Abstract: A book binding machine includes a book block transport system and a plurality of clamps for clamping stacks of leaves. The clamps are disposed at a distance from each other and are guided in guide tracks of a machine frame. The book block transport system includes a clamp, which is also referred to as a lubrication clamp, having a device for lubricating the guide track. An applicator is assigned to each track roller of the clamp, and the lubricant is transferred to the track rollers through the use of a respective applicator such as a brush. The track rollers transfer the lubricant to contact surfaces of the guide track. A lubrication clamp for a book block transport system in a book binding machine, is also provided.

Abstract: To optimize the effort involved when converting a gatherer stitcher which transports initially continuously transported brochures step by step into a stitching station and subsequently into an output station, sensors are assigned to machine components affected by geometrical parameters that are relevant to the process when there is a change of job order and to a reference component. The sensors emit signals defining the phase positions of the machine components, and a controller processing the signals coordinates the phase positions with at least one of the parameters in such a way that the brochures arrive in the output station in a center-oriented manner.
