ABSTRACT:
Folded products, supplied in dual-comb like interdigited form are transported by a transport chain system (75) carrying grippers (84, 85) in a vertical direction to form a vertical stack. Grippers engage alternate products about their fold line, and hold the interdigited intermediate sheets therebetween. The transport system and a carrier structure are placed in relative positions to permit the grippers of the transport system to pick up the products (1, 2) at the fold line and, after reorienting the products, to place them in a vertical stack on a support (96, 110), a cam track (88) opening the grippers on the transport system (75) as the grippers pass about a vertically movable deflection wheel (97) to release the products. The deflection wheel moves upwardly as the stack grows. The products are originally supplied in open V-shaped form, and one group (2) of the products is gripped at the open edges of the V, as well as at the fold lines; as so gripped it is inverted and transported to fit, roof-like, over the other products (1) which retain their open V position, for example by guiding a pair of clamping strips or rails (35, 35') with grippers (40, 41) thereon in a circular path.
