Abstract
A sheet conveying system comprising a first conveyor and a second conveyor arranged downstream of the first conveyor in a transport direction for taking-over a sheet from the first conveyor, the first conveyor having a belt that is driven to move over a stationary attraction mechanism, the attraction mechanism being arranged to exert, onto a sheet conveyed on the first conveyor, an attraction force that is proportional to an area of coverage of the sheet on the attraction mechanism, characterized in that the attraction mechanism is arranged to attract the sheet with a larger force per area in a downstream zone of the first conveyor than in an upstream zone thereof.

A sheet conveying system comprising a first conveyor and a second conveyor arranged downstream of the first conveyor in a transport direction for taking-over a sheet from the first conveyor, the first conveyor having a belt that is driven to move over a stationary attraction mechanism, the attraction mechanism being arranged to exert, onto a sheet conveyed on the first conveyor, an attraction force that is proportional to an area of coverage of the sheet on the attraction mechanism, characterized in that the attraction mechanism is arranged to attract the sheet with a larger force per area in a downstream zone of the first conveyor when the sheet is in the downstream zone than in an upstream zone of the first conveyor when the sheet is in the upstream zone.
A sheet conveying system comprising a first conveyor and a second conveyor arranged downstream of the first conveyor in a transport direction for taking-over a sheet from the first conveyor, the first conveyor having a belt that is driven to move over a stationary attraction mechanism, the attraction mechanism being arranged to exert, onto a sheet conveyed on the first conveyor, an attraction force that is proportional to an area of coverage of the sheet on the attraction mechanism, characterized in that the attraction mechanism is arranged to attract the sheet with a larger force per area in a downstream zone of the first conveyor than in an upstream zone thereof,
- wherein the second conveyor has a belt that is driven to move over a second attraction mechanism, the second attraction mechanism being arranged to exert, onto a sheet conveyed on the second conveyor, an attraction force that is proportional to an area of coverage of the sheet on the second attraction mechanism, and
- wherein the attraction mechanism of the first conveyor is arranged to attract a sheet with a larger force per area in a downstream zone of the first conveyor than that the second attraction mechanism is arranged to attract a sheet with.
