• and
• at least one movement control assembly per drive member, the movement control assembly being connected to the motor and at least one drive member, for providing a movement control of the respective drive member relative to the frame;
• wherein
• the movement control assembly is suitable for imparting a path of movement to a coupled drive member, the path of movement comprising a closed cycle, which closed cycle is a resultant of at least two guide tracks comprised by the movement control assembly;
• the path of movement comprises a drive path and a return path wherein the return path does not cross the drive path, with the path of movement a linear movement along the drive path and a curved movement along the return path;
