Abstract
An apparatus for producing printed products such as books, magazines, brochures, catalogues or the like comprises several connected devices for the processing of printed sheets. The printed sheets are admitted with blast air via at least one air supply in order to change or maintain their position. At least two of the connected devices are respectively provided with at least one blower for generating blast air. The blast air can be used in the respective device. The blowers are connected to a control unit of the apparatus so that the blast air generated by the blowers can be controlled as needed.
Claims28
An apparatus for producing printed products, such as books, magazines, brochures, catalogues or the like, comprising:
- a plurality of connected devices for processing printed sheets, wherein the printed sheets have an upper side and are supported from underneath in the connected devices;
- a plurality of air supplies each dedicated to a respective one of the plurality of connected devices, each air supply including at least one blower that generates blast air, a distribution channel receiving the blast air from the at least one blower and at least two spaced apart blast-pipes arranged along the distribution channel for receiving the blast air from the distribution channel and dispensing the blast air toward the upper side of a respective one of the printed sheets in the respective connected device to press the respective printed sheet toward a support in the connected device so that the respective printed sheets processed by each connected device can be admitted with blast air on the upper side to change or maintain a position of the respective printed sheet;
- and
- a control unit arranged to separately control the blast air generated by each blower.
An apparatus for producing printed products, such as books, magazines, brochures, catalogues or the like, comprising:
- a plurality of connected devices for processing printed sheets;
- an air supply including blowers that generate blast air, wherein at least two of the connected devices are each arranged to use blast air of respectively one blower so that the printed sheets processed by each connected device can be admitted with blast air either to change or maintain a position of the printed sheets;
- and
- a control unit arranged to control the blast air generated by the blowers;
- wherein the blast air generated by the blowers is adjustable in dependence on parameters including at least one of a production speed, a type and grammage of printed paper folded to form the printed sheets format of the printed sheets, number of pages or a type of fold for the printed sheets, a composition of the printed product, a use of guide elements, and an arrangement of the connected devices within the apparatus;
- and
- wherein the control unit determines operating data for the blowers in dependence on the parameters and the blowers are actuatable with aid of the operating data.
