Abstract
In a device for severing endless form sets (14) provided with transverse perforations, having a tear-off arrangement (22) of two transport roller pairs (72 and 74) arranged with spacing from one another it is proposed to drive the two transport roller pairs (72 and 74) at the same transport speed until the transverse perforation next to be torn apart has arrived between the two transport roller pairs (72 and 74). Now the drive speed of the forward roller pair (74) is doubled, which results in tearing open of the transverse perforation. The individual layers of the severed set piece are separated from one another by separator strips (30) and can be conveyed each into allocated reception boxes. The tear-off length desired in each case can be inserted manually into a control apparatus or alternatively, in the case of appropriate marking of the endless form set (14) can be read off with the aid of a detector (202).
