1. A method for operating a first machine of a manufacturing process section arranged to carry out a production cycle, said production cycle comprising a pressing part and a non-pressing part, which said first machine is operated in conjunction with at least one second machine and which said first machine carries out a process during a working part of the production cycle on a workpiece which is loaded into and/or unloaded out of said first machine by said at least one second machine during a non-working part of each process cycle, the method comprising:

  • synchronizing said first machine to said second machine dependent on a speed or position of said second machine by adaptively controlling a speed of said first machine to decelerate said first machine at a point before a start point after which unloading is permitted; and

    synchronizing the speed of said first machine to said second machine by controlling the speed of said first machine and by decelerating said first machine at a start point before an estimated time at which said first machine shall reach the beginning of the unloading point stage towards zero speed and accelerating said first machine to reach an end point of a loading stage at a highest possible speed.
