Claim:
A method of producing perfect-bound printed products formed from several printed products, the method comprising feeding the printed products, which are gathered to form loose book blocks, by means of feeders, which are arranged along a gathering line and are driven at least approximately with synchronous timing, to a conveyance device, the conveyance device having receiving devices that follow one another at regular intervals and are guided on a closed revolving track, and transferring the printed products by this conveyance device into a gluing machine, wherein a switchable deflector is installed in a transfer zone between the conveyance device and the gluing machine wherein, in the event of an interruption of a processing operation, the gluing machine, arranged downstream of the conveyance device and having a conveying function, continues to operate at least until a last printed product in the gluing machine is finished, further comprising, while the gluing machine is emptying, stopping further feeding of printed products to the receiving devices of the conveyance device and further feeding of loose book blocks to the gluing machine, wherein during the interruption of the processing operation the book blocks at a beginning of a transfer zone are no longer deflected by a deflector toward the gluing machine.
