Aperture Card Stacking

Stacking interference between the edges of an incoming card and the aperture in a stacked card is eliminated. This is by providing a thin, flexible flap over the aperture of the stacked card during entry of the incoming card.

A cyclically operating stacking segment 1 secured to rotating shaft 2 has spring clip 3 mounted on it with a pair of hinge tabs 4 in which leg 5 of U shaped bracket 6 is rotatably supported. Bracket leg 7 has strip 8 fixed to it on which is secured thin flexible flap 9 of material such as MYLAR*. Spring 10 mounted on bracket 6 urges the flap outwardly from the shaft and roll. Flap 9 is of sufficient width to extend beyond edge 11 of aperture 12 in stacked card 13.

As shaft 2 rotates, flap 9 engages card 13 and is pulled across aperture 12. Segment 1 then engages leading edge 14 of the incoming card pushing it downwardly onto flap 9. Thus, the incoming card and flap move across aperture edge 11 without interference. Stacker side plate 15 is formed with cutout 16 to provide clearance for the flap. * MYLAR is a trademark of E.I. DuPont de Nemours & Co.
