A tray loading packaging machine that carries out a method for filling a multi-row packaging tray with piece-form products at a high performance level, having the following steps: dividing up a single-row stream of piece-form products onto a plurality of lanes arranged substantially parallel to one another in order to convey the products further; synchronizing the individual streams of products on the plurality or lanes with one another such that in each case one product from one lane can be transferred to the packaging tray substantially at the same time as in each case one product from the other lanes; and transferring the produces to the packaging tray, wherein in each case one product from one lane is transferred to one row of the packaging tray.
