Abstract

A card approaches the stacking device under control of a pair of cooperating drive rolls 11 and is received between eject roll 13 and pressure shoe 14. Extending transversely of the path of card 15 as it emerges from between roll 13 and shoe 14 is cupping guide 16 on which is mounted a pair of transversely spaced kickdown springs 18. The leading edge of card 15 engages stacking guide 20. This has terminal end portion 21 with a lower sweep radius that contacts the top of card deck 23 accumulated on upwardly biased platform 25. A card 15, delivered by rolls 11, is controlled and driven by roll 13 into the stacker. Card 15 is engaged by guide 16 and springs 18 to effect a transverse bow and provide longitudinal card stability.

A card approaches the stacking device under control of a pair of cooperating drive rolls 11 and is received between eject roll 13 and pressure shoe 14. Extending transversely of the path of card 15 as it emerges from between roll 13 and shoe 14 is cupping guide 16 on which is mounted a pair of transversely spaced kickdown springs 18. The leading edge of card 15 engages stacking guide 20. This has terminal end portion 21 with a lower sweep radius that contacts the top of card deck 23 accumulated on upwardly biased platform 25. A card 15, delivered by rolls 11, is controlled and driven by roll 13 into the stacker. Card 15 is engaged by guide 16 and springs 18 to effect a transverse bow and provide longitudinal card stability. Card 15 moves into the stacker with the leading edge, following the lower surface of guide 20, being released from control and driving engagement by roll 13 as terminal end 21 of guide 20 is approached to permit capture on the top of deck 23 beneath stacking guide distal end 21. The free flight of card 15 is limited to a few thousandths of an inch between the termination of contact with roll 13 and arrest beneath guide 20 with the simultaneous downward thrust of the card trailing end by springs 18.
