Abstract
A conveyor unit for conveying flat objects includes at least first, second and third endless belts, together with a cylinder.

The second and third belts define another section of the path of conveyance.
Claims14
A conveyor unit for conveying flat objects comprising:
- a collection cylinder having a circumferential surface, said collection cylinder being located after, in a direction of object travel, a cutter unit;
- 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;
- a second endless belt and a cooperating third endless belt defining a balance of said conveying path, said first and third endless belts defining a first side of said conveying path, said second conveyor belt and said collection cylinder circumferential surface defining a second side of said conveying path;
- a drive mechanism, adapted to be controlled independently of a rotating speed of said collection cylinder, and driving said second and third endless belts;
- and
- a regulating device adapted to control a speed of said second and third endless belts drive mechanism and wherein speeds of said second and third endless belts, with respect to said rotating speed of said collection cylinder, are regulated by using a variable proportionality factor based on the thickness of the flat objects being conveyed in said regulating device.
