Moving, first roller pair of the upper pressure, which is lowered by the machine control and stops the feed of the next workpiece until the necessary distance to the preceding workpiece is reached.

With the help of this roller pair, the next workpiece can already be held in starting position and can be fed immediately after it is released by the machine. Thus, without extensive mechanization, shortest workpiece distances are reached.
