The invention relates to a synchronous flat belt drive, wherein at least one series arrangement of projections (210) has a purely rolling engagement with a series arrangement of apertures on a flat belt (100). The flat belt (100) supports on a pulley (300) only radially, and on a rotation member (200) only tangentially. The generatrix of the series arrangement of apertures is the rolling of a pulley working surface cylinder with projecting projections (210) of a rotation member (200) formed as a face gear. The flat belt (100) is formed of at least a single strip in a layer arrangement of at least one layer, wherein the ends of the individual strips are variously arranged in a layer. An individual strip forms also several layers and is also as an endless strip part of a layer arrangement.
