An edge-cutting device performs edge-cutting for cutting away trimmings of a corrugated cardboard sheet toward the front and back when switching between orders is to be performed in a corrugating machine. This edge-cutting device has an edge-cutting knife provided to project from the outer circumference of a cylinder having an axis disposed in the width direction of the corrugating machine; and a control device that, when switching between orders is to be performed, controls the edge-cutting device to perform a first edge-cutting process for edge-cutting trimming of an old order at the first rotation of the edge-cutting knife and a second edge-cutting process for edge-cutting trimming of a new order at the second rotation. The control device includes a calculation device for calculating the order switching time, and a variable control device for variably controlling the time interval between the first edge-cutting process and the second edge-cutting process.
An edge-cutting device that performs edge cutting for cutting away a trim of a cardboard sheet forward and backward in a case where an order is changed in a corrugating machine, the edge-cutting device comprising:
