Abstract
In a sheet transport system for a reproduction machine, the transport system defining a transport channel through which the sheet travels in a transport direction, an improvement comprises one or more plenums associated with the transport channel, each plenum connectable to an air flow supply, and one or more openings between each plenum and the transport channel. At least one of the one or more openings is arranged to direct air flowing through the plenum into the transport channel in the transport direction.
Claims17
A sheet transport system for a reproduction machine, comprising:
- a transport chute having an inlet through with a sheet enters the transport chute and an outlet from which the sheet exits the transport chute after traveling though the transport chute in a transport direction, the transport chute being substantially enclosed about the sheet traveling therethrough between the inlet and the outlet;
- a plenum associated with the transport chute, the plenum connectable to an air flow supply;
- and
- an opening between the plenum and the substantially enclosed transport chute to direct air flowing through said plenum into the transport chute in the transport direction, said opening being a slot extending across the transport chute transverse to the transport direction and being disposed between the inlet and the outlet of the transport chute,
- wherein said transport chute and said opening are sized to achieve air flow into the transport chute sufficient to produce a net air drag force in the transport direction from the inlet to the outlet to transport the sheet through said transport chute by said air flow.

A sheet transport system for a reproduction machine comprising:
- a transport chute having an inlet through which a sheet enters the transport chute and an outlet from which the sheet exits the transport chute after traveling through the transport chute in a transport direction, the transport chute being substantially enclosed about the sheet traveling therethrough between the inlet and the outlet;
- a first plenum associated with the transport chute, the first plenum connectable to an air flow supply;
- a second plenum associated with the transport chute, the second plenum connectable to an air flow supply;
- an opening between the first plenum and the substantially enclosed transport chute to direct air flow through said first plenum into the transport chute in the transport direction, said opening disposed between the inlet and the outlet of the transport chute, said transport chute and said opening are sized to achieve air flow into the transport chute sufficient to produce a net air drag force in the transport direction from the inlet to the outlet to transport the sheet through said transport chute by said air flow;
- and
- a discharge outlet defined in the transport chute, the discharge outlet being positioned downstream of the first plenum and upstream of the second plenum, downstream and upstream being identified with reference to the transport direction, the discharge outlet being closer to the second plenum than to the first plenum.

- a first plenum associated with the transport chute, the first plenum connectable to an air flow supply;
- a second plenum associated with the transport chute, the second plenum connectable to an air flow supply, each plenum being disposed on the same side of the transport chute;
- an opening between the first plenum and the substantially enclosed transport chute to direct air flow through said first plenum into the transport chute in the transport direction, said opening disposed between the inlet and the outlet of the transport chute, said transport chute and said opening are sized to achieve air flow into the transport chute sufficient to produce a net air drag force in the transport direction from the inlet to the outlet to transport the sheet through said transport chute by said air flow;
- and
- a discharge outlet defined in the transport chute, the discharge outlet being positioned between the plenums.
