Title:
UNIVERSAL METERING HOPPER AND METHOD FOR HANDLING THICK OR THIN NEWSPAPER PRODUCTS
Document Type and Number:
WIPO Patent Application WO2000046108
Kind Code:
A3
Abstract:
The stack of newspapers rests upon a fore- and aft- narrow rail (34) on the shuttle plate so that a stiffening ridge is created in the body of the lowermost paper and at least several papers thereabove. During each feed stroke, a stop (160) at the front of the hopper permits the lowermost paper to exit from the hopper but blocks similar movement of the second paper and all those above it. The stop is offset laterally from the path of travel of the rail so that the area immediately above the rail is open and unrestricted, allowing the peak of the ridge to pass out of the hopper even if the paper has an accidentally rolled up, fat leading edge. A downwardly and outwardly flaring deflecting leg (162) at the lower end of the stop pushes down on the side slope of the ridge as the paper moves forwardly toward the nip rollers so as to bend the side slope downwardly away from the surface of the next paper, thus encouraging separation of the lower paper from those above it in the stack.
