Patent ID: 8127673

Claim:
An inverter for turning a sheet traveling along a transport path in a printing machine, comprising: a) two entrance rollers oriented essentially parallel to each other and arranged to form an entrance nip; b) a plurality of deflecting rollers arranged along the transport path after the entrance rollers, the deflecting rollers not oriented essentially parallel to each other; c) two exit rollers oriented essentially parallel to each other and arranged to form an exit nip, the exit rollers being arranged along the transport path after the deflecting rollers; d) a guide roller oriented essentially parallel to the entrance rollers or the exit rollers; and e) a web-shaped clamping belt entrained around both entrance rollers, the deflecting rollers, both exit rollers, and the guide roller so that: the clamping belt passes twice through the entrance nip and twice through the exit nip to define two clamping belt segments that face each other and move together from the entrance nip to the exit nip and two returning belt segments that move from the exit nip to the entrance nip; the sheet entering the entrance nip is gripped between the clamping belt segments and transported by the clamping belt segments through the deflecting rollers to the exit nip; and the sheet is turned 180° around the direction of travel of the sheet while the sheet is transported.
