During operation of the device, carrier 81 for scanning the control elements 83 on the microswitch 57 is carried by a three-armed lever on the strip 18. The unit 82 is controlled which, for the purpose of executing a pivoting movement of the end face 84 of the label carrier 85, is arranged on a shaft 58 which is arranged on a shaft 58 which, when actuated, is carried by one end through the housing 12 and a control element 83 with interruption of the feed between the guide rollers 25, 26 is located. The other of the rollers 40, 80, the foremost label of the three-armed lever, has an arm 59 on which a guide roller 60 is located in the area of the separating strip, in register with the chain strip, while a device is present.
