1. A stacker wheel comprising sheet pockets distributed over the circumference for receiving one or several sheets of sheet material, which extend in the stacker wheel from radially outside to radially inside, wherein each of the sheet pockets is formed by a first surface facing a second surface, and both the first surface and the second surface of each of the sheet pockets have a wavy course of the sheet pockets, viewed along the respective sheet pocket from radially outside to radially inside, both the first surface and the second surface each having a first curvature, in particular a positive curvature, in a first section and a first inflection point between the first section and a second section adjacent thereto, and wherein the first inflection point of both the first surface and the second surface, viewed along the respective sheet pocket from radially outside to radially inside, lies in a region of 40% to 70% of the length of the respective sheet pocket, and wherein the sheet pockets are so constituted that the width of the respective sheet pocket, viewed from radially outside to radially inside, consistently decreases or remains the same, but, viewed from radially outside to radially inside, at no point of the sheet pocket increases.
