Abstract

The invention has to do with conveying systems for folded products coming from a folder and each made up of sheets which are overlapped so that their unoverlapped edges are sticking out sideways. For pulling the overlapped sheets out sideways and separating them, the apparatus has two gripping means moving along the sides of the system, each gripping means having a gripping gap for taking up said edges. One gripping means is placed at an angle to the direction of conveying for pulling the sheets out to the side. The gripping means are made up of belts or pulleys running at an equal speed and with a gap between them for the edges. One useful effect of the apparatus is that it is not necessary to keep to any fixed spacing between the products in their direction of transport.
