Abstract: For accurately manipulating a sheet, in accelerating or decelerating that sheet, another sheet or a holder for receiving a sheet in a first time interval, a quantity is measured which forms a measure for the deceleration or acceleration in the first time interval. A measuring result obtained upon measurement is required. Next, a moment at which an acceleration or deceleration of the sheet in a second time interval after said first time interval is started is determined in accordance with the registered measuring result. As a result, in a very simple manner, an accurate determination is obtained of the moment at which the intended acceleration or deceleration is to be started. Further disclosed are apparatuses for practicing the proposed method.
