An apparatus for supplying book blocks includes a feed conveyor to successively transport the book blocks with optional spacing. A buffer conveyor, arranged downstream of the feed conveyor and connected to a control unit, receives a plurality of the book blocks from the feed conveyor and transports them at a first speed, fitting against each other without a gap. A downstream clocking-in conveyor, coupled to the control unit, respectively receives a single book block from the buffer conveyor at the first speed, accelerates and transports the single book block from the first speed to a second speed. A downstream despatch conveyor includes a plurality of spaced apart pushers defining respective gaps between successive pushers. Each book is transported at the second speed toward the despatch conveyor and is inserted into one of the gaps between two successive pushers on the despatch conveyor.

Method and device for clocking in book blocks

A device for feeding a book block, which is formed of at least one printed sheet and transported flat, to a processing station in a clocked manner includes a first and a second transport device. The first transport device has a comb-shaped introduction flap and transport units. The introduction flap includes teeth disposed on a base part and recesses formed between the teeth. The second transport device has a transport duct and a transport finger. The transport duct has a contact surface, a clearance and a gap. The first transport device engages, by the introduction flap, in the clearance. The recesses are open in a direction facing away from the transport duct. The transport units are disposed on a first side of the introduction flap. The introduction flap is connected to a controllable drive and has a pivot axis disposed on a second side of the introduction flap.
