ABSTRACT:
The transport device (10, 10a) for web-shaped recording substrates (3, 3a, 3b) includes transport devices (13, 13a, 15, 15a, 15b) driven by an electromotor, wherein the transport devices (13, 13a, 15, 15a, 15b) transport back and forth and asynchronously the recording substrate (3, 3a, 3b) from a starting position (IP, IP1, SP, SP1) to a target position (PP, PP1, TP, TP1). A gear coupling (16, 16a, 16b) is in addition coordinated to the transport devices (13, 13a, 15, 15a, 15b), wherein the gear coupling (16, 16a, 16b) controls automatically the tension of the recording substrate (3, 3a, 3b) tensioned between the transport devices (13, 13a, 15, 15a, 15b). In addition, the transport device (15, 15a, 15b) can be disengaged from the electromotor drive (11, 11a) by actuating an operating lever (19, 19a), wherein the operating lever (19, 19a) engages the gear coupling (16, 16a, 16b), when sheet-shaped recording substrates (2, 2a, 2b) are to be transported in addition to the web-shaped recording substrates (3, 3a, 3b) in the printing device (1, 1a).
