ABSTRACT:
The transporting apparatus has a guide which forms a closed loop and in which transporting members circulate. The transporting members are driven at the beginning and end of the effective conveying zone by in each case an independently controllable drive mechanism. Between successive transporting members there are in each case spring elements, which are designed exclusively for the transfer of compressive force. The drive means of the drive mechanisms driving the transporting members are preceded by controlled blockers, by which the transporting members are prevented from being taken along by the drive. As a result it is ensured that each transporting member seizes a printing product, even if there are gaps in the printing products as they are fed to the transporting members, the printing products preferably being fed in imbricated formation. At the delivery point, the delivery of printing products may also be delayed by one or more cycles without stopping the drive. The spring elements allow a differing number of transporting members to be located between the drive mechanisms.
