Method and device for producing defined stacks of folded or unfolded sheets

A method for producing defined stacks of folded and unfolded sheets or sheet-type objects, said method comprising the steps of:

• individually feeding sheets to a horizontal surface;
• placing each sheet on edge onto the horizontal surface;
• separating the sheets into individual stacks with a separating support by forming a first separating plane defining the beginning of the stack and forming a second separating plane defining the end of the stack by sequentially inserting the separating support transverse to the longitudinal extension of the horizontal surface between the sheets placed on edge on the horizontal surface;
• advancing the separating support parallel to the horizontal surface at the stack forming velocity;
• introducing at the first separating plane a first support and at the second separating plane a second support;
• introducing a transferring support at the first separating plane and subsequently at the second separating plane before introducing the first and second supports for maintaining said first and said second separating planes;
• and
• moving said transferring support along said horizontal surface into said first separating plane for transferring the beginning of the stack to said first support and subsequently moving said transferring support into said second separating plane for transferring the end of the stack to said second support.
