Abstract

To pull apart interfolded, imbricated paper copy products (4, 5), two pairs (1, 2) of upper and lower transport systems, typically sprocket chains, each have engagement projection elements (10-13), preferably roller elements, extending therefrom, and gripping laterally projecting edges of the respective imbricated in-folded copy products. The paths of the upper and lower transport systems (6-7, 8-9) converge towards each other to grip the copy products and, after having gripped the copy products, the pairs diverge laterally from each other to pull out and pull apart the copy products (4', 5') gripped by the respective pairs of the transport systems, the upper and lower transport systems then diverging to release the copy products to further removal transport arrangements, for example transport belts (17, 18).
