Abstract
Sheets of different formats, i.e. of different format lengths, are transported in a feeding direction one behind the other; and at a certain conveying speed, to at least two collecting drums, which have essentially cylindrical lateral surfaces. Each of these collecting drums is driven about an axis of rotation at a circumferential speed, which corresponds essentially to the feeding speed of the sheets. The first incoming sheet is secured temporarily on one of the collecting drums, while the following, second sheet is secured temporarily on the other collecting drum. At a suitable point in time, the two sheets secured on the collecting drums are detached from the collecting drums and brought together with the third fed sheet to form a sub-product or end product.
