Device and method for trimming the top edge, bottom edge and opening edge of a printed product

A method for trimming along a top edge, a bottom edge, and an opening edge of a printed product, comprising:

• providing a synchronously driven conveying device including a conveying rotor having clamps located towards an outside;
• conveying the clamps along a circulating path;
• opening the clamps to an open position at a transfer station;
• loading the printed product into the open clamp at the transfer station;
• closing the clamp to clamp in the printed product;
• conveying the printed product in the closed clamp to a cutting region of a connected cutting unit arranged between the transfer station and a delivery station along the circulating path;
• trimming at least the top and bottom edges of the printed product in the cutting region of the cutting unit, wherein, in the cutting region of the cutting unit, the clamp transitions from a circular control path section into an intermediate control path section in which the clamp maintains a substantially perpendicular position relative to a tangent to a circular cutting path;
• and
• conveying the trimmed printed product to a delivery station, wherein the clamp is opened at the delivery station to allow release of the trimmed printed product.
