A sheet turning conveyor.

摘要

A sheet turning conveyor includes a rotary suction drum (26) which comprises suction surfaces (29) and circumferential recesses receiving belts (27), the suction surfaces and the belt surfaces being flush with each other so as to be complementary to the entire drum surface. Each of the suction surfaces is formed with a series of pores (31) arranged along the circumference of the drum and at least two adjacent pores of the suction surface are connected by a groove which allows air to pass between the connected pores.
