An automatic feed device for individual publishing products of different thickness and sizes includes a first conveyor belt (13) and a second conveyor belt (14) arranged with the first conveyor belt (13) being partially over the second conveyor belt (14) in combination with an automatic feed device having a bearing structure (15), a pair of manipulator members (19) for gripping the publishing products (12) on the first conveyor belt (13). The publishing products are then laid down on the second conveyor belt (14) separate from one another while the manipulators (19) alternately move forwards and backwards between the first and second conveyor belt (13, 14) to transfer the individual publishing products to two predetermined positions on the first and second conveyor belts (13, 14).
