Method and apparatus for accurately manipulating a sheet
First Claim
1. A method for accurately manipulating at least one sheet, comprising:
- in a first time interval, accelerating or decelerating said at least one sheet, another sheet or a holder or receiving a sheet;
measuring at least one quantity which forms a measure for said deceleration or acceleration in said first time interval;
registering at least one measuring result obtained upon measuring; and
subsequently determining in accordance with said registered measuring result a moment at which an acceleration or deceleration of said at least one sheet in a second time interval after said first time intervals started.

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.

12. An apparatus for accurately manipulating at least one sheet, comprising:
-
means for at least accelerating or decelerating at least one sheet;
at least one measuring means for measuring at least one quantity which forms a measure for the deceleration or acceleration of said at least one sheet;
a control means for operating said means for at least accelerating or decelerating at least one sheet;
wherein said control means is arranged for obtaining in cooperation with said at least one measuring means at least one measuring result which represents a deceleration or acceleration of said at least one sheet within a first time interval, for registering said measuring result and for determining, in accordance with said registered measuring result, a moment at which an acceleration or deceleration in a second time interval is started. - View Dependent Claims (13)
