Abstract
A method and an apparatus for driving a fan wheel of a web-fed printing press is disclosed. The fan wheel is driven, at least in a predetermined time period (tv-tD) in the production cycle, at a fan wheel speed, which in addition to a rotary drive speed component is comprised of an oscillating speed component.
Claims18
A method for driving a fan wheel of a web-fed printing press, comprising the step of driving the fan wheel, at least in a predetermined time period (tv-tD) in a production cycle, at a fan wheel speed, which in addition to a rotary drive speed component is comprised of an oscillating speed component such that the oscillating speed component vibrates the fan wheel.
A printing press delivery module, comprising:
- a drive device coupled to a fan wheel wherein the drive device is controlled by a controller such that the fan wheel is driveable, at least in a predetermined fan wheel rotational speed range (0-nD), at a fan wheel speed, which in addition to a rotary drive speed component has an oscillating speed component such that the oscillating speed component vibrates the fan wheel.
