The blank defines a starting plane. The pleating machine includes a first blade pair and a second blade pair. The first blade pair is configured to anchor the blank at a first location of the blank and the second blade pair is configured to anchor the blank at a second location of the blank. The first blade pair moves vertically with respect to the starting plane during a corrugation operation, and the second blade pair is constrained to move within the starting plane during the corrugation operation. The first blade pair and the second blade pair move cooperatively to form a corrugation in the blank. ## Claims ### Claim 1 A pleating machine, comprising: a first blade pair configured to anchor a blank at a first location of the blank, the blank defining a starting plane, wherein the first blade pair is configured to move vertically with respect to the starting plane during a corrugation operation; a second blade pair configured to anchor the blank at a second location of the blank and constrained to move within the starting plane during the corrugation operation, wherein the first blade pair and the second blade pair move cooperatively along a length of the starting plane to form a corrugation in the blank during the corrugation operation; a fixed stop; and a movable stop configured to move toward the fixed stop during the corrugation operation. ### Claim 2 (depends on 1) The pleating machine of claim 1, wherein the first blade pair is further configured to move along the length of the starting plane during the corrugation operation. ### Claim 3 (depends on 1) The pleating machine of claim 1, wherein the first blade pair comprises a first upper blade and a first lower blade on opposite sides of the blank and configured to move vertically in opposing directions to clamp the blank at the first location during an anchoring operation and to move in the same direction during the corrugation operation. ### Claim 4 (depends on 3) The pleating machine of claim 3, wherein the second blade pair comprises a second upper blade and a second lower blade configured to move in opposing vertical directions to clamp the blank at the second location during the anchoring operation. ### Claim 5 (depends on 1) The pleating machine of claim 1, further comprising a pivot assembly connecting the first blade pair to the second blade pair. ### Claim 6 (depends on 5) The pleating machine of claim 5, wherein the first blade pair and the second blade pair form a blade cycle and a plurality of blade cycles extend along the length of the blank, wherein the pivot assembly connects the plurality of blade cycles to maintain equal forces across the plurality of blade cycles. ### Claim 7 (depends on 6) The pleating machine of claim 6, wherein the pivot assembly allows for consistent retracting of the blade pairs to a selected position for receiving a blank for a subsequent corrugation operation. ### Claim 8 (depends on 1) The pleating machine of claim 1, further comprising a lengthwise actuator configured to move the movable stop and vertical actuators to move the first blade pair and the second blade pair. ### Claim 9 A method of corrugating a blank, comprising: anchoring the blank at a first location via a first blade pair and at a second location via a second blade pair, the blank defining a starting plane and disposed between a fixed stop and a movable stop; moving the first blade pair vertically out of the starting plane to corrugate the blank at the first location during a corrugation operation; moving the second blade pair along a length of the starting plane and within the starting plane to corrugate the blank at the second location; and moving the movable stop toward the fixed stop as the blank is being corrugated. ### Claim 10 (depends on 9) The method of claim 9, further comprising moving the first blade pair along the length of the starting plane during the corrugation operation. ### Claim 11 (depends on 9) The method of claim 9, wherein the first blade pair comprises a first upper blade and a first lower blade on opposite sides of the blank, further comprising anchoring the blank at the first location by moving the first upper blade and the first lower blade in opposing vertical directions to clamp the blank at the first location and corrugating the blank by moving the first upper blade and the first lower blade in the same horizontal direction. ### Claim 12 (depends on 11) The method of claim 11, wherein the second blade pair comprises a second upper blade and a second lower blade, further comprising anchoring the blank at the second location by moving the second upper blade and the second lower blade in opposing vertical directions to clamp the blank at the second location. ### Claim 13 (depends on 9) The method of claim 9, further comprising maintaining a distance between the first blade pair and the second blade pair via a pivot assembly connecting the first blade pair to the second blade pair. ### Claim 14 (depends on 13) The method of claim 13, wherein the pivot assembly includes a first pivot arm having a first end and a second pivot arm having a second end, wherein the first end is rotatably coupled to the second end.
