Abstract
An apparatus for varying a speed of flat products. The apparatus has a first, higher-speed conveyor arrangement containing conveyor drums and belts, and a second, slower speed conveyor configuration containing belt rollers and belts, in which the flat products are each transported between the belts of the first and second conveyor configurations. A pair of rollers with recesses is provided on the circumference in the conveying path of one of the two conveyor configurations). Rotational bodies move about their respective eccentric axes that in turn are located on crankshafts. The crankshafts rotate on axes with reference to the frame walls, and the rotational bodies and the crankshafts move at a constant angular speed omega.
