  • Patent number: 5918878
    Abstract: A finishing machine is proposed for printed sheets delivered individually in rapid succession by a reproduction machine such as a printing press or a copier. The machine renders possible the manufacture in a production line in a completely automatic manner of brochures, leaflets or booklets without trimming edges. The machine comprises as its main part a station for takeover of the delivered sheets; a device for controlled retardation of the sheets received from the takeover station; a station for horizontal stacking of the retarded stacks; a mechanism for the alignment of the stacked sheets; a device for gripping the stack of aligned sheets a device for pivoting of the gripped stack from a horizontal position to an on-edge position; and a device for encasing the stack in a cover.

  • Patent number: 5836439
    Abstract: To turn through 90.degree. sheets passing at a rapid rate over a roller conveyor in a horizontal plane, a device is proposed which comprises a pair of rollers entrained in rotation at different speeds and spaced apart from each other and from a longitudinal guide on the conveyor transversely with respect thereto. Each of the rollers has its rotation axis inclined with respect to the normal on this guide, by a specified angle which is greater for the roller which is closest to the guide and the rotation speed of which is the smaller. Each of the rollers has its periphery in contact with a support ball or with the lower face of a sheet during its passage, substantially in said transport plane.
