Shed feeder
The stream feeder is a term used in printing technology and describes a transport system for sheet feeding of sheet-fed presses .
The stream feeder transfers flaky sheets of paper to the first printing unit of the printing machine. Here, a vacuum suction head separates the sheets initially only at the bow end, after lifting sucker the sheet end lift and the sheet separation is supported by blowing air and wiper. Timed blown air is blown between the sheets on the feeder stack and causes the entire top sheet to float, which is now transported to the shingled stream on the belt table with suction cups. The next sheet is already lifted from the stack when the preceding sheet has only left it by a third. The speed of movement of the shingled stream is about a third of the printing speed. As a result, an increased printing speed of up to 23,000 sheets per hour, combined with the precision required for sheet alignment in the front and side marks , is possible.
The counterpart to the stream feeder is the single sheet feeder .
