Abstract

A sheet enters the reverser at input 1 and lifts kicker plate 2, which may be spring-loaded. Top roller 3 and pinch roller 4 drive the sheet between a plurality of top wires 5 and bottom wires 6. The bottom surfaces of top wires 5 interfere with the top surfaces of bottom wires 6, thus causing the sheet to be corrugated perpendicular to its direction of movement, and to acquire considerable beam strength. The strengthened sheet reaches spring-loaded kicker wires 7 and bends them back until the trailing edge of sheet clears rollers 3 and 4. Now, kicker plate 2 moves the trailing edge of the sheet down into the grooves of pinch roller 4 until it engages the nip between pinch roller 4 and turnaround roll 8, pushed by kicker wires 7. The sheet leaves the reverser at exit 10.

Sheet Reverser

A sheet enters the reverser at input 1 and lifts kicker plate 2, which may be spring-loaded. Top roller 3 and pinch roller 4 drive the sheet between a plurality of top wires 5 and bottom wires 6. The bottom surfaces of top wires 5 interfere with the top surfaces of bottom wires 6, thus causing the sheet to be corrugated perpendicular to its direction of movement, and to acquire considerable beam strength. The strengthened sheet reaches spring-loaded kicker wires 7 and bends them back until the trailing edge of sheet clears rollers 3 and 4. Now, kicker plate 2 moves the trailing edge of the sheet down into the grooves of pinch roller 4 until it engages the nip between pinch roller 4 and turnaround roll 8, pushed by kicker wires 7. The sheet leaves the reverser at exit 10.

Sheets that are not to be reversed enter at input 9 and leave via exit 10.
