    摘要: A method and arrangement for identifying and finding the grippers of a gripping conveyor used to transport printed products. The gripping conveyor is divided into a number of sections wherein the length of each section is sufficiently short to enable length variations of the section to be avoided in operation. A group of grippers at the end of each section form an identification code for the following section. The code may be compiled by virtue of each gripper in the group either carrying or not carrying a marker, such that the grippers will form a binary code. The gripper located before the code may carry a marker which indicates the beginning of the code and the beginning of the following section. A sensor senses the code and thereby finds the section of interest. A given gripper within the section can then be found by its position in the section. A gripper counter which senses the serial number of the gripper in the section may also be used.
