| A carton blank prefeeding apparatus generally comprising a carton blank stack magazine situated above a conveyor. The conveyor is preferably tri-sectional, having a blank withdrawal section, an intermediate section and a delivery section. Typically, the blank withdrawal section and the delivery section are pivotally attached to the supporting subframe, thus allowing adjustment of the relative angles of inclination between successive conveyor sections. An upper conveyor may be situated above the delivery section to cooperate therewith in the delivery of the blanks. A center driven pulley may be utilized to drive the tri-sectional conveyor directly, as well as the upper conveyor via an interconnecting drive belt. A pair of opposing blank flexing members situated laterally of the conveyor facilitate the removal of debris on the blanks. The process of the invention contemplates first providing a stack of carton blanks. Second, individual blanks are removed from the bottom of the stack in shingled arrangement. Next, the blanks are flexed while in the shingled arrangement such that they are convex. Then the blanks are restacked. | ||||||

| 157 | Ticket counter and endorser | US465700 | 1974-04-30 | US3944210A | 1976-03-16 | George P. McInerny |
| Apparatus for counting and endorsing documents and more particularly tickets dimensionally within the preferred range from 1 inch by 2 inches to 2 inches by 5.5 inches and in the thickness range from two mils to 14 mils. The stack of tickets is placed in an in-feed hopper and is engaged by an eccentric bottom feed picker to drive preferably the bottom-most document toward a drive wheel and stripper wheel assembly to permit documents to pass only in single file beyond the stripper device. The documents are fed in single file between cooperating belts until they are picked up by acceleration means which abruptly accelerates the documents to provide a gap therebetween suitable for counting purposes.The documents are driven into a stacker wherein they are stacked in the same order in which they were loaded into the in-feed hopper. A stacker arm provides pressure on the building stack which pressure is continually reduced as the stack increases in height to assure a smooth stacking operation. The stacker back plate is adjustable to accommodate the documents of different lengths. A single drive belt is utilized to feed, drive and convey documents to the acceleration means.The documents may be endorsed by selectively moveable endorsing means arranged to prevent "back printing." A novel split retainer mechanism is utilized to facilitate fast removal and replacement of the endorser, ink roller and the endorser drum, while at the same time providing the capability of retaining and locking these elements in place during use. | ||||||
| 158 | Bottom sheet feeder using separation belt and retard pad | US34265373 | 1973-03-19 | US3895791A | 1975-07-22 | KRAMELL HANS P; HANSEN RICHARD C |
| A sheet separation belt is positioned at the bottom of a stack in a cut-away in the tray carrying the stack. The belt is carried by three rollers. One is located a distance from the edge of the stack. Another is located near the stack edge. A retard pad is biased against the belt between the second and third rollers. An infeed chute abutts or restrains the lead edge of the stack and is sloped to slope the stack. The slope generates a normal component between the stack and belt that enhances the feeding engagement. A blade is employed to clean contaminants from the belt.
