire and store a total blade length of the first stationary blade 612 and the first displaceable blade 613 and a total blade length of the second stationary blade 622 and the second displaceable blade 623, and perform positioning control for the slotter blades, based on the stored total blade lengths.

A precut module with one or more profiling heads and/or circular saws may be provided upstream of a saw module. The precut module may be used to implement a portion of a cut that would otherwise be made by the saw module, thereby reducing the depth of cut required at the saw module. In some embodiments, profiling heads may be used to profile a block that is wider than a desired side board. The block may be cut from the workpiece and sent to the edger. This may provide the same or better wood volume recovery and/or throughput speed than profiling the side board or cutting the side board from a flitch. In some embodiments, cut patterns for the precut module and other machine centers may be calculated and/or selected based on a desired depth of cut at the saw module, desired throughput speed, wood volume recovery, and/or other parameters.

Methods of separating discrete articles from continuous webs are disclosed. The methods use a separation assembly. The present disclosure further includes a cutting assembly and a pair of cutting rolls for use in the separation assembly.

A sheet processing apparatus (1) includes a first processing section (1000), a second processing section (2000), and a third processing section (3000) arranged on a straight line, and conveys a sheet (4200) therebetween. The first processing section (1000) forms a plurality of first processing lines extending in a first direction (an X axial direction) on the sheet (4200), by moving a plurality of tools (1110-1260) to the first direction in relation to the sheet (4200). The second processing section (2000) forms a plurality of second processing lines to a second direction (a Y axial direction) orthogonal to the first direction on the sheet (4200), by moving a plurality of tools to the second direction in relation to the sheet (4200). The third processing section (3000) forms a third processing line (aslant line, curve line) on the sheet, by relatively moving the sheet (4200) and the tool (3110, 3120).

In an ingot cutting apparatus that cuts an ingot using a plurality of stretched wires, load sensors are provided on the new wire side and the old wire side of the ingot, and loads applied to the new wire side and the old wire side of the ingot are measured using the load sensors on the new wire side and the old wire side. When measuring the loads, for example, the center of moment about the X-axis that is the running direction of the wire is calculated. When the deviation from the center of gravity of the ingot is greater than or equal to a reference value, notification for replacement of the wire, control of the conveying speed of the wire, control of the pressing speed of the ingot, and so forth are performed through a control unit.

Embodiments of a system and a method for manufacturing a gypsum board can be used to produce a gypsum board having at least one perforated cover sheet via a cover sheet perforator system. The cover sheet perforator system can include a perforator roller is disposed downstream of a forming station along a machine direction, a roller support frame for rotatably supporting the perforator roller such that its rotational axis extends along the cross-machine direction, and a motor arranged with the perforator roller to rotate the perforator roller about the rotational axis. The drive motor can be adapted to rotate the perforator roller with a tangential speed substantially equal to the line speed to produce a series of perforation holes in an upwardly-facing cover sheet as the gypsum board moves past the perforator roller.

A device for carrying out cutting operations on an unbound formatting edge of a printed product includes a cutter to carry out edge-related cutting operations. A transporter transports the printed product from a first cutting location, at which the first cutting operation for a first formatting edge of the printed product takes place, to a second cutting location, at which a second one of the cutting operations for a second formatting edge takes place, and to a third cutting location, at which a third one of the cutting operations for a third formatting edge is carried out. The transport of the printed product from one cutting location to the next is carried out along a guide section. The transporter includes a gripper with which the printed product is gripped by the spine and conveyable from one cutting location to the next in a suspended manner.
