Abstract
A delivery device in a folding apparatus of a printing press includes a fan wheel or several fan wheels disposed next to one another. The fan wheels are formed of individual fan blades, between which fan wheel pockets are formed. Leading edges of the fan blades have a first profile and trailing edges of the fan blades have a second profile.
Claims12
A delivery device in a folding apparatus of a printing press, comprising:
- at least one fan wheel, said fan wheel, said fan wheel being formed of individual fan blades having respective edges defining fan wheel pockets between respective leading and trailing fan blades for receiving incoming folded products, the respective edge of each of said trailing fan blades partly defining each of said pockets being a leading edge relative to the incoming folded product and being formed with a first profile having at least one folded-product slow-down path, and the respective edge of each of said leading fan blades partly defining each of said pockets being a trailing edge relative to the incoming folded product and being formed with a second profile having a plurality of slow-down paths different from said one slow-down path of said first profile.
A delivery device in a folding apparatus of a printing press, comprising:
- at least one fan wheel, said fan wheel being formed of individual fan blades having respective edges defining fan wheel pockets between respective leading and trailing said fan blades for receiving incoming folded products,
- the respective edge of each of said training fan blades partly defining each of said pockets being a leading edge relative to the incoming folded product and being formed with a first profile, and the respective edge of each of said a leading fan blades partly defining each of said pockets being a trailing edge relative to the incoming folded product, and being formed with a second profile, each of said second profiles of said fan blades at said trailing edges having a delay path, a first concave recess and a second concave recess.
A delivery device in a folding apparatus of a printing press, comprising:
- at least one fan wheel, said fan wheel being formed of individual fan blades having respective edges defining fan wheel pockets between respective leading and trailing said fan blades for receiving incoming folded products,
- the respective edge of each of said trailing fan blades partly defining each of said pockets being a leading edge relative to the incoming folded product and being formed with a first profile, and the respective edge of each of said a leading fan blades partly defining each of said pockets being a trailing edge relative to the incoming folded product, and being formed with a second profile, each of said second profiles of said fan blades at said trailing edges having a delay path, a first concave recess and a second concave recess, each of said first profiles of said fan blades at said leading edges having an impact path, and said leading edge in the vicinity of said impact path and said trailing edge in the vicinity of said delay path of said first concave recess and said second concave recess being formed of ink-repellent material.
