Claim:
A method for combining with adhesive at least two flat products positioned at least partially one above the other, comprising: moving first flat products in an overlapping flow along a guiding line in a conveying direction; prior to reaching the guiding line, selectively directing an exposed free end of the first flat products one of (a) counter to the conveying direction, wherein the moving includes subsequently dragging the first flat products along the guiding line, and (b) in the conveying direction, wherein the moving includes subsequently pushing the first flat products along the guiding line; separating the first flat products into a non-overlapping flow after leaving the guiding line and while being conveyed through a curved, underneath-arranged conveying region; supplying second flat products in a direction approximately tangential to the curved, underneath-arranged conveying region and from underneath the first flat products with a synchronous time relative to the first flat products, the second flat products each having an adhesive coated surface; and attaching one surface of a respective one of the first flat products along the adhesive covered surface of an underneath supplied respective one of the second flat products if the first flat products are dragged along the guiding line and attaching a surface opposite the one surface of a respective one of the first flat products along the adhesive covered surface of an underneath supplied respective one of the second flat products if the first flat products are pushed along the guiding line.
