Abstract
The present invention relates to a folding device in a corrugated cardboard box making machine which is capable of adapting to a thickness of a corrugated cardboard sheet by regulating a space between a folding belt and an upper guide, and also capable of accurately making folding width of the corrugated cardboard sheet by regulating the position of a gauge belt. Having main transporting means for simultaneously positioning the folding belt, upper guide and gauge belt, the device is provided with an upper guide transporting means for independently regulating the position of the upper guide and a gauge belt transporting means for independently regulating the position of the gauge belt. The device is further provided with a control means for controlling the drive means and the gauge belt transporting of the upper guide transporting means.
