A transport device in a packaging machine includes a plurality of circulating transport chains which each travel over at least one chain wheel. In order to be able to adjust the transport device to differing formats for the bulk product and/or the packaging, the chain wheels can be adjusted with respect to each other in a peripheral direction upon a support shaft. In order to effect as simple and compact a construction as possible, a hydraulic fastening device is provided for fixing the chain wheels relative to each other, wherein the fastening device can be deactivated by means of a releasing device to effect adjustment. The chain wheels can be radially fixed to the shaft by the hydraulic fastening device. It is however also possible for the chain wheels to be disposed on coaxial shaft members which can be adjusted with respect to each other in the peripheral direction and which can be fixed to each other by the hydraulic fastening device.
