Cut sheet length control in a corrugator dry end
09731927 · 2017-08-15 · ·

Tension spikes in a running web slit to direct output webs to respective upper and lower cutoff knives are minimized by anticipating the increased tension in the web when the lead edge enters an outfeed nip and offsetting the tension spike with a decrease in the force imposed by the infeed pull roll nip, whereby the sum of the web tensions is substantially uniform through the cutting cycle and the sheets are cut to a consistent length.

Material application system

The lower conveyor top is disposed adjacent to the upper conveyor bottom and defines with the upper conveyor bottom a transport path configured to transport a sheet of material in a direction from the first end of the layboy conveyor to the second end of the layboy conveyor. A drive is operably connected to the upper conveyor and to the lower conveyor, and the drive is configured to drive the upper conveyor bottom and the lower conveyor top in the direction. A length of the lower conveyor top is adjustable.

Devices and methods for starting strip material in a substrate processing machine

Systems and methods are disclosed for starting a strip material in a substrate processing machine wherein the machine is not stopped and/or operators do not have to reach into the running machine to start the strip material. Exemplary systems include a strip material guide apparatus including at least one guide arm and at least one gas stream generator configured to direct strip material from the guide arm into a substrate processing machine to join the strip material with one or more running substrates. The gas stream generator is operable to cause a leading end of a strip material dispensed from the guide arm to be conveyed via a gas stream toward the running substrates, such that the leading end of the strip material becomes engaged by the substrate processing machine and the strip material joins with the running substrate.

REEL EDITOR FOR PRE-PRINT PAPER, SHEET, AND BOX MANUFACTURING SYSTEMS
20220204298 · 2022-06-30 ·

Systems for providing efficient manufacturing of paper, sheet, and/or box products of varying size and structure, often with pre-applied print (“pre-print”), are provided herein. Efficient customer ordering/tracking, job aggregation, print imposition, corrugator planning, and tracking and adjustments throughout the manufacturing process are contemplated. A reel editor is configured to edit the roll based on waste and/or errors that occurred during various manufacturing processes (e.g., during printing). A control plan defining what is on each roll of printed web product may be updated after editing. Depending on the configuration, the reel editor may be integrated with various manufacturing components. The reel editor may be configured to determine if there is enough waste on the roll to even making editing worthwhile, such as based on desired quality of the images, customer requirements, different price points, among other possible factors.
