Abstract (en)
[origin: EP0020881A1] 1. Method for the production of a book block, in which like layers are each time fed as stacks to a magazine of a series of several magazines arranged one beside the other, the layers of a book block positioned in sequence one after the other are given by the feeder associated with each magazine onto a transport system, which is arranged below or beside the row of magazines parallely thereto, operates continuously or stepwise and which supplies several thread-stitching machines at the same time, collected and thread-stitched, characterized thereby, that the layer of the book blocks previously fed ordered in groups in such a manner in the sequence of the row that l/f groups each of f layers are formed and the layer of a group following one layer is the layer x + l/f, wherein f is the number of the thread-stitching machines and grater than 1, l is the number of the layers and x corresponds to the ordinal number of the layer of the book block, wherein the lowermost layers of the groups following one another along the transport system run through continuously starting from the ordinal number x = 1 up to the ordinal number x = l/f, wherein the quotient l/f is a whole number, preferably an even number, and wherein that layer of a group, which is the same in the sequence, is fed to the same thread-stitching machine each time.
