Abstract: The invention relates to a method and device for producing packs of a food that comes in slices, in particular individually packaged processed cheese slices. The pack of food is put together from two uniform product stacks of food slices. The first product stack is transported via a first feed segment, and the second product stack is transported via a second feed segment, in each case horizontally by means of a transport means at transport speed. The feed segments are guided over one another in parallel in a collection area, and the upper feed segment ends at a sliding edge that defines a collection point, whereby means for synchronization are adjusted such that a product stack that arrives via the sliding edge is neatly placed onto the product stack that is transported to the lower feed segment.
