Apparatus for transporting a printing material sheet

An apparatus for transporting a printing material sheet, comprising:

• a holding crossmember for holding the printing material sheet, said holding crossmember being a sheet gripper bar having first and second ends;
• a traveling-wave motor operatively associated with said crossmember for driving said holding crossmember, said traveling-wave motor having a first traveler and a second traveler for mounting said holding crossmember;
• and
• a spring suspension movably mounting said holding crossmember to said first and second travelers, said holding crossmember being connected articulatedly to said first traveler at said first end and being connected articulatedly to said second traveler at said second end.

In combination with a printing machine for processing printing material sheets, an apparatus for transporting a printing material sheet comprising:

• a holding crossmember for holding the printing material sheet;
