Device and method for forming an overlapping stream of under- or overlapping sheets

摘要

The invention relates to a device ( 1 ), in particular a roll-type cross-cutter, for forming an overlapping stream ( 2 ) of underwrapping or overlapping sheets ( 3 ), in particular paper or cardboard sheets, the sheet with a conveying device for conveying the sheets 3 , and with an overlapping device 14 for underlapping or overlapping the sheets 3 in the regions, in particular for the passage of overlapped, joined sheets 3 . having a deceleration device 21 downstream of the overlapping device 14 in the conveying direction X of the sheets for decelerating the overlapping sheets 3 by forming a deceleration interval for 3) have a cross-cutting device 9 upstream of the lap device 14 for cutting the material web 5 into it. According to the invention, the overlapping device 14 is designed to be adjustable in the transport direction X of the sheets 3 and/or on the contrary, independently of the cut length.
