Abstract

The tip of pressure shoe 10 is located on the vertical center line of pressure roller 15 and is spaced from belt 20 less than the thickness of card 25. Shoe 10 has a card lead-in surface 11 and is spring-loaded to yield as cards 25 come between it and belt 20. The card contacting surface of belt 20 has a relatively high coefficient of friction for driving cards 25. Shoe 10 has a low coefficient of friction to enable cards to slide over it.

Card Stacker

The tip of pressure shoe 10 is located on the vertical center line of pressure roller 15 and is spaced from belt 20 less than the thickness of card 25. Shoe 10 has a card lead-in surface 11 and is spring-loaded to yield as cards 25 come between it and belt 20. The card contacting surface of belt 20 has a relatively high coefficient of friction for driving cards 25. Shoe 10 has a low coefficient of friction to enable cards to slide over it.

Cards 25 are fed by the cooperative action of shoe 10 and belt 20 between fixed guide 30 and spring urged stacking platform 40. The leading edge of card 25 strikes stop 45 just after the trailing edge leaves the bite between 10 and 20. Guide 30 temporarily deforms cards 25 from their normally flat condition after they are diverted from the card path by electromagnetically operated selector 50.

After the trailing edge leaves the bite between 10 and 20, it quickly snaps into stacking position and card 25 resumes its normal flat condition. The trailing edge is free to quickly pivot out of the path of the oncoming card because shoe surface 12 and guide surfaces 55 flanking shoe 10 slope away from stop 45.
