A silicone rubber coating 54 is positioned upon the lower gripping member 38. The hme 37 is connected to a pair of gripper ends 44 and 45. The belts 20 are respectively connected to the gripper ends 44 and 45 by a pair of pins 56. The belts 20 are connected to the sheet gripper 26 behind the leading edge of the sheet 12 relative to the forward direction of movement of the belts, as indicated by arrow 14, when sheet 12 is being transported by sheet transport apparatus 10. The sheet gripper 26 is driven by the belts 20 at the locations where the s...
