Patent ID: 7134392

Claim:
A conveyor unit for conveying flat objects comprising: a cutter unit; a collection cylinder having a circumferential surface, said collection cylinder being located after, in a direction of travel of the flat objects, said cutter unit; a drive motor for said collection cylinder; a first endless belt extending around a portion of said collection cylinder and cooperating with said collection cylinder circumferential surface and defining a section of a conveying path for conveying the flat objects, having a thickness, in cooperation with said circumferential surface, said first endless belt being driven by frictional contact with said collection cylinder circumferential surface at a transport speed that is automatically adapted to a thickness of the flat objects; a second endless belt and a cooperating third endless belt defining a balance of said conveying path, said second and third endless belts defining a first section of said conveying path, said first conveyor belt and said collection cylinder circumferential surface defining a second section of said conveying path; a drive mechanism for driving both of said second and third endless belts at a controlled speed, said drive mechanism including a frequency-regulated motor independent of said collection cylinder drive motor, said controller speed being matched to said transport speed; and a third endless belt deflection roller and a first endless belt deflection roller positioned directly adjacent each other, said third endless belt deflection roller defining an end of said first section of said conveying path, said first endless belt deflection roller defining a start of said second section of said conveying path.
