Abstract

This paper bin includes a number of gravity-biased metal rings, which serve the dual purpose of retarding paper sheets as they are fed into the bin and holding down the edge of the sheets already deposited in the bin. The metal rings hang on a pivot axis which incline to the direction of sheet travel, and span a distance which insures edge cooperation with sheets of varying width.

Paper Bin

This paper bin includes a number of gravity-biased metal rings, which serve the dual purpose of retarding paper sheets as they are fed into the bin and holding down the edge of the sheets already deposited in the bin. The metal rings hang on a pivot axis which incline to the direction of sheet travel, and span a distance which insures edge cooperation with sheets of varying width.

Fig. 1 shows a side view of paper bin 10 wherein a stack of 8-inch wide paper 11 has been deposited. Three metal rings 12 are pivotally hung from bin top 13. As seen in Fig. 2, the rings are hung at an angle to the direction 14 of sheet travel.

As seen in Fig. 1, a sheet 15 which is about to enter the bin 10 has a typical edge curl, indicated at 16. This sheet, which moves at relatively high speed, hits rings 12 and has a portion of its kinetic energy absorbed by upward deflection of the rings. This deflection is generally clockwise, as viewed from the mouth 17 of the bin 10. The sheet 15 then moves at a lower speed to impact the end 18 of the bin.

As the bin 10 fills, rings 12 settle down onto the trailing curled edge 16 of the sheets, holding the edge down, to prevent interference with the subsequent sheet 15 to be placed in the bin 10.

The effective length 19 of each ring 12 is such as to span sheets having different widths, such as 10-inch widths as shown at 20, while being effective to hold down the trailing curled edge 16 thereof.
