Abstract
A conveyor unit for conveying a web of material, in particular for conveying a web of corrugated board in a corrugating machine, comprises a machine frame; a delivery roller, which is lodged in the machine frame rotatably about a first axis of rotation; a drive for actuation of the delivery roller; a draw roller, which is lodged in the machine frame rotatably about a second axis of rotation, the first axis of rotation and the second axis of rotation being substantially parallel to each other, a nip for the web of material to pass through being formed between the delivery roller and the draw roller, the draw roller having a draw-roller-surface coefficient of friction which is selected so as to ensure power transmission from the draw roller to the web of material that rests thereon, and the delivery roller having a delivery-roller-surface coefficient of friction which is less than or equal to the draw-roller-surface coefficient of friction; and a torque transmission arrangement, which acts between the delivery roller and the draw roller for transmission of torque from the delivery roller to the draw roller, a free-wheel being disposed between the torque transmission arrangement and the draw roller.
