Separating Cut Sheets

There is disclosed an improved technique for separating cut sheets by the principle of roll wave generation as first disclosed in U.S. Patent 3,008,709. A stack is caused to shingle in a fan-like manner about a predetermined point.

In Figs. 1 and 2, a stack 1 of cut sheets is desired to be shingled. The shingler device includes a free-rolling roller 3 attached to rotatable disk 7. Disk 7 rotates in direction 9 about shaft 5. The entire device is force loaded into stack 1 (by means not shown) such that post 5 and free-rolling roller 3 each depress stack 1, as shown in Fig. 2. The rotation of disk 7 in the direction of arrow 9 causes the roll wave created by free-rolling roller 3 to travel through stack 1, thereby separating it.

The following advantages result from a shingler as above described. Only one free-rolling member 3, which may be a ball, is required as opposed to previous devices having a plurality of such free-rolling members positioned about the periphery of a wheel or disk. Unlike the device shown in the above referenced patent, a stack of sheets to be separated is pivoted about a known point, that is, one created by the depression of pivot post 5.
