Abstract (en)
[origin: EP0579147A1] Folding and conveying devices are already known in which the fold of the folded sheets (5) does not extend completely across the length or the width of the sheet (5) to be folded, so that there is formed on one side of the folded sheets a loop in each case, into which tongues (25 to 28) can be introduced laterally to allow the folded sheets (5) to be opened again without an overlay fold. According to the invention, the folded sheets (5) are opened while stationary so that sufficient time is available for opening. The folded sheets (5) are opened by means of intervening means such as push-in needles (16) and V-shaped metal opening plates (19), while said sheets are simultaneously adjusted by means of stops (14) and grasped by grippers (18). <IMAGE>
