A flowing direction regulator and a mould with the same are provided. The fluffing roll is a cylinder with auger flights on one half of the cylindrical surface that direct the cut crop in one direction, and auger flights on the other half of the cylindrical surface that direct cut crop in the direction opposite from the direction of the first half. When the two surfaces are rotationally aligned, the device has the optical effect of a plane plate. At a later point in time, relevant records of the activity log for a particular user can be identified.
