Abstract
A delivery for a printing machine that processes sheets passing through the latter in a processing direction, includes sheet brakes adjustable transversely to the processing direction and a respective braking element having a vacuum passing therethrough, the braking element being cooperatable with the sheet and revolving during the operation thereof, and a supporting element through which vacuum does not pass, the respective braking element being replaceable by the supporting element for converting one of the sheet brakes to a respective sheet support adjustable transversely to the processing direction; and a printing machine having such a delivery.
Claims14
A delivery for a printing machine processing sheets passing therethrough in a processing direction, comprising:
- modular braking elements each:
- formed with at least one opening adapted to be connected to a vacuum source;
- and
- having a braking insert;
- modular supporting elements each having a supporting insert substantially identical to said braking insert;
- and
- sheet handling devices each having:
- one of a plurality of substantially identical basic driving modules adapted to be connected to the vacuum source and to be selectively displaced transverse to the sheet processing direction, each of said basic driving modules having a receptacle;
- and
- a sheet carrying device revolvably disposed on said one basic driving module, said sheet carrying device being one of said elements, a respective one of said braking insert and said supporting insert being removably connected to said receptacle, said braking element adapted to apply a vacuum of the vacuum source to the sheet through said at least one opening, said supporting element preventing application of the vacuum to the sheet.
In combination with a sheet-processing printing machine processing sheets passing therethrough in a processing direction and having a vacuum source providing a vacuum, a delivery comprising:
- modular braking elements each:
- formed with at least one opening adapted to be connected to the vacuum source;
- and
- having a braking insert;
- modular supporting elements each having a supporting insert substantially identical to said braking insert;
- and
- sheet handling devices each having;
- one of a plurality of substantially identical basic driving modules connected to the vacuum source and selectively displaced transverse to the sheet processing direction, each of said basic driving modules having a receptacle;
- and
- a sheet carrying device revolvably disposed on said one basic driving module, said sheet carrying device being one of said elements, a respective one of said braking insert and said supporting insert being removably connected to said receptacle, said braking element applying the vacuum of the vacuum source to the sheet through said at least one opening, said supporting element preventing application of the vacuum to the sheet.
