Patent ID: 8091879

Claim:
A conveying device for interaction with a cutting unit having a cutting region for trimming one of a top edge, bottom edge and opening edge of a printed product, the conveying device comprising: a conveying rotor for being synchronously driven with the cutting unit for transporting the printed product through the cutting region of the cutting unit, the conveying rotor having outwardly protruding clamps for being guided on a circulating path sequentially past a transfer station for being loaded with the printed product, past the cutting region of the cutting unit and past a delivery station for delivering the printed product in an open position, the conveying rotor being operable for closing the clamps and clamping in the printed product when the printed product is moved in a controlled manner into the cutting region of the cutting unit for trimming, wherein the conveying rotor includes: a bearing block adapted to be fixedly connected to a machine frame; and at least one rotor disc mounted on the bearing block and arranged to rotate about a rotational axis, wherein each clamp is fastened on a circumference of the at least one rotor disc to be pivotable about pivot axes arranged parallel to the rotational axis of the rotor disc, and wherein an outermost edge of each clamp is constructed to be at a distance from a cutting path of the cutting unit during trimming of the printed product, wherein each clamp comprises first and second clamp parts, wherein the first clamp part trails the second clamp part in a circulating direction of the conveying rotor, and wherein an outer edge of the first clamp part is offset inwardly with respect to an outer edge of the clamping plate of the second clamp part.
