ABSTRACT:
A transport device for transporting sheet elements into a folder-gluer comprising two longitudinal support structures between which there extend one or more movement slides, one or more lead screws and a drive shaft for a belt. At least one longitudinal member supports at least one endless conveyor belt driven by the shaft. The longitudinal member is mounted in sliding connection on the movement slides and on the drive shaft and is in helical connection with the lead screws. A protecting device over the drive shaft blocks user access to the shaft. It is illustrated as a profile over the shaft and slide. The protecting device transversely connects the two longitudinal support structures.
