A sheet drying device and method, and a box making machine, wherein provided are: a heating lamp (111) that is disposed facing a printing face of a cardboard sheet (S); a voltage adjusting unit (122) that adjusts the voltage of electrical power supplied to the heating lamp (111); a voltage setting unit (121) that sets the working voltage of the heating lamp (111) by increasing or decreasing a reference voltage according to the thickness of a water-based paint on the cardboard sheet (S), where the reference voltage is a voltage that is less than the rated voltage of the heating lamp (111) by a preset prescribed value; and a controlling device (101) that changes the voltage of the heating lamp (111) to the working voltage set by the voltage setting unit (121) using the voltage adjusting unit (122).

A bale of stock packaging material includes a continuous tube of paperboard material, the continuous tube of paperboard material being flattened and folded back and forth on itself into a fan-folded bale. The continuous tube of paperboard can be a single piece of paperboard with two opposed edges that are folded to overlap with each other. The paperboard material can include a corrugated layer. The opposed edges can be adhered together to form a single seam that runs lengthwise along the continuous tube of paperboard. The adhesive can be applied between the two edges which can join to form the single seam.

The present invention provides a sheet stacking device, a counter-ejector, and a carton former and is provided with: a hopper unit that stacks cardboard boxes; feed rollers that feed a cardboard box to the hopper unit; a first blower device that blows air from above the hopper unit toward the cardboard box fed by the feed rollers; and a second blower device that blows air between the cardboard box stacked in the hopper unit and the cardboard box fed by the feed roller.
