  • Patent number: 6632059
    Abstract: In a method for adhesive attachment of a cover and a binding strip on the flanks of a spine of an book block comprised of bound printed sheets, the book block is transported in a transport direction on a circulating transport device. A binding strip is placed onto the book block spine such that lateral strip parts project laterally past the spine. The cover is moved into a proper position relative to the book block spine in accordance with the cycle of the book block and in the transport direction of the book block. At least one of the lateral strip parts is loaded on a side facing away from the cover with a pressing element. The cover and the book block pass through a pressing device in order to connect the cover and the book block to one another.

  • Patent number: 6077016
    Abstract: An apparatus for roughening a surface of a book block spine formed of a plurality of individual printed sheets clamped together. The apparatus includes a roughening tool which has a tool bit holder having a rotary axis and a radial face; a plurality of cutter tool bits mounted in a circular array on the tool bit holder and projecting axially from the radial face and together defining a cutting plane; and a drive for rotating the tool bit holder about the rotary axis. The apparatus further includes an arrangement for effecting a relative movement between the book block spine and the roughening tool in a direction of displacement; and an arrangement for setting the roughening tool relative to the book block spine such that the cutting plane forms an acute angle with the direction of displacement, whereby arcuate markings cut simultaneously into the surface of the book block spine along diametrically opposite portions of the circular array have unlike depths.
