In a photogravure rotary machine, each side of the form cylinder is mounted in a bearing housing, which is secured in a saddle portion of a carriage provided with a sleeve drive. The carriage is displaceably mounted on a guide secured on a machine wall and which carries a pivotally mounted retaining fork for the bearing housing. A locking mechanism is provided for locking the carriage in its operating positon, which is in an operative connection with a switching element that is electrically connected to a machine control. In the range of the extended position of the carriage is arranged an incline with a hinged return feed ratchet for lifting the form cylinder on the machine wall.
